Waterfall Foam expands to fill voids between the rocks and liner, diverting water over the top of the stones. It simplifies waterfall construction and is easier to use than mortar. The foam will not crack in freezing temperatures. The black color of the foam will blend into the waterfall setting by looking like a dark part of stone or a shadow.
Waterfall Foam will not harm fish. It will be cured in 20 minutes and can be easily removed if necessary.
Waterfall Foam will gradually expand after dispensing. Be careful not to over apply. Excessive foam, once cured, can be peeled away. Waterfall Foam is designed to divert 99% of moving water. This product will not provide a 100% water tight seal.
Most pondkeepers know that the best way to ensure clear pond water is with an ultraviolet sterilizer. Some often overlooked factors are what to do when the UV light is not doing the job anymore. Usually, this is a simple as an old lamp. Depending on the brand, UV lamps should generally be replaced about every 12-15 months of use.
