I've noticed that my PH seems to always rise to about 7.8 and then it seems to level off. The water is still a bit cold, but the kids have been playing in it on the really warm sunny days, but their hasn't been a whole lot of splashing and I don't keep my return jets pointed toward the surface so their really isn't much if any aeration going on. It seems that when I check my PH everyday, it is at 7.8. I was adding a bit of MA to bring it down to 7.5 each day, but it always seems to jump back up to 7.8 within a day or two. When I don't add the MA to make the small adjustment, it just stays at 7.8.
Is this something that is normal? Should I just not bother making the minor adjustment unless it rises higher then 7.8?
