TA and Ph
Three years ago I re-surfaced my pool with Pebble Sheen. The water is very nice but I have to check the TA and add muriatic acid each week. It is a 16500 gallons pool and I add about 1 quart of acid each week to keep the TA in the range of 80 to 120ppm. Is this normal? Do you (with the Pebble Sheen surface) have a simular circumstance?

TA and Ph
Do you have aeration features in your pool such as waterfalls, spillovers, fountains, etc.? Aeration accelerates the outgassing of carbon dioxide and this makes the pH rise. This occur less at lower TA and higher pH so try having the TA at 70 ppm and also try a pH target of 7.7.
