My plaster pool (one waterfall) is 3.5 years old. Following TFP I have had very few issues keeping a clear pool and for the most part, the pool is in fact trouble free. I test the water often and it is always in balance. My question is about low TA.
Over time my PH will creep up to 8.0 and I add acid. Usually need to add acid every 10-14 days. The pool builder told me to expect to add acid for a year and then it should level off. It hasnt. My TA will drop into the high 20's to low 30's. On several occasions I have added a lot of baking soda to get the TA up to a good level, and it will slowly drop back down into the low 30's. The pool seems to like this level of TA. CH is a little high in my water around 350 or so. With the low TA, high CH I can easily keep the pool balanced by adjusting PH. I run my pool year round as it has a connected spa.
I guess my question is should I just go with the low TA numbers and keep adding acid or should I go crazy and add a lot of baking soda and try to get the level up. Do some pools just have their own "balance"? My testing chemicals are fresh and this is how the pool has acted for 3 years.
