Last summer I upgraded to a quad cartridge filter system. Definitely did it's job. My issue is when I vacuum the pool floor, the dirt particles come right back into the pool from the return jets. The water looks great, but there is all this fine particle Crud on the bottom. So I hook up the vacuum, start sweeping, and then all that dirt comes right back after taking a joy ride through my pool plumbing system. Next thing I know my water looks cloudy and like junk. Any idea why, or more importantly, how to stop this from happening?
