I opened pool at 100 TA, it has lowered to 80 since due to acid. I added borates 50 ppm week or two ago, now I am reading 100 ppm again since last test before added borates.


Didn’t expect TA to rise at all. Have a swig so normally only thing I am adding is MA to control pH, which is main reason I added borates. I keep my CYA at 50.

Borates add alkalinity, but not 20 ppm for 50 ppm borates.
Testing variations is most of it.

It s discussed on the pH/TA video on TFP TV.
