I started the year with a Ph of 7.2., so I aerated for a week and brought it up to 7.6. I was told then that should watch and make sure the Ph doesn't go any higher as it has a tendency to rise with SWG pools. Well over the last few weeks I've slowly watched the Ph fall, and it's now down to 7.0.
So first, why does it keep falling? Is this normal? Am I doing something wrong?
Second how important is it to bring it back up?
Lastly, if I do need to bring it up, is aerating my only option? I don't really want my TA to get much higher.
(P.S. I know my FC is a little high, I'm just coming down off a shock and I'm trying to get my generator dialled in again)
