O.K. Got the polyquat in and about 1/2 cup of DE in the filter after backwashing the already pulled crap. Took a bit to flush but worked. The pool looks a bit clearer, still milky though. I hope it is clean by saturday, my kids are having thier first B-Day/ Swimming party. I let the cleaner do its thing to clean the floor for about 3 hrs today.....Any other suggestions?
