Update -- Pool is still VERY cloudy - but water is still blue. I can barely see third step in deep end.

Only thing done since last night was my husband did some more blind vacuuming to waste - and we added some water to the pool. No chemicals have been added. Chlorinator is still off. Readings as of 7 pm -- PH 6.8 Chlorine 2-4 Alkaline 80 -- I broke down and bought the polyquat at the pool store, after verifying it was 60% and matched chemical names to your web page.
I need to get this pool clear -- I'm very tempted to use the Clarifier I have on hand -- but I will wait for you to respond.

I hesitate to add the bleach - with the chlorine still at 2-4. I will put the cup of polyquat in tomorrow morning.
