I’m a new pool owner (old pool, new owner ). I bought a house last August and maintained the pool for about a month before I closed it for the winter. I’ve been educating myself on the pool maintainance subject for a while to make sure I know what I’m doing for the coming pool season.
One question that I’m not crystal clear is the order of adjustment for TA and PH. I understand what they are and the relationship between them and read as much as I could but still there doesn’t seem to be a consensus on this topic. There are several posting on this subject in this forum but that seem to answer a specific situation rather than a general approach.
Here are my thoughts:
TA low, PH off – adjust PH first and then “fix” it in the range by brining TA up. Problem with this could be troubles adjusting PH since it might go up and down wildly since TA is low. Alternative would be to bring TA to the range, then adjust PH. Problem with that it could be difficult to adjust PH since it would be stabilized by TA being in proper range.
TA high, PH off – adjust TA down first to allow for PH to be adjusted, adjust PH then. This seems to be logical, since it would be very difficult to adjust PH if TA is too high, so it seems like there is no choice here. Again I still see the problem with adjusting PH if TA is normal as in case above.
I’m somewhat inclined to adjust TA first and then change PH if adjusting PH is not too difficult when TA is ok. Opinions on this forum and internet in general vary, but I would love to hear some pros and cons for both cases.
P.S. I know that chemicals for adjusting might affect both, but that can be accounted for. For the sake of discussion let assume that adjustments are 100% independent.
