Thanks guys, the reason for the posting (kinda cross-posting sorry) is that I was getting paranoid I wasn't filtering as the pool although crystal clear showed alot of small debris once I went underwater with goggles on. I'd thought running the "overkill" pump and filter for 4 hours in a 5500 gallon AG pool would eliminate all debris.

I may backwash today just to look, and might open her up for a quick peek.
