After many posts, many threads, and too many questions I have decided to go with a cartridge filter set up. I've shifted from sand to cartridge for a couple of reasons. First, water restrictions in So. California are only going to get tighter. Seems to make more sense as I will not have to backwash the filter. Second, it appears I can get more gpm flow with the same size pump if I go with a cartridge filter instead of a sand filter. Contemplating a
Pentair 1-1/2 HP, 2-speed motor with 150 sqft cartridge.
(PNCC01500F2160). Does that seem to be enough overkill for my little Intex or would anyone recommend I jump up to a 200 sqft or even a 240 sqft cartridge? (Looking at the specs, I think they run with the same motor) I'm thinking that even the 150 sqft set up will let me upgrade to a 16 x 32 Intex if I decide to do that in the future. How do my logic and my calculations sound?
