Been fighting a cloudy pool for awhile. When nearly 2 weeks of slamming didn't help, I deep cleaned the sand filter. Before I could get back on it though, I left town and my pool went green, and I ended up having to change about 40% of my water due to a now high CYA level (long story short, someone put dichlor in my pool while I was gone).
Been running at SLAM level now for a few days, and the pool is still cloudy. So I just performed the "add DE to a sand filter" procedure outlined in pool school (hadn't readded since the water change). In under a minute I watched the DE come right back out of the returns. 2 cups used to raise my psi by a pound, and now it's only added about half that.
Also, I performed the deep clean of my sand filter a few weeks ago, and noticed my filter is running consistently at 8 psi (down from the 10-12 I used to run at). Had to add sand while I was in there too because the level was low.
Any thoughts on the low-pressure/DE coming out of my returns/perpetually cloudy pool? Spider gasket maybe?
