Chlorine 6.0
PH 7.4
TA 130
CH 210
CYA 38
Still chasing PH from 7.8 to 7.2 often
TA has dropped from 200 to 130
Will it eventually stabilize ?
Or PH rise normal

Once your TA gets to below 80 ppm the pH rise will slow, but I suspect you have high TA fill water. That will require pH adjustments as you are doing every few days or so, during high evaporation rate season.

A CH of 200+ is good for the fiberglass. No need to raise it.

Remember, you are in charge of changing the Goal settings in Poolmath each time. The app just give you the mid range based on pool type, chlorinating method, etc. Do not blindly go by the app.
