    High PH after adding bleach

    I'm in the process of shocking and I added 16 ppm FC, 3-182 oz jugs and 3-96 oz jugs of 6%. My PH was ~7.4 before adding the bleach and now it went to ~8.2 about an hour of so after adding the bleach. I did see another topic "Expected pH to rise after shocking...but it didn't" which kind of discusses this but I was wondering if I just let it ride or adjust the PH? If I need to adjust it should I wait a day before I add more bleach and adjust at that level?

    Thanks

    PH will usually read false high when the FC is above 10. Disregard, and don't try to adjust PH when the FC is above 10.

    Re: High PH after adding bleach

    You're right, I ignored it and it went away...yea! I'm back to ~7.4. However I have 0 FC and 0 CC at the end of the day after being at 16 FC the previous evening. CYA is ~40-45 (best I can read it) and TA is 90. I'm trying to shock but leaving for work at 5:15 of a morning I just don't have the motivation to test of a morning. Do I need to be more persistent, wait till the weekend, or what to get chlorine usage to a normal level?

    Be more persistant.

    I'm sorry my friend but to make progress you really should make the effort to add bleach in the morning too - or it's going to be a long week....

    If you let the FC drop to 0 the algae can just grow right back, and then you are just wasting bleach. So either add it at least twice a day or wait till the weekend and then do hourly bleach additions if necessary, even then you might not be able to tackle it in 2 days....

    Sorry wish I had better news for ya.

    Re: High PH after adding bleach

    Yep, I was afraid that was the answer. The other problem is we'll be out of town this weekend and next so the FC would just go away while we're gone for a few days. As for keeping FC in the pool while you're away what do most folks do? Get a SWG, Liquidator, etc? I have a chlorinator on the return line that uses tabs but I just now am getting rid of the stabilizer and don't want to go there again.
    Thanks

    I think an SWG is in your future.
