Hmm Calcium is tad high?

I'll recheck them today after I get home. I'd like to know how salinity affects Ca?
Also, I was Kalk dosing for a week but stopped it because I thought it was unecessary on my tank.

higher salinity will indicate a higher concentration of all elements, including Ca.
Since the values are probably correct with the refractometer, and the info about dosing kalk, I think we figured out the high Ca
With a light stock of soft corals, regular water changes are probably enough to maintain calcium, no need for kalk yet.

Ya, it kind of struck me that high alkalinity mixed with high Ca might create precipitation on my tank. I will continue checking my params after water changes. I was battling hair algae for a while which looks like to be under control after every week now.
Once everything is fine, I'm thinking about restocking my tank. Thanks for the answers.
