There are slight variations on Calcium Hardness targets, as reported here and here and here
TFP Water Chemistry:
TFP SWCG Guidelines:A plaster pool should have CH levels between 250 and 350 if possible.
From Diamond Brite Install Ref:Adjust Calcium Hardness to 300 ppm for plaster
From Pentair IC40 Manual:Calcium Hardness: 200 PPM
Since my pool is on day 25/26 and am planning on starting to add salt in another 30 days, what should be the ideal CH level? What should it be while the plaster is curing?Calcium Hardness 150 to 400 PPM
