Awhile back I bought a Smartpond pump for a small water feature on my patio. On the info. card they said if I registered the pump they would send me a filter bag for it. I did so, and they sent me this. The bag is 15" X 15", and my pump is about the size of a softball. Perhaps it was for a larger unit, in any case not practical for me. Perhaps one of you with a real pond and a big *** pump could make use of it. The mesh is basically 1/16th" X 1/16th".
Should one or fewer apply, there you go. If by chance more, I'll draw a name.
