I am new to the forum and hope you folks can help.
I have 16K gunnite pool. I can't seem to balance the water. Here is the problem.
No matter how hard I try, I can't seem to balance the PH without increasing the TA.
For example, I had a PH of 7.0, When I added enough Borax to raise the PH to 7.5, it also raises the TA to about 180.
Another example. I had a yellow mustard problem and the pool dude recommended a chemical called "Yellow Out". This product is most effective at a PH of 8.0 so he calculated the amount of soda ash to add to my pool so to bring the PH to 8.0. When I added that amount, my PH rose from 7.1 to 7.5, but my TA went off the charts at 250.
Today, I added muriatic acid to lower the TA and it is now at 150, but my PH dropped to 7.0
Now the question....from what I read, Borax was supposed to ONLY raise your PH...not your TA.
I thought by adding muriatic acid in one spot in the deep in of the pool, it would ONLY lower my TA...not my PH.
Is there any way I can lower or raise one of the other without it effecting the other.....
