CSI ratio increasing as temperature drops....

[uraceulose]

My water temp has gone from 80ish to about 65ish in the last 2 weeks.

About to turn on the SWCG tomorrow.

The SWG water balance on pool math recommends staying 7.2 - 7.5 which I've been keeping pretty close the last month or so.

In order to keep CSI in check with the colder water...am I okay to run pH more like 7.6 - 7.8 or should I let the CSI run up to -.50 ish and keep PH down below 7.6 ?

Thank you,

Donnie

Can you post a full set of results? FC, CC, pH, TA, CH, CYA, Salt.

Cannot see any results in your pool math logs.

I would not continue to drive pH down.

With a TA of 70, your pH should be fairly stable around 7.8-8.

Let pH rise...when it gets to 8, reduce to 7.8.

Your CSI will be -.18 to -.06 with pH between 7.8 and 8.

Sounds good. Thank you sir

Any ideas why my pool logs won't show on here? I believe I have the setting correct in the app?

Thank you,

Donnie

You need to be logged into Pool Math with the same username/password as TFP.

Ok. I think I got it now
