Evening report:
FC 2.3
CC 0.4 (tested twice to confirm both FC and CC)
pH 7.2 / 7.4
TA 190
After pulling the water sample, I added 1 pint acid, brushed the walls and bottom. Visibility unchanged over past two days (about 2'), then added 6 gallons of bleach. Still have scattering of light foam on the surface.

Since the CC was 0.4, I should up the bleach according to your post earlier today. How much?

Do you have any guess at the timeframe until this treatment clears the water up - days weeks?

I have questions about maintaining the pool with CYA so high (somewhere way over 100), but I'll wait until I get to that point before asking. Thanks!
