PH levels

[Big Splash]

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

It looks ok I'm running my robot now to make sure the water is turning but looks ok still a little cloudy in the deep end. So why do I want my CC to be 0. Just wondering. Also glad to hear about the PH made me a little nervous.

The cloudiness could be just dead algae not yet all filtered out. It be a good idea to run the pump all night. Check if the filter pressure has increased on your gauge. Backwash if need be. Turn off your SWG while shocking so you can getting a reading of the FC loss.

Why do I want my CC to be 0? The short answer is... if it's giving a reading more than zero, that would indicate there's some type of nasty stuff in your pool that needs to be killed.

Search for "combined chlorine" or "chloramines" if you're interested in the long answer.

Let us know how you make out.

So pool looks a little better still cloudy in the deep end but better.

I tested it 4:30 pm yesterday before I left for work FC was 14 cc was 0 so I had my wife add half a bottle about 60oz of bleach at 7:30.

This morning FC was 13.2 cc was 0.

Should I just see what happens the next 24 to 48 hrs?

I'd keep up the shock level until it all clears. It could take a few days for your filter to get it all. Keep running your cleaner and brush the pool to stir all the stuff off the bottom. That way, it'll find it's way into the filter faster.
