Recommended pH Level For Pool Closing

[ghall6292]

I didn't make any notes from last year except for chlorine levels and Polyquat levels for closing my AGP. Am I correct to think that pH will rise gradually by Spring? I normally run it at 7.5/7.7 when open. Should I leave it alone or lower it to close? If so, what's the recommendation? Thanks!

On a good note, water temp hit 60 this morning. Should have closing completed in the next week.

Thanks, Marty. I have a laminated version of that to take out with me during my close so I don't forget anything. Mine is a bit "customized" so that anyone could close my pool if I was unable to do so. Also have the same for opening. However, it only speaks to chlorine and polyquat; says nothing about pH.

Regardless, pH will settle in relation to the carbonate alkalinity of your TA. Not something to be concerned with on a vinyl pool unless the CH is well above 400 ppm.

Thanks again! Sounds good. My TA is 80-ish and that's why my pH runs where it does: because it wants to... . My CH has been 125 almost forever, so I guess I'm good to go.
