We're just about to wrap up our first full summer with our pool. It was completed in the middle of summer last year, so this is our first full summer with me handling all of the maintenance besides open/close. Just now starting to experience some water clarity headaches so I'm hoping to lean on the expertise here. Pool is 18' x 36' with a max depth of 6'6". We have cartridge filters with a heater and ozone system. Right now my biggest issue is white specks floating throughout the pool, even after I've cleaned the filters. I took them out three straight days and hosed them off but they go right back to reading dirty on the gauge again. Seems too early to need to replace them, but what do I know?!
