So I filled my pool from my city water source. It is an old pool. Concrete bottom with Stainless Steel side panels. My best estimate is that it is 30-35K gallons. My total alkalinity is through the roof from the city water at 300ppm. The only thing I have read on how to lower TA is to dump muriatic acid in to lower both the TA and the PH. Then wait for the PH to come back up (pointing the return jets up to the surface) and then dump more muriatic acid in, repeat endlessly. or so it seems.
So I made a TA reading at 300ppm. Dumped in two gallons of muriatic acid. Next day it was a high 290ppm (29 drops titrant).
Based on that I would need to repeat this process 14 or so more times to get it down to 150ppm. My pool will be closed by the time I get that done and something about adding 30 gallons of muriatic acid to my pool doesn't sound safe or helpful.
Any ideas on what I can do to get my TA down?
