You probably won't get red eyes from having adequate levels of chlorine, but you might from Ph. I find my eyes getting irritated by anything over about 7.6.
The PH and TA work hand in hand. Lets get your pump fixed and we will work on all of your levels.
The new plaster will push that PH up and fast. MA is your best friend for a while.
I think there may be some disconnect here. The pump is fine but there might be a leak somewhere in the pool that we are trying to diagnose. I will be turning the pump off 48 hours starting tonight (not before my daily acid and chlorine add mind you) and will mark the water levels to see how much we lose. I will also perform a bucket test just for my own sanity. If the pool chemistry starts going out of whack during the 48 hour no pump run then I will manually mix it around myself (yay!).
Well, just as I expected barely a hint of chlorine left after not running the pump for 2 days. . Just added a hold jug of it per pool math so we'll see how it goes. Water still looks good though.
Yeah, I know it was the sun. I'm just happy the water didn't change colors on me but I guess that doesn't happen easily when your pool is maintained the TFP way.
My ph is out of control as I can't seem to get it stable. Is it because I have a spillover that runs 10 hours a day? My chlorine is also getting murdered everyday (adding almost a gallon a day because it always drop to 0 after 18 hours). I assume that's because we use it everyday and the pool sees sun the whole time its out.
Here is where I'm at now
FC - 5.5
TC- 6
PH - >8.2
TA - 110
CYA - 40
Yes, stop running that, or run it an hour or less per day. Also, your TA is high-ish. Getting that down to 60-80 range will help slow pH rise. Adding acid to lower ph will slowly lower TA. Or you can do it faster here, Pool School - Lower Total Alkalinity
Raise CYA to 60 to help with FC loss to the sun.
