We have a Summer Escapes (General Foam Co from Walmart) 18x48 pool. It hold a little over 6000g. After fiddling with the existing filter all summer, I am upgrading to a sand filter this spring before I open it. I really wanted to work with a local pool company until I'm a little more sure of myself, so I have 2 options. The first is a 1.5 hp Pentair with a 18 in sand filter. I'm really afraid that this is just overkill. The other option is a 3/4 hp Hayward with a 14 in sand filter. The pool supplier told me this one was created to meet the needs of a smaller pool and all the fittings come with it. This one would turn over our entire pool in a little less than 3 hours and is the one I am leaning toward. I did ask if I decided to get a 24" pool if this one would work with it and was told that it would. I'm adding the Intex SWG while I'm upgrading. According to both companies, the filter is matched correctly with the pump.
OK, so in my shoes, which one would you go with, the Hayward system or the Pentair? I have read so much information lately I'm not even sure where to begin anymore!
