It’s because the last thing any of us needs during the busy season is a phone call complaining about murky pond water!&amp;nbsp;&lt;br /&gt;&lt;br /&gt;To be healthy, a living ecosystem needs plants, fish, aeration, rocks and gravel, but to help keep the water clear in the vast majority of ponds, there must also be an adequate filtration system.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Three types of pond filters are available on the market: biological filters, mechanical filters and sterilizing units.&lt;i&gt;&amp;nbsp;Biological filters&amp;nbsp;&lt;/i&gt;use bacteria to break down pond wastes, converting them into less harmful compounds that can be taken up by aquatic plants as fertilizer.&lt;i&gt;Mechanical filters&amp;nbsp;&lt;/i&gt;physically trap and remove debris and sediment.&amp;nbsp;&lt;i&gt;Sterilizing units&amp;nbsp;&lt;/i&gt;pass water through a tube that houses an ultraviolet bulb: The UV light kills living microscopic particles in the water.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;In my experience, a combination of biological filtration with a proper mechanical filter (to remove solids before the water enters the biological filtration unit) is the most effective approach. I’ll discuss the reasons for this below.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;A Simple Process&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;The main function of a mechanical filter is to remove debris before it can sink to the bottom of the pond and decay. In many systems, a skimmer unit houses the filtration medium as well as the pump and its associated plumbing. Everything within the system is self-contained, meaning the skimmer won’t drain the pond if a leak develops in either the plumbing or the waterfalls.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;There are two main types of skimmers: box and floating skimmers. Both types filter the water by removing floating debris and waste before it’s had a chance to fall to the bottom of the pond — but the box skimmer is generally easier to maintain.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Box-style skimmers come with either vertical or horizontal filter mats. Horizontal mats lie flat, so there’s no sagging that distorts their shape. Also, they can’t clog to the point of preventing water passage, so there’s no danger of the pump running dry. By comparison, vertical mats require more frequent cleaning and need to be monitored to make sure there’s enough water in the chamber for safe pump operation.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;With either orientation, as water enters the skimmer the large debris is removed and the water is then further filtered through the mats. The water then travels through its buried plumbing and moves to the biological filter, where it’s further treated before re-entering the pond.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Water enters the biological filter, which is typically placed on the opposite side of the pond from the skimmer via a pipe located near the base of the unit. The water then flows from the bottom to the top of the device, traveling through the filtration medium housed inside the unit. This medium helps by removing fine- to medium-sized particles; the larger debris was removed in the skimmer.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The biological filter fills and ultimately overflows to cascade down rocks arranged into a naturalistic waterfall configuration. There’s the added benefit here in that the waterfall aerates the pond, assisting in the circulation and in the overall health of the water. (If a slower, stream effect is preferred, the unit simply needs to be sunk lower into the ground.)&lt;br /&gt;&lt;br /&gt;Biological filters on the market today range in size and can filter ponds up to 10,000 gallons. For larger ponds, multiple biological filters can be incorporated into the design.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Background Science&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;Mechanical and biological filtration are critical to processing the many types of nutrients found in a watergarden system, including fish wastes, uneaten fish food, leaves and runoff from lawns (to name just a few). Left to their own devices, these materials generate high levels of ammonia, a form of nitrogen that is highly toxic to fish and is also a major contributor to prolific algae growth.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;A biological filter does its job by virtue of the fact its filtering medium is impregnated with nitrifying (or facultative) bacteria that absorb ammonia and turn its&amp;nbsp;&lt;i&gt;nitrites&lt;/i&gt;&amp;nbsp;into less-dangerous&amp;nbsp;&lt;i&gt;nitrates.&amp;nbsp;&lt;/i&gt;&lt;br /&gt;&lt;br /&gt;(These bacteria require oxygen to live, so it’s important for the pond’s pump to run 24 hours a day, seven days a week. If the pump stops running, the waterfall also ceases to flow and aeration is eliminated, and the equations required to maintain the ecosystem are thrown out of whack. In particular, once the pump shuts down, the bacteria in the biological filter will quickly use up all of the available oxygen and die —&amp;nbsp;&lt;i&gt;not&lt;/i&gt;&amp;nbsp;a good thing.)&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Once the bacteria have done their work, the resulting nitrates are removed from the pond by another biological filtration method known as de-nitrification. This process occurs only in anaerobic (oxygen-free) areas of the pond, which is why it’s not necessarily bad for some areas of a pond to experience minimal water flow (such as on the bottom of the pond under an inch or so of gravel). The bacteria living in this area of the pond turn nitrates into nitrogen gas that is released into the atmosphere or absorbed by aquatic plants — or by algae, which is another reason why a pond without aquatic plants will become a maintenance nightmare.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;For any biological filtration to work, you need to put&amp;nbsp;&lt;i&gt;billions&lt;/i&gt;&amp;nbsp;of bacteria to work in purifying the water. They prefer to anchor onto things, which is why surface area is so important, with more surface area meaning more bacteria, and more bacteria meaning better biological filtration. This surface area is provided by filter media, rocks and gravel. Thus, a pond with gravel on the bottom will contain more surface area for bacteria than will a pond with an exposed liner on the bottom.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The simple process of repeatedly turning the water over through the mechanical and biological filters helps maintain high-quality water and aids in creating a naturally balanced, low-maintenance ecosystem. Add the remaining components of fish, plants, aeration, rock and gravel, and you’ll find greater success in creating easy-to-maintain watergardens for your clients.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;When those clients spend less time fiddling in the backyard on pond chores, it means they will enjoy more leisure time relaxing by their backyard oasis with a cool beverage in hand. So instead of spending your days on follow-up maintenance and troubleshooting calls, you can instead focus on more important things — such as gathering new clients!&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;&lt;i&gt;Dave Kelly&amp;nbsp;&lt;/i&gt;&lt;/b&gt;&lt;i&gt;is Vice President of Product Development for Aquascape, a waterfeature design and installation company headquartered in St. Charles, Ill.

It’s because the last thing any of us needs during the busy season is a phone call complaining about murky pond water!&amp;nbsp;&lt;br /&gt;&lt;br /&gt;To be healthy, a living ecosystem needs plants, fish, aeration, rocks and gravel, but to help keep the water clear in the vast majority of ponds, there must also be an adequate filtration system.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Three types of pond filters are available on the market: biological filters, mechanical filters and sterilizing units.&lt;i&gt;&amp;nbsp;Biological filters&amp;nbsp;&lt;/i&gt;use bacteria to break down pond wastes, converting them into less harmful compounds that can be taken up by aquatic plants as fertilizer.&lt;i&gt;Mechanical filters&amp;nbsp;&lt;/i&gt;physically trap and remove debris and sediment.&amp;nbsp;&lt;i&gt;Sterilizing units&amp;nbsp;&lt;/i&gt;pass water through a tube that houses an ultraviolet bulb: The UV light kills living microscopic particles in the water.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;In my experience, a combination of biological filtration with a proper mechanical filter (to remove solids before the water enters the biological filtration unit) is the most effective approach. I’ll discuss the reasons for this below.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;A Simple Process&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;The main function of a mechanical filter is to remove debris before it can sink to the bottom of the pond and decay. In many systems, a skimmer unit houses the filtration medium as well as the pump and its associated plumbing. Everything within the system is self-contained, meaning the skimmer won’t drain the pond if a leak develops in either the plumbing or the waterfalls.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;There are two main types of skimmers: box and floating skimmers. Both types filter the water by removing floating debris and waste before it’s had a chance to fall to the bottom of the pond — but the box skimmer is generally easier to maintain.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Box-style skimmers come with either vertical or horizontal filter mats. Horizontal mats lie flat, so there’s no sagging that distorts their shape. Also, they can’t clog to the point of preventing water passage, so there’s no danger of the pump running dry. By comparison, vertical mats require more frequent cleaning and need to be monitored to make sure there’s enough water in the chamber for safe pump operation.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;With either orientation, as water enters the skimmer the large debris is removed and the water is then further filtered through the mats. The water then travels through its buried plumbing and moves to the biological filter, where it’s further treated before re-entering the pond.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Water enters the biological filter, which is typically placed on the opposite side of the pond from the skimmer via a pipe located near the base of the unit. The water then flows from the bottom to the top of the device, traveling through the filtration medium housed inside the unit. This medium helps by removing fine- to medium-sized particles; the larger debris was removed in the skimmer.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The biological filter fills and ultimately overflows to cascade down rocks arranged into a naturalistic waterfall configuration. There’s the added benefit here in that the waterfall aerates the pond, assisting in the circulation and in the overall health of the water. (If a slower, stream effect is preferred, the unit simply needs to be sunk lower into the ground.)&lt;br /&gt;&lt;br /&gt;Biological filters on the market today range in size and can filter ponds up to 10,000 gallons. For larger ponds, multiple biological filters can be incorporated into the design.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Background Science&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;Mechanical and biological filtration are critical to processing the many types of nutrients found in a watergarden system, including fish wastes, uneaten fish food, leaves and runoff from lawns (to name just a few). Left to their own devices, these materials generate high levels of ammonia, a form of nitrogen that is highly toxic to fish and is also a major contributor to prolific algae growth.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;A biological filter does its job by virtue of the fact its filtering medium is impregnated with nitrifying (or facultative) bacteria that absorb ammonia and turn its&amp;nbsp;&lt;i&gt;nitrites&lt;/i&gt;&amp;nbsp;into less-dangerous&amp;nbsp;&lt;i&gt;nitrates.&amp;nbsp;&lt;/i&gt;&lt;br /&gt;&lt;br /&gt;(These bacteria require oxygen to live, so it’s important for the pond’s pump to run 24 hours a day, seven days a week. If the pump stops running, the waterfall also ceases to flow and aeration is eliminated, and the equations required to maintain the ecosystem are thrown out of whack. In particular, once the pump shuts down, the bacteria in the biological filter will quickly use up all of the available oxygen and die —&amp;nbsp;&lt;i&gt;not&lt;/i&gt;&amp;nbsp;a good thing.)&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Once the bacteria have done their work, the resulting nitrates are removed from the pond by another biological filtration method known as de-nitrification. This process occurs only in anaerobic (oxygen-free) areas of the pond, which is why it’s not necessarily bad for some areas of a pond to experience minimal water flow (such as on the bottom of the pond under an inch or so of gravel). The bacteria living in this area of the pond turn nitrates into nitrogen gas that is released into the atmosphere or absorbed by aquatic plants — or by algae, which is another reason why a pond without aquatic plants will become a maintenance nightmare.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;For any biological filtration to work, you need to put&amp;nbsp;&lt;i&gt;billions&lt;/i&gt;&amp;nbsp;of bacteria to work in purifying the water. They prefer to anchor onto things, which is why surface area is so important, with more surface area meaning more bacteria, and more bacteria meaning better biological filtration. This surface area is provided by filter media, rocks and gravel. Thus, a pond with gravel on the bottom will contain more surface area for bacteria than will a pond with an exposed liner on the bottom.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The simple process of repeatedly turning the water over through the mechanical and biological filters helps maintain high-quality water and aids in creating a naturally balanced, low-maintenance ecosystem. Add the remaining components of fish, plants, aeration, rock and gravel, and you’ll find greater success in creating easy-to-maintain watergardens for your clients.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;When those clients spend less time fiddling in the backyard on pond chores, it means they will enjoy more leisure time relaxing by their backyard oasis with a cool beverage in hand.

It’s because the last thing any of us needs during the busy season is a phone call complaining about murky pond water!&amp;nbsp;&lt;br /&gt;&lt;br /&gt;To be healthy, a living ecosystem needs plants, fish, aeration, rocks and gravel, but to help keep the water clear in the vast majority of ponds, there must also be an adequate filtration system.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Three types of pond filters are available on the market: biological filters, mechanical filters and sterilizing units.&lt;i&gt;&amp;nbsp;Biological filters&amp;nbsp;&lt;/i&gt;use bacteria to break down pond wastes, converting them into less harmful compounds that can be taken up by aquatic plants as fertilizer.&lt;i&gt;Mechanical filters&amp;nbsp;&lt;/i&gt;physically trap and remove debris and sediment.&amp;nbsp;&lt;i&gt;Sterilizing units&amp;nbsp;&lt;/i&gt;pass water through a tube that houses an ultraviolet bulb: The UV light kills living microscopic particles in the water.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;In my experience, a combination of biological filtration with a proper mechanical filter (to remove solids before the water enters the biological filtration unit) is the most effective approach. I’ll discuss the reasons for this below.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;A Simple Process&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;The main function of a mechanical filter is to remove debris before it can sink to the bottom of the pond and decay. In many systems, a skimmer unit houses the filtration medium as well as the pump and its associated plumbing. Everything within the system is self-contained, meaning the skimmer won’t drain the pond if a leak develops in either the plumbing or the waterfalls.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;There are two main types of skimmers: box and floating skimmers. Both types filter the water by removing floating debris and waste before it’s had a chance to fall to the bottom of the pond — but the box skimmer is generally easier to maintain.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Box-style skimmers come with either vertical or horizontal filter mats. Horizontal mats lie flat, so there’s no sagging that distorts their shape. Also, they can’t clog to the point of preventing water passage, so there’s no danger of the pump running dry. By comparison, vertical mats require more frequent cleaning and need to be monitored to make sure there’s enough water in the chamber for safe pump operation.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;With either orientation, as water enters the skimmer the large debris is removed and the water is then further filtered through the mats. The water then travels through its buried plumbing and moves to the biological filter, where it’s further treated before re-entering the pond.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Water enters the biological filter, which is typically placed on the opposite side of the pond from the skimmer via a pipe located near the base of the unit. The water then flows from the bottom to the top of the device, traveling through the filtration medium housed inside the unit. This medium helps by removing fine- to medium-sized particles; the larger debris was removed in the skimmer.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The biological filter fills and ultimately overflows to cascade down rocks arranged into a naturalistic waterfall configuration. There’s the added benefit here in that the waterfall aerates the pond, assisting in the circulation and in the overall health of the water. (If a slower, stream effect is preferred, the unit simply needs to be sunk lower into the ground.)&lt;br /&gt;&lt;br /&gt;Biological filters on the market today range in size and can filter ponds up to 10,000 gallons. For larger ponds, multiple biological filters can be incorporated into the design.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Background Science&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;Mechanical and biological filtration are critical to processing the many types of nutrients found in a watergarden system, including fish wastes, uneaten fish food, leaves and runoff from lawns (to name just a few). Left to their own devices, these materials generate high levels of ammonia, a form of nitrogen that is highly toxic to fish and is also a major contributor to prolific algae growth.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;A biological filter does its job by virtue of the fact its filtering medium is impregnated with nitrifying (or facultative) bacteria that absorb ammonia and turn its&amp;nbsp;&lt;i&gt;nitrites&lt;/i&gt;&amp;nbsp;into less-dangerous&amp;nbsp;&lt;i&gt;nitrates.&amp;nbsp;&lt;/i&gt;&lt;br /&gt;&lt;br /&gt;(These bacteria require oxygen to live, so it’s important for the pond’s pump to run 24 hours a day, seven days a week. If the pump stops running, the waterfall also ceases to flow and aeration is eliminated, and the equations required to maintain the ecosystem are thrown out of whack. In particular, once the pump shuts down, the bacteria in the biological filter will quickly use up all of the available oxygen and die —&amp;nbsp;&lt;i&gt;not&lt;/i&gt;&amp;nbsp;a good thing.)&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Once the bacteria have done their work, the resulting nitrates are removed from the pond by another biological filtration method known as de-nitrification. This process occurs only in anaerobic (oxygen-free) areas of the pond, which is why it’s not necessarily bad for some areas of a pond to experience minimal water flow (such as on the bottom of the pond under an inch or so of gravel). The bacteria living in this area of the pond turn nitrates into nitrogen gas that is released into the atmosphere or absorbed by aquatic plants — or by algae, which is another reason why a pond without aquatic plants will become a maintenance nightmare.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;For any biological filtration to work, you need to put&amp;nbsp;&lt;i&gt;billions&lt;/i&gt;&amp;nbsp;of bacteria to work in purifying the water. They prefer to anchor onto things, which is why surface area is so important, with more surface area meaning more bacteria, and more bacteria meaning better biological filtration. This surface area is provided by filter media, rocks and gravel. Thus, a pond with gravel on the bottom will contain more surface area for bacteria than will a pond with an exposed liner on the bottom.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The simple process of repeatedly turning the water over through the mechanical and biological filters helps maintain high-quality water and aids in creating a naturally balanced, low-maintenance ecosystem. Add the remaining components of fish, plants, aeration, rock and gravel, and you’ll find greater success in creating easy-to-maintain watergardens for your clients.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;When those clients spend less time fiddling in the backyard on pond chores, it means they will enjoy more leisure time relaxing by their backyard oasis with a cool beverage in hand. So instead of spending your days on follow-up maintenance and troubleshooting calls, you can instead focus on more important things — such as gathering new clients!&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;&lt;i&gt;Dave Kelly&amp;nbsp;&lt;/i&gt;&lt;/b&gt;&lt;i&gt;is Vice President of Product Development for Aquascape, a waterfeature design and installation company headquartered in St. Charles, Ill.

It’s because the last thing any of us needs during the busy season is a phone call complaining about murky pond water!&amp;nbsp;&lt;br /&gt;&lt;br /&gt;To be healthy, a living ecosystem needs plants, fish, aeration, rocks and gravel, but to help keep the water clear in the vast majority of ponds, there must also be an adequate filtration system.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Three types of pond filters are available on the market: biological filters, mechanical filters and sterilizing units.&lt;i&gt;&amp;nbsp;Biological filters&amp;nbsp;&lt;/i&gt;use bacteria to break down pond wastes, converting them into less harmful compounds that can be taken up by aquatic plants as fertilizer.&lt;i&gt;Mechanical filters&amp;nbsp;&lt;/i&gt;physically trap and remove debris and sediment.&amp;nbsp;&lt;i&gt;Sterilizing units&amp;nbsp;&lt;/i&gt;pass water through a tube that houses an ultraviolet bulb: The UV light kills living microscopic particles in the water.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;In my experience, a combination of biological filtration with a proper mechanical filter (to remove solids before the water enters the biological filtration unit) is the most effective approach. I’ll discuss the reasons for this below.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;A Simple Process&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;The main function of a mechanical filter is to remove debris before it can sink to the bottom of the pond and decay. In many systems, a skimmer unit houses the filtration medium as well as the pump and its associated plumbing. Everything within the system is self-contained, meaning the skimmer won’t drain the pond if a leak develops in either the plumbing or the waterfalls.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;There are two main types of skimmers: box and floating skimmers. Both types filter the water by removing floating debris and waste before it’s had a chance to fall to the bottom of the pond — but the box skimmer is generally easier to maintain.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Box-style skimmers come with either vertical or horizontal filter mats. Horizontal mats lie flat, so there’s no sagging that distorts their shape. Also, they can’t clog to the point of preventing water passage, so there’s no danger of the pump running dry. By comparison, vertical mats require more frequent cleaning and need to be monitored to make sure there’s enough water in the chamber for safe pump operation.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;With either orientation, as water enters the skimmer the large debris is removed and the water is then further filtered through the mats. The water then travels through its buried plumbing and moves to the biological filter, where it’s further treated before re-entering the pond.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Water enters the biological filter, which is typically placed on the opposite side of the pond from the skimmer via a pipe located near the base of the unit. The water then flows from the bottom to the top of the device, traveling through the filtration medium housed inside the unit. This medium helps by removing fine- to medium-sized particles; the larger debris was removed in the skimmer.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The biological filter fills and ultimately overflows to cascade down rocks arranged into a naturalistic waterfall configuration. There’s the added benefit here in that the waterfall aerates the pond, assisting in the circulation and in the overall health of the water. (If a slower, stream effect is preferred, the unit simply needs to be sunk lower into the ground.)&lt;br /&gt;&lt;br /&gt;Biological filters on the market today range in size and can filter ponds up to 10,000 gallons. For larger ponds, multiple biological filters can be incorporated into the design.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Background Science&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;Mechanical and biological filtration are critical to processing the many types of nutrients found in a watergarden system, including fish wastes, uneaten fish food, leaves and runoff from lawns (to name just a few). Left to their own devices, these materials generate high levels of ammonia, a form of nitrogen that is highly toxic to fish and is also a major contributor to prolific algae growth.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;A biological filter does its job by virtue of the fact its filtering medium is impregnated with nitrifying (or facultative) bacteria that absorb ammonia and turn its&amp;nbsp;&lt;i&gt;nitrites&lt;/i&gt;&amp;nbsp;into less-dangerous&amp;nbsp;&lt;i&gt;nitrates.&amp;nbsp;&lt;/i&gt;&lt;br /&gt;&lt;br /&gt;(These bacteria require oxygen to live, so it’s important for the pond’s pump to run 24 hours a day, seven days a week. If the pump stops running, the waterfall also ceases to flow and aeration is eliminated, and the equations required to maintain the ecosystem are thrown out of whack. In particular, once the pump shuts down, the bacteria in the biological filter will quickly use up all of the available oxygen and die —&amp;nbsp;&lt;i&gt;not&lt;/i&gt;&amp;nbsp;a good thing.)&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Once the bacteria have done their work, the resulting nitrates are removed from the pond by another biological filtration method known as de-nitrification. This process occurs only in anaerobic (oxygen-free) areas of the pond, which is why it’s not necessarily bad for some areas of a pond to experience minimal water flow (such as on the bottom of the pond under an inch or so of gravel). The bacteria living in this area of the pond turn nitrates into nitrogen gas that is released into the atmosphere or absorbed by aquatic plants — or by algae, which is another reason why a pond without aquatic plants will become a maintenance nightmare.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;For any biological filtration to work, you need to put&amp;nbsp;&lt;i&gt;billions&lt;/i&gt;&amp;nbsp;of bacteria to work in purifying the water. They prefer to anchor onto things, which is why surface area is so important, with more surface area meaning more bacteria, and more bacteria meaning better biological filtration. This surface area is provided by filter media, rocks and gravel. Thus, a pond with gravel on the bottom will contain more surface area for bacteria than will a pond with an exposed liner on the bottom.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The simple process of repeatedly turning the water over through the mechanical and biological filters helps maintain high-quality water and aids in creating a naturally balanced, low-maintenance ecosystem. Add the remaining components of fish, plants, aeration, rock and gravel, and you’ll find greater success in creating easy-to-maintain watergardens for your clients.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;When those clients spend less time fiddling in the backyard on pond chores, it means they will enjoy more leisure time relaxing by their backyard oasis with a cool beverage in hand. So instead of spending your days on follow-up maintenance and troubleshooting calls, you can instead focus on more important things — such as gathering new clients!&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;&lt;i&gt;Dave Kelly&amp;nbsp;&lt;/i&gt;&lt;/b&gt;&lt;i&gt;is Vice President of Product Development for Aquascape, a waterfeature design and installation company headquartered in St. Charles, Ill.

It’s because the last thing any of us needs during the busy season is a phone call complaining about murky pond water!&amp;nbsp;&lt;br /&gt;&lt;br /&gt;To be healthy, a living ecosystem needs plants, fish, aeration, rocks and gravel, but to help keep the water clear in the vast majority of ponds, there must also be an adequate filtration system.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Three types of pond filters are available on the market: biological filters, mechanical filters and sterilizing units.&lt;i&gt;&amp;nbsp;Biological filters&amp;nbsp;&lt;/i&gt;use bacteria to break down pond wastes, converting them into less harmful compounds that can be taken up by aquatic plants as fertilizer.&lt;i&gt;Mechanical filters&amp;nbsp;&lt;/i&gt;physically trap and remove debris and sediment.&amp;nbsp;&lt;i&gt;Sterilizing units&amp;nbsp;&lt;/i&gt;pass water through a tube that houses an ultraviolet bulb: The UV light kills living microscopic particles in the water.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;In my experience, a combination of biological filtration with a proper mechanical filter (to remove solids before the water enters the biological filtration unit) is the most effective approach. I’ll discuss the reasons for this below.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;A Simple Process&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;The main function of a mechanical filter is to remove debris before it can sink to the bottom of the pond and decay. In many systems, a skimmer unit houses the filtration medium as well as the pump and its associated plumbing. Everything within the system is self-contained, meaning the skimmer won’t drain the pond if a leak develops in either the plumbing or the waterfalls.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;There are two main types of skimmers: box and floating skimmers. Both types filter the water by removing floating debris and waste before it’s had a chance to fall to the bottom of the pond — but the box skimmer is generally easier to maintain.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Box-style skimmers come with either vertical or horizontal filter mats. Horizontal mats lie flat, so there’s no sagging that distorts their shape. Also, they can’t clog to the point of preventing water passage, so there’s no danger of the pump running dry. By comparison, vertical mats require more frequent cleaning and need to be monitored to make sure there’s enough water in the chamber for safe pump operation.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;With either orientation, as water enters the skimmer the large debris is removed and the water is then further filtered through the mats. The water then travels through its buried plumbing and moves to the biological filter, where it’s further treated before re-entering the pond.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Water enters the biological filter, which is typically placed on the opposite side of the pond from the skimmer via a pipe located near the base of the unit. The water then flows from the bottom to the top of the device, traveling through the filtration medium housed inside the unit. This medium helps by removing fine- to medium-sized particles; the larger debris was removed in the skimmer.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The biological filter fills and ultimately overflows to cascade down rocks arranged into a naturalistic waterfall configuration. There’s the added benefit here in that the waterfall aerates the pond, assisting in the circulation and in the overall health of the water. (If a slower, stream effect is preferred, the unit simply needs to be sunk lower into the ground.)&lt;br /&gt;&lt;br /&gt;Biological filters on the market today range in size and can filter ponds up to 10,000 gallons. For larger ponds, multiple biological filters can be incorporated into the design.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;Background Science&amp;nbsp;&lt;/b&gt;&lt;br /&gt;&lt;br /&gt;Mechanical and biological filtration are critical to processing the many types of nutrients found in a watergarden system, including fish wastes, uneaten fish food, leaves and runoff from lawns (to name just a few). Left to their own devices, these materials generate high levels of ammonia, a form of nitrogen that is highly toxic to fish and is also a major contributor to prolific algae growth.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;A biological filter does its job by virtue of the fact its filtering medium is impregnated with nitrifying (or facultative) bacteria that absorb ammonia and turn its&amp;nbsp;&lt;i&gt;nitrites&lt;/i&gt;&amp;nbsp;into less-dangerous&amp;nbsp;&lt;i&gt;nitrates.&amp;nbsp;&lt;/i&gt;&lt;br /&gt;&lt;br /&gt;(These bacteria require oxygen to live, so it’s important for the pond’s pump to run 24 hours a day, seven days a week. If the pump stops running, the waterfall also ceases to flow and aeration is eliminated, and the equations required to maintain the ecosystem are thrown out of whack. In particular, once the pump shuts down, the bacteria in the biological filter will quickly use up all of the available oxygen and die —&amp;nbsp;&lt;i&gt;not&lt;/i&gt;&amp;nbsp;a good thing.)&amp;nbsp;&lt;br /&gt;&lt;br /&gt;Once the bacteria have done their work, the resulting nitrates are removed from the pond by another biological filtration method known as de-nitrification. This process occurs only in anaerobic (oxygen-free) areas of the pond, which is why it’s not necessarily bad for some areas of a pond to experience minimal water flow (such as on the bottom of the pond under an inch or so of gravel). The bacteria living in this area of the pond turn nitrates into nitrogen gas that is released into the atmosphere or absorbed by aquatic plants — or by algae, which is another reason why a pond without aquatic plants will become a maintenance nightmare.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;For any biological filtration to work, you need to put&amp;nbsp;&lt;i&gt;billions&lt;/i&gt;&amp;nbsp;of bacteria to work in purifying the water. They prefer to anchor onto things, which is why surface area is so important, with more surface area meaning more bacteria, and more bacteria meaning better biological filtration. This surface area is provided by filter media, rocks and gravel. Thus, a pond with gravel on the bottom will contain more surface area for bacteria than will a pond with an exposed liner on the bottom.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;The simple process of repeatedly turning the water over through the mechanical and biological filters helps maintain high-quality water and aids in creating a naturally balanced, low-maintenance ecosystem. Add the remaining components of fish, plants, aeration, rock and gravel, and you’ll find greater success in creating easy-to-maintain watergardens for your clients.&amp;nbsp;&lt;br /&gt;&lt;br /&gt;When those clients spend less time fiddling in the backyard on pond chores, it means they will enjoy more leisure time relaxing by their backyard oasis with a cool beverage in hand. So instead of spending your days on follow-up maintenance and troubleshooting calls, you can instead focus on more important things — such as gathering new clients!&amp;nbsp;&lt;br /&gt;&lt;br /&gt;&lt;b&gt;&lt;i&gt;Dave Kelly&amp;nbsp;&lt;/i&gt;&lt;/b&gt;&lt;i&gt;is Vice President of Product Development for Aquascape, a waterfeature design and installation company headquartered in St. Charles, Ill.

With a fair amount of usable biological surface area – both on the outside as well as the inside – it made a good place for bacteria to colonize and grow. The problem, over time is the nooks and crannies that made lava rocks so great, start to clog with debris that eventually turn less effective and can actually cause nitrates (not nitrites) to increase. These nitrates are natural fertilizers that can ultimately feed algae, causing a problem.&lt;/p&gt;&lt;p aria-level="0" aria-posinset="0" aria-setsize="0"&gt;Lava rock also becomes very heavy, which can be a back-breaker when trying to lift out for cleaning or maintenance. And, last but not least, the lava rock starts to break down and eventually has to be replaced. &lt;/p&gt;&lt;p aria-level="0" aria-posinset="0" aria-setsize="0"&gt;There are other options for biological filter media that are&amp;nbsp;made of plastic, like Aquascape BioBalls. &lt;/p&gt;&lt;p aria-level="0" aria-posinset="0" aria-setsize="0"&gt;Aquascape BioBalls provide a textured surface area for beneficial bacteria to colonize and grow.
