I just ordered a fountain because my wife has wanted one since we have owned the pond.. Our pond is set directly behind our house with is on the edge of town, kind of residential..

Pond is right at a half acre, went with a 1/2 hp with lights.. Will have more info on it next week when it comes in and I get it installed.. It is supposed to move 4200 GPH of water which is a fair amount for a decorative fountain.. I already have an air powered diffuser and a wind powered, but feel a little top water can't hurt..
