You are probably doubling Ben's test figure for salt when you should be dividing by 2 to agree with pool store figure.

The ALK could use a boost up to 100 ppm with baking soda. Try a couple of lbs first. The CAL is within the ballpark for a plaster pool. The CYA could come up slightly to between 40 - 60 ppm, or whatever the SWC manual says.

Hope this helps.
