We have a new 18'x52" Intex Ultra frame, 6981 gal volume. I wanted a DE filter, and saw one on craigslist for $75.00 advertised as a sand filter, but label said DE, but no size or model number was shown.
Drove 2 hrs to look at it. Complete pkg. was used for one year, like brand new with a 2hp pump, valve and chlorinator. So I bought it. Upon returning home, researched. As it turns out, it is waaay big.
It is a hayward Pro-grid 4820, advertised to turnover 7200GPH. Am I crazy to try and use this? All input is appreciated.
