Thanks.

Still cloudy.

My water results now are:

FC 11
CC .5
PH 7.2
TA 140
CH 350 ? sample never turned blue, went clear at about 350
CYA 50
VOL 36,000 gal

I added another 2.5 lbs of Borax a couple of hours ago, but it didn't really move the needle on PH. I'll check it again in the morning and if it's still down I'll add another couple of pounds, trying to get to the 7.5 recommended in the sticky for the zero CYA startup condition.

It's almost dark, I'm not going to add any chlorine and see what it drops to by morning.

Any thoughts?
