    Have the test kit, new results, need advice...

    I had terrible algae, got the FC up to 10, it seems gone, but pool is so cloudy.... I received my test kit in the mail yesterday, I have the new test results, I have added 2 lbs CYA in a sock:

    CYA was at below 20.
    FC = 7
    CC = 1.5
    TC = 8.5
    TA = 60
    PH = 6.8
    CH = 230

    Should I do more?

    Thanks!

    Your pH is too low. In fact, it may be much lower than 6.8 because that's as low as the tester reads. It could be 5-something! So treat it with Borax or Soda Ash to get it up into the 7.2>7.8 range.

    Then resume the shock process because that CC level is still too high. Use the calculated CYA level you should be at to determine the FC level. http://www.poolcalculator.com/ can give you an estimate if you enter your pool size and scroll down to Effects of Adding Chemicals.

    OK. oops, out of Borax. Would Arm & Hammer baking soda be good?

    Thanks!

    No. Baking Soda has very little effect on pH, but a huge effect on TA.

    Will do, the CYA - still a lot of it in the sock, I guess it takes a while?

    Thanks again.

    Re: Have the test kit, new results, need advice...

    Retested today after adding 5 lbs Borax yesterday and 3.5 lbs CYA the day before.

    CYA = less than 20 (it hasn't dissolved yet, but black dot finally disappeared)
    FC = 4
    CC = 1
    TC = 5
    TA = 70
    pH = 7.2

    Water is still cloudy, no change, but no visible algae now. Is chlorine ok? Should I shock again?

    Re: Have the test kit, new results, need advice...

    You haven't finished the shock process yet. There are 3 criteria, and you haven't met at least 2 of them. You follow the shock process until:
    1) CC<.5
    2) <1 ppm FC loss overnight
    3) The pool is clear.
    Sounds like you need to reread the shock process, which is conveniently linked to in my signature.

    Re: Have the test kit, new results, need advice...

    I remember one other question about the process. Since the CYA level is changing so slowly due to the fact that it is taking so long to dissolve - it's there in the skimmer still, and I've added the Borax, I'm trying not to vaccum and backwash since I'll be losing all those chemicals to waster. But should I backwash anyway in the midst of this procedure if the level reaches 20? That's when I usually do it.

    Re: Have the test kit, new results, need advice...

    That's why it's better to add the CYA to the pool via a sock in front of a return, it doesn't clog the filters, and won't be backwashed out if you backwash before it is dissolved.

    You should backwash when the pressure goes up 25% of the clean pressure.
