Low CH with and high pH, trying to manage my CSI #

[LAFelipe]

We just had a RO treatment at the beginning of winter and I am trying to keep my CH as low as possible because I know as soon as summer it's going to be going up on it's own. The way things sit right now my CSI numbers are between -.3 to 3 at a pH range of 7.8 to 8.4. Is it OK to have the pH higher than recommended as long as I manage the CSI value? My current values are as follows:

FC 3.5
pH 7.8
TA 80
CH 275
CYA 40 (just pumped out a ton of water because of rain and I'm waiting for my pH to go up before adding more stabilizer)
Salt 2800
Temp 60
CSI -.21

Yes. All your values look Just fine, except FC. Well, it is OK, but just. You might want to keep it 4-6 to avoid algae. Have you read this? Link-->FC/CYA Levels

We've had so much rain lately that all my values have gone down. I just added liquid chlorine this morning to get it up.

Just to reiterate, I can ignore Pool Math's warning for pH outside range as long as CSI is OK? Thank you very much.

Yes, with a caveat. Don't let it go below 7. Generally, keep it in the 7s. 7.8, 8.0, even 8.2 is ok.

Awesome, thank you!
