Thanks everyone for the amazing replies. This forum is fantastic. Now I’m off to read about CSI…

Ok, I’ll try the “add acid at 8.2 to bring it down to 7.8” method and see how quickly my TA comes down over a couple of weeks. Does the “add acid to bring it down to 7.2, then aerate and repeat” method work more quickly too bring down TA?

OK then, I can do that! Fascinating reading, thank you. I need to scour this site more, obviously! So it’s OK to not keep the pH within the “traditional” 7.2-7.6 range? Presumably keeping it around 7.8 will keep my pH rise more manageable. I expect my TA will take some time to come down by...

Thanks very much for the reply. No, I don’t have any water features or spillovers. I recently added a load of buffer to raise TA (at the suggestion of a pool shop, argh). Previously it was around 45, but I was still having problems with pH increasing rapidly. I presume I can just keep adding...

I’ve been in my current house for a bit over a year. The pool was built maybe 2-3 years ago. In all the time I’ve had this pool, the pH level rises extremely quickly, while very other metric seems fine. I have a chlorinator, and chlorine levels are fine. Alkalinity is 120. To keep pH stable at...
