Hi all, my PH is at 7.2 and TA at 80. Is this ok or should I add borax to increase to 7.5? I don't have any kind of aeration device.will my PH eventually start increasing(and how much) or does it stay the same all the time? If I just keep it at 7.2 will it increase in its own and being at 7.2 is this ok? Does TA fluctuate? Thank you all as my pool has been crystal clear thanks to TFP. Thanks again
