Adding borax wasn't bad and ph rebalanced out nicely after the acid.
(Just remember - do as you oughta - add acid to water )
before starting the TA was ballpark correct, about 80-100 ppm. Couple of questions..
1) Does the TA chemistry change once the borates are in play? (I guess that the acid add could reduce TA as it neutralized the sodium bicarb that was eaten up over and above the borax buffer ph adjustment?)
2) how should Alkalinity adjustments be done in conjunction with the borate adjustments in the future?
My thoughts for it being a pain in the a** to get the TA corrected after borate add would be the ph adjustment step of the acid eating up the already too low sodium bicarb in the pool, effectively eliminating it as a potential buffering agent.
Thanks for reading.
