Well I am servicing my own inground pool (~30,000 gal) for the first time this year. Following the TFP method and got the pool up and running, SLAMed it and the water beautiful. TA at ~110, FC 7, CYA 60 ...
except..
My pH is literally off the charts >8.2
We had the pool refurbished (piping, deck, pebblesheen, etc) last year and it was only open about 30 days before the winter close. Had the pool company close it. Fast forward to this year, I assume the new plaster spiked my pH and when I did the initial test I guess the pool was not well mixed with the added water. I did the pH test a lot earlier than the other standard tests, won't do that again.
SLAM worked well regardless.
But my pH is staying above the 8.2 indicator. Already added 2 gal of ~25% acid, and half a gal of 34.6%. Literally no impact on pH.
Is my path here to keep adding acid 1/3 gal of 34.6% at a time (44 oz moves 8.2 to 7.5) until i see an impact and can calculate the required amount? Just checking my approach with those more knowledgeable. Any other causes that could be driving it up I should check for?
Thanks
