I'm in the process of constructing a natural swimming pond. The key requirement is that half the surface area be plant life that filters the water. so, the desgn I have in mind is to run a pump from the pool water to the surrounding plants. the pump i am considering is a dc, 24 v, 3 amp, 72 watt 3gpm, shurflo 2088. now i am searching for the solar panel and am overwhelmed a little by the choices out there. the prices seem to vary a bit as well. any input appreciated.
