PH high after rain

[Envieddesigns]

Good day to all,

I know after rain the PH is expected to take a swing -/+. Mine went up to 8.2 from 7.8 since yesterday after some rains.
My question, do I dose to lower my PH keeping in mind that
1. I have to top off my pools water level and
2. More rain expected throughout the day today.
Should I just top off wait for the rains and recheck levels tonight or tomorrow?

today’s results
FC 4.5
CC 0.5
PH 8.2
TA 140
CSI 0.91
CYA 40 (tested yesterday)
Temp 85

I would add some acid today as your CH must be fairly high if you are getting a CSI of nearly 1. Scaling is possible.

EDIT - checked your Poolmath Logs. CH 0f 350 is fine. Your higher TA and elevated water temperature are pushing the CSI higher.

drop your PH and let the rain fill your pool for free
