I appreciate all the great responses, but I was wondering if I could use something better than an Intex brand filter(I'm tired of rinsing the paper filters 3x week, and then replacing them after that, this is the only way I get good suction at my skimmer, and good flow out my output into the pool). I see lots of sand, cartridge, DE filters for sale on craigslist. Also, can I use an IG style filter for my AG pool, or would I be better off with an AG type? Thanks!
