I will give you my experience with rising pH. When I took over the pool, my TA was 130 and I was adding acid every other day. 12 to 24 ozs. I thought I was going to need to buy stock in the MA supplier. I started following the advice listed in the previous post to try and lower my TA. Instead of shooting for some arbitrary number, you need to try and find the "sweet spot." This will be different for every pool. For my pool that ended up being a TA of 70. I have used less than 32 oz since Oct 15. Of course no one has been in the pool for and extended time, so I will be interested in how it plays out during the summer.
Give the advice a try, give it some time, and try to keep some records of how much you are adding (and when) so that you can verify an improvement.
