I'm always off on the Calcite Saturation Index and I don't know if I should be concerned. Here are my numbers:
CH 350 (our pool is 9 months old. we started at 290 and it has crept up slowly)
When I put all of my numbers in pool match my Calcite Saturation Index, I get 0.21 and it says "Greater than 0.6 is suggestive of problems for all pools."
All of my numbers are within accepted leveles, although I know 350 is on on high end. The area we live in has high calcium levels in the water.
Is there something I should do?
