A warning to those that may be considering purchasing a product made by Atlantic Water Gardens. DON'T do it. I bought a can of their waterfalls foam for $16.00 dollars. Not a huge sum but not cheap either. The can was defective so I went on line to find a number to call. I made two calls the first I left a voice mail but never received an answer. The second was to a customer service manager. After explaining the problem his solution was to take it back to the store. Now why didn't I think of that! Because to take it back, would have involved over 40 miles of driving. I told him that and his reply was simply silence. I'm glad I learned my lesson on something small and not a skimmer. I can imagine them telling me to dig a skimmer out and take it back because a minor problem that could be solved if they simply mailed out a part.
