I’m having some major calcium issue. It stays consistent 590s. It’ll drop a little, about 8 per day to 560s. Then water change will bring it back to 590-600.

About 2-3 month ago my ca reading was wrong and dosed. But stopped once I realized reading was wrong.

Could old Ca could be mixing whole water change?

62gal

KH 10.2
Mg 1365
NO4 10.9
PO4 .1
pH 8.3
Temp 78-79
Salinity 35/1.025

No issues with corals or inverts so far

Are you using rodi water?
what salt are you using?

I don’t know if the values are accurate, and as mentioned above, the values are not a concern, but obviously the salt mix is the source.
Could be excessive salinity, a bad calcium test, or a bad source of new salt water.

My rodi system is set up for human consumption so it has a remineralizing stage. It threw off my hannah checkers when I cleaned my vials with that water.
Oh?!! Then what water should I use to clean the vials? Salt water?
