Yeah I still have the same problem. It's very aggravating. I didn't backwash for almost the past month and it didn't change a thing, well I shouldn't say that after I backwashed the stuff at the bottom of the pool was just lighter in color

If you don't mind putting a panty hose on your return it does catch the dust. Just looks ugly and also it doesn't allow my pool to whirlpool when the filter is running then the real stuff that should collect in the middle for easier vacuuming doesn't collect.
