Been dealing with this problem for a few days. About 10 days ago, did my testing and found the CYA was very low so added stablizer to bring it up to about 25 - our second year, don't think it's ever been over 25.
Then the rains came. It's been very wet in central NC. pH got high at 8. The pool started to lose it's sparkle and couldn't see bottom of deep end. I vacuumed several times to no avail. I started shocking to 12 and it passed the OCLT for two nights. I did alot of brushing. It has cleared up somewhat but the deep end remains a bit cloudy and the sparkle is not there. And the brownish dirt remains. The shallow end looks good until it is brushed and then I can see that the brownish stuff is still there. I brought the pH down to 7.4. Thought I'd leave it there until I talked to TFP.
Here's my testing from this morning:
FC - 12
CC - 0
TC - 12
pH - 7.4
TA - 80
CH - 160
CYA - 25
After reading TFP about the problem of cloudiness and brownish dust on the floor of the pool, I can think of two things to do - vacuum to waste &/or add DE to filter. Before I try these things, is there anything I'm missing chemical-wise? Should I continue to shock? If so, after bringing FC down to 3, will the pool be safe to swim in even though still cloudy? Grandson is getting anxious! Thanking you in advance! Billie
