So you are thinking of deactivating your SWG and going back to manually adding the chlorine? I guess if your system is defective or broken in some way there would be a plus to manually adding chlorine in that you would know how much you are puttng in? - the CONS would be that you are purchasing chlorine and manually adding chlorine vs a system that automatically generates it and you don't have to purchase anything extra ......
I know the process of MA, to bring ta and ph down. Then one aerate the pool to bring ph back up. The problem is that if I keep aerating the pool the ph will go through the roof and then ta starts to go up. If I turn the jets down the ph still goes due to temp and swg out gasing. Ta will also go up since they seem linked. Not sure what to do.
TA does not go up from aeration. It only goes up if your use a chemical to raise your PH. As the TA goes down, which it will if you continue adding acid and don't add any soda ash, borax, or baking soda, you will eventually get to a point where the PH will stabilize right around 7.7 or 7.8 with the TA around 50 or 60.
However, TA will go up if you have to add any replacement water. Hopefully, during most of the summer it will be humid enough that the rate of evaporation will be low, and you won't have to add very much replacement water.
Some SWCG pools will always have a rising pH issue. Even if you have all of the test results in line with the recommendations on this site. You may have one of those pools. I also have one of them. The only solution is to find a ways to automatically add acid. It does not have to be a closed loop system, it can be a s simple as a pump on a timer added a fixed amount of acid each day.
