Calcium in a SWG- Vinyl pool

[Frunobulax-]

Do I need to worry about CSI with a vinyl liner and SWG? My water has almost no calcium, (30ppm), which gives me a csi of -1.45 according to poolmath.
I actually never checked the csi because it's vinyl, but I was looking at the recommended levels for the swg, and saw there was a value for it.
Thanks.

Do I need to worry about CSI with a vinyl liner and SWG?

No. More than anything a low pH (below 7.2) would be an issue, so keep the pH in the 7.2-7.8 range. However TFP does recommend a minimum CH of 50 for vinyl SWG owners, so you might bring it up just a tiny bit.

Your gas heater needs 200 ppm of calcium for best life.
