What would make PH go down then? We haven't even swum much this year yet. It just seems to gradually go down all by itself. ???
H is convinced it's the bleach which I guess makes some sense since that's all we ever put into the pool... but... if bleach is ph neutral it can't be the bleach, correct?
We have a cold pool (right now it's about 60), it rarely gets above 75 even when it's hot out. The Taylor wheel says we're supposed to run ph high due to temperature (although this is all from memory, dad took back his Taylor kit with the wheel so I can't reference it). I raised it to 7.7 a few weeks ago, and it's down to 7.3 as of 3 days ago.
Yes, there has been some rain and I drained about a foot down to place a patch about a week ago. Fill water ph is 7.8-8.0 (or should be, according to the water bureau's website - they add sodium hydroxide to increase ph), so that can't be the problem either.
I have no CC, I dose to target (7) when it gets below 4 (daily or every other day if it's cloudy), TA is 80, CH 90, CYA 35. No one is swimming yet (kids gone till Friday).
Ideas?
I know I shouldn't hijack this thread but it's got a good title that will be searchable. Mods, move if needed or I can just repost.
