I have an above 16X48" Ultra Frame pool. I am looking at a few sand filter pumps, I have been using the cartridge
pump/filter that came with it, which is the intex 635T. I believe it is a 1500GPH pump. I am looking at the Intex 2100GPH
Intex 2800GPH and the Intex 3000GPH. My pool is only 5061 gallons. What would be best? I am looking on Ebay. There
is a Intex 3000 GPH that is used and they claim it was only used for a month. I could get it at a pretty good price. It is
a 1 HP the others are a .5 HP and a .75 HP.
