    Can't seem to get my pH up and my TA down....Help

    Hello all,

    This is my second season using the BBB method. I really thought I had it down and everything worked great last year. I opened the pool about 3 weeks ago and have been fighting low pH and high TA ever since.

    Inground with liner - 15,299 gallon

    Current readings:
    pH - 6.8
    TA - 180
    FC - 5

    My chlorine has been holding perfect and the water is crystal clear. According to the Pool Calc they stated to add 304 oz of Borax. I did this a couple days ago and I am still getting the same reading. I have an auto cover so no rain is getting into the pool. It is supposed to be sunny tomorrow so I am going to open the cover and point the returns up to aerate.

    Any other suggestions? I know adding borax should raise the pH and not raise TA, but will that lower my TA?

    Thanks for the help!

    The best way to solve your problem is aeration. build a cheap fountain, toss the kids in the pool, etc. Get some frothing and churning going on. It may take a day or two but your pH will come up and your TA will go down.

    Thanks for the suggestion. Sun just came out and I will hook up the fountain and turn my returns up toward the surface.

    Here's a link to the acid/aeration article in Pool School for lowering TA:

    You're done SLAMing when:
    1)You lose 1ppm or less FC overnight, & 2)You have .5ppm CC's or less, & 3)your water is clear.

    Welcome to the forum
    Thanks Butterfly! I actually turned my returns straight up to break the surface and that has been running for about 5 hours. I just tested and my pH has already risen to 7.2 from 6.8. Also, my TA has dropped to 120. Going to check in a few hours again to see where it's at and then go from there. I think if I get the pH up a little more I should be good to go. FC is staying right where it needs to be.
