Here's an update...
I lost about 6 ppm of chlorine overnight and the ph remained at 7.2
The water is MUCH clearer (can see the drains in the 8' end and the liner pattern) but still somewhat cloudy.

Each jug of 6% bleach raises my cl by 2 ppm, so I added 3 jugs and I'll check it again later today. The pool is in full sunlight for the rest of the day.

I should have mentioned that all the heavy debris has been vacuumed out (to waste) and I brushed the walls several times right after we opened a couple weeks ago. The only sediment on the bottom is the minimal stuff that will collect around the seams opposite the return jets overnight. Should I still vac to waste?

Looking ahead to the aeration part...we've got a couple fountains at the deep end. We usually only turn them on when the kids are swimming. But if I leave them on for a good portion of the day, that will aerate and raise the ph?

Thanks,
Bill
