anyway checkin out prices on the net fer above ground pools. i found a pool thats 22x10x4H for the same price as a 8x3x2. seeing as how thats eventually what iwant(a 6000+gallon pond) i may as well go for this. anyway decided to start saving for it. i was thinking pool sand filter, large sump(using a stock trough) and possibly biotower or some other weird super de nitrofying process. and of course uv filter. anyway does anyone have tips for heating? do i need to improve my filtration?
