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
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!
