PH keeps rising

[hilda]

I'm wondering what keeps making my PH rise

Thurs. 4/27
FC 13
CC .5
PH 7.5 added muriatic Acid
PH 7.2 after MA

Fri 4/28
FC 13
PH BACK UP 7.5

Why does my PH keep going up? This are the only ones I'm checking daily
4/23
TA 110
CYA 80 last time I checked this two

Thanks In Advance

Welcome to TFP

How are you chlorinating? A SWG can cause PH to rise.

Lowering your TA will most likely help stabilize the PH.

Keep knocking that Ph down till it, in turn, lowers your TA. That should help
