Thanks. I recently moved the pH to 7.2 in order to reduce the TA. I will follow your suggestion on the pH and TA.W,
Most saltwater pools like their pH to be about 7.8.. I suggest that you quit trying to reduce it to 7.2. I would not drop it below 7.6..
As far as TA goes.. as long at your TA does not drop below 50 ppm then I would not worry about it.
When your pH gets to 8.0 then drop it back to 7.6.. Over time your TA will come down.
Thanks,
Jim R.
