Acid use

[H-12 1/2 Mike]

My target ph is 7.65 but recently I have been adding more acid (7 oz per day vs 7 oz per week). I use liquid chlorine 8.75% at about 44 oz per day to keep the 16k gunite 5ppm. I am adding city water at the rate of 1" every 6 days. The TA is stable at 100. Is this normal?

Normal varies from pool to pool. If your fill water has fairly high TA, then your situation makes total sense. If your fill water TA is near zero, then something strange is going on.
