I have an ~15 gallon water feature goldfish pond in my yard, and to keep it clean I run an extension cord with an indoor tank filter that sits on the rim.

It works real well but it's impractical to run AC for a pump, so I have been looking online but am getting nowhere.

What I would like is a solar model. I have a sunny spot approx. 15' away and a remote solar panel / pump would be best.

Failing that a model placed near the water feature with a replaceable lead acid battery that can be used with a spare that is charged off line.

Anyone have a similar problrm theyvhave solved?
