I have a 10 year old gunite pool, using bleach for past 12 months as a sanitizer and for shock. Ch is approx 550, drain and refill is not am option as my fill water is approx 350. I have been constantly fighting rising Ph. I lower it to 7.2 and in a few days it is in the 8.0 range. TA is 100.

My questions are:
1. Would it benefit me to raise my TA?
2. How high should I go?
3. Will that help to stabilize my Ph?
4. Will it have any positive or negative effects on my Ch?

Thanks in advance for your help. This forum has been a great asset in helping me enjoy my pool and save money at the same time.
