I want to change from sand to cartridge due to too much sand getting in the pool. It's a new 18x33, 54". I have a few questions. I'm currently running a Hayward Power Flo LX 1.0 HP piped up with 1.5" PVC.
1) How many sq. feet of cleaning surface do I need? I want near-overkill here and don't want to wish I had gotten something bigger.
2) Can an in-ground 4-cartridge system work? Something like the Hayward C3030 or a similar Pentair? The input/output fittings are on the same side of the canister on those and that situation works best for my pump/filter location.
3) If I need to stick to single cartridge filter cannister system, what make/model/sq. footage would you recommend?
Thanks in advance for some advice here.
