I have been monitoring my pool water everyday with an approved testing kit and the PH of my pool has been sitting steady at 7.4 for the last three days which is fine, but my total alkalinity has continued to rise everyday. My last three readings are 151, 155, 167. I know looking through this website it says to not worry about lowering the TA just to reach a target number and only lower if you have the risk for scaling or the PH is rising. I have neither of these problems at the moment and since I have a vinyl lined above ground pool, do I need to worry about any of this? I'm nervous the high number is going to cause an unwanted issue for me. I know low total alkalinity can be bad, but what about high in my situation? Any help and information would be appreciated. Thanks.
