Normally the curing would produce Calcium Hydroxide and would not raise the TA. The TA would only rise if Calcium Carbonate was released into the pool. After curing, this would be considered "corrosion" of the pool surface. I'm not sure if it is normal for this to occur during the curing process. Did your pool contractor say that it was normal not only for CH to rise, but for TA to rise during curing or do you know if that's true from any other source?

It would be great, after we have this all figured out, to put together a simple flow chart that people can follow that would explain the normal processes they can expect in their pools. New plaster/gunite pool in first year -- rising CH (and TA?) and especially pH. TA > 80 and/or pH < 7.4 and/or lots of aeration -- rise in pH. Etc. Some would just be explanatory items while others could have solutions.
