My pool is a bit of an oddball and even one of the more experienced members here remarked that my pH was amazingly stable for a new pool. For what it's worth, my pool stayed in gunite for 3 months prior to interior finishing (not MY choice...). I don't know for sure if that's relevant, but it seems to be the only explanation.

My Pebblesheen is nearly 3 months old and I'm only in my 3rd gallon of muriatic acid. In fact, my pH seems almost stuck at 7.5. Once, early on, I added enough muriatic acid to drop it to 7.2 but within just a day or 2 it was right back at 7.5.

My TA is just 80 and I run a waterfall 12 hours a day. SWG just operational for the last 2-1/2 weeks. Have added about 5 cups muriatic acid since the startup of the SWG. Last addition was 9 days ago and I'm about to add some today, as my pH still reads 7.5 but is taking on a bit of a pinkish overtone.
