6/8/2010 – We bought 2 preformed ponds and joined them with a 6 inch pvc tube so the fish can swim from one pond to another. I sealed them with aquarium silicone and they held during the summer, but then during the winter they became stiff or something and came unglued. my water leaked out around the pipe. I want to know if the silicone will seal this if I take off the existing silicone and will make it through the winter here in Utah. Thanks
Response From TJB-INC: Yes, it should hold up much better because it stays flexible when cold.

Thanks, Sande
Response From TJB-INC: Do your urn not hold water? If you need to waterproof the entire inside of the urn, (I would get a new urn) you can use waterproofing paint from a local home center. You will have to prep the urn's surface to accept the paint and then allow it to dry before using it in your pond. If you only have a leaky seam or small holes, then our Fish Safe Black Silicone will work. I guess you could "paint" the entire inside of the urn with silicone but that would be expensive.

6/15/2009 – Can I use the Silicon to attach stone, on the inside of my pond 13"x8"stone strips, to the Rubber Liner? The wall of the 5' round pond will be supported by a rebar enforced concrete wall.
Response From TJB-INC: Yes. THe adhesive has a rating of 10 out of 10 for adhesion. Use it where ever you need to attach two items together. Allow to dry before adding water. (24 hrs)
