Yep, keep maintaining shock level.doublewide6 said:I retested with a new sample .5 FC 5 CC
So I guess I will keep adding bleach.
Generally we say it is safe to swim if FC is between min and shock level based on CYA, water is clear and CC is .5 or less.doublewide6 said:Good News 9:00AM FC 14.5 CC 0
When can we safely swim in the pool?
No. If it was 7.6 yesterday and you added nothing to lower it (bleach won't do it) then it is a testing error either today or yesterday.PH has dropped to 6.8 - is this caused by the bleach?
Yes. Your addition of CYA lowers the pH in your 20k pool by about .4. Not enough to completely account for your .7 loss you report but probably close enough.So can cya lower PH?
