    Chemical rules?

    I have been testing my water at least every 2 days. Today's reading;

    FC 1.0 ppm
    CC 1.0 ppm
    pH 7.9 ppm
    TA 70 ppm
    CH 270 ppm

    According to the pool calculator I need to add 96 oz of Bleach to raise the FC & CC and 14 oz of Muriatic Acid to bring down the pH.
    My question is how long should you wait before adding MA after adding the Bleach? With a SWG I understand it's OK to leave the cell on when adding bleach but I have read that it is recommended to turn off the cell when adding MA. If I do, then for how long?
    I'm slowing trying to process all this information. I have been keeping a log since day of getting my K-2006 test kit.

    I think it was just a typo, but CC is something you do not want to raise. Perhaps you meant TC, Total Chlorine. CC is something that you do not want to read above 0.5 or it is time to shock.

    See, I learn something new all the time. I will make a note of that about the CC.

    How long should I wait to add MA after adding Bleach? Or should I just shock the pool?

    As long as you are pouring in front of a return jet with the pump running you don't need to wait very long, a minute or two. Likewise there is no need to turn the SWG off when adding that way. The only time you need to turn the SWG off is when adding salt you turn the SWG off for 24 hours.

    Your FC level is too low. You may need to turn up the percentage setting on your SWG. And if CC is still above 0.5 tomorrow you need to shock the pool.

    Thanks Jasoni, I'll add the bleach and MA today and if the CC is still low tomorrow, I'll shock it.
    Now when shocking it, do I need to turn the cell off? Again all this info is being process so hopefully I won't have to ask it again.

    You don't need to turn the SWG off when shocking, but you do need to turn it off when doing an overnight FC loss test. Having it on when shocking doesn't help very much, so I tend to turn it off.
