PH levels

[southjerseypool]

I have a 22 x 39 mountain shape so not 100% sure on total gallons. 8 ft deep end I guess 3 ft low end. I've always guessed 27k gal. Sand filter, liner 1 hp SWCG

Head south down Rt130 to Wally World for some bleach. Don't stop at Riverton, if you get to Leisles... you went to far

At 27,000 gal, 407oz (about 3 1/3 jugs) of the 8.25% will add 10FC to get you to shock level. Keep it over 15FC (but not over 20FC) until your CC reading is zero, the pool is clear, and you loose less than 1FC overnight.

Thanks I just added 4 of the 121 gal 8.25% I will add another 4 tonight. Thanks again for the help.

Retest in about an hour and before adding more. You might not need an additional dose and you could damage you liner and equipment with to much.

Just re tested. See below.. Now what test again when?

FC 19.2
CC 0
PH 8.0

No, don't retest until this evening.

Your CC is 0. That's good. How does the pool look? Your pH reading will be artificially high at anything above 10FC. So, don't worry about that for now. As Watermon said, retest at dusk. If your reading is less than 15FC, top off using the same math as before. That is... if 407ozs of the 8.25% added 10FC, then 40.7ozs will add about 1FC. Be sure the pump is on when adding bleach. Retest again tomorrow morning. You ideally want to have no more than 1 FC loss overnight to know your shock is successful.

Good luck
