We just had our pool installed about 2 months ago. We opted for a little darker plaster than white. We started noticing white spots on the plaster and called to PB to come and take a look. Plaster guy came out and said we had too much calcium in the water (w/o testing the water). No fault of plaster installation. So I took the water to Leslie’s to have the water tested and they said calcium was way too low. We now have our levels corrected but our pool still looks like this? Any suggestions? Truth in this being due to calcium or an error in installation?
