Got a rainstorm the night I added Muriatic acid to lower my pH and water level in pool went from halfway up skimmer to the next screw on the skimmer plate. Would that amount of rain explain why pH went from 7.4 to 7.9 in 2 days?

I keep forgetting to retest TA, so not sure if it's still 100.

Rain may have contributed if the drops were big and caused spash drops into the pool. TA has a factor too....what is it?

Rain drops hitting the window ac were hitting pretty hard but couldn't see the pool.

Last I measured TA it was 100 but that was prior to MA addition and rain

Today's measurements came in at
PH 8.0
TA 90

It feels like it's going up fairly quick still

Need to go get more Muriatic acid but will do this. Is there a frequency of adding MA too often assuming aeration is raising pH quickly that I should avoid? Ie don't add 3x in one day or as long as the pH is high adding more won't be an issue

Uhm....I can't imagine a need to add that often! ? You'd not be taking the pH down far enough at one time if you had to repeat it the same day.

OK good to know. Thanks for the help. Checked today and the last addition of muriatic acid aerating overnight and wiping last reagant bottle between drops while testing helped. Right at 70 now for TA. Hopefully that will help with the pH rise
