I was wondering if anybody can advise on this issue.
I have a small in-ground fibreglass pool and for some reason I'm having a really hard time keeping the TA and PH stable. I would add the necessary chemicals to get the TA and PH to recommended levels and then it will immediately start dropping again slowly. After about a month the water would be very acidic if I don't do anything.
I've done a lot of searching online, but can't figure out what the cause of this could be.
Can anybody perhaps offer any explanations or suggestions?
