Cooler Days Ahead

[Bcorig]

The weather here in Southern California has cooled off go the point where my Ic40 shut off.
I have been maintaining pH = 7.6 and TA = 70 for the summer - usual water T = 76-78F.
The water T will now be 50-55:
Should the target pH and TA be adjusted for colder water?
I didn’t change anything last year and everything seemed fine.
Thanks

No change. Only thing different will be slower burn off of FC and slower rise of pH due to less fill water being used.

Maintain all parameters as normal.

A minor thing you didn't ask about is that CSI goes down with temperature. So if you were already near the minimum, you might need to boost CH to keep the plaster safe.

Exactly what I’ve observed over the past 2 weeks. Thanks again.

CSI still WNL, thanks.
