CSI

[Sitz]

Hello everyone,
Just a quick question about csi. My current levels are
FC 6.5
CC 0
PH 7.4
TA 70
CA 90
CYA 70
CSI via pool math -0.93

My pool is vinyl with SWG so my understanding is that calcium isn’t needed. Should I raise my ph to 7.6 or 7.8 or raise the calcium to a level closer to 200 in order to get that csi down. I don’t want to damage my equipment. Thanks for any input

With a vinyl pool and no heater in your signature, there is no need to add calcium. A negative CSI proves that there should be little worry about scale developing on the cell plates. All your numbers are within range. I wouldn't try to adjust anything at the moment. You're doing great.

Turn off Tracking CSI in the app settings. No need for you to bother with it.

Thanks for the quick responses. To clarify I do indeed have a heater. It was in my signature before but I will re add it.
Still no need to worry about csi ?

What heater?

It’s a Hayward 250,000 btu

Look at the owners manual. Many gas heaters recommend a CH of 200 ppm based on steam boilers of the past. Your gas heater is no steam boiler, but up to you if you wish to add calcium.
