HIGH CALCIUM and Magnesium. PLEASE HELP

[Reefadiction]

My 180gal tank crashed 7 months ago and been recovering since. In the past 5months all vital para are good. But 3 weeks ago Calcium and Magnesium slowly climbed.Calcium from 1300 to over 1500 and Magnesium from 1350 to just under 1500. Only running skimmer and reactor is disconnected.
Current parameters:
Ph 8.0
Nitrate 1 to 2
Phosphate under 0.03
Alk 8
Calcium over 1500
Magnesium 1490
Salinity 1.024
Temp 80f
Can high Cal and Mag bring ill affects to sps or even soft corals? If so how can i bring it down with out water changes. I did 25percents water change and it brought the Cal and Mag down by roughly 5percents. But this large water change give my fish ick. Any advices is greatly appreciated. Thanks guys

recent posts have mentiond high MAG levels in efforts to battle bryopsis,,,
People have mentioend levels 2000+,,

dont think high Cal levels will hurt anything other than your pumps


as long as the climb is gradual I think you are safe...

Yeah they climb slowly. I only have a few corals mostly sps and chalice now. And 5 fish. Croals are happly so far with great colors. Thanks for the input. It eases my concern abit. I just dont want another nuke happens to my tank again. Still hurt from last 1. Any chance you can post alink to that recent post in regard to Mag? Thank You very much.
Happy reefing...

Calcium is at what? Are you sure that's correct? What kind of test kits are you using? I would suggest to get a third party to test your water like the local fish store.

I used 2 different test kits. Salifert and Api. They both shows same result. Calcium at 1500 and above. I also notice calcification on my glass in the past couple of weeks. Sure i will bring a sample ti a LFS tomorrow

I have never seen CAL at 1500 and didn't even know that was possible while your other parameters are in check.

Did you test all parameters for the new water mix? How are your corals, do they look stress? If you disconnected your cal reactor and CAL readings are climbing then something is off.

BTW - my corals when stress they don't consume any ALK or CAL for 4-6 weeks.

I agree with Rich. How could your Ca be that high?

How did you test it? My Salifert kit only reads up to 500. Did you refill the syringe a couple times to get the 1300 to 1500 reading?

Correct me if I'm wrong, but I believe a Ca reading anywhere over 500 will cause precipitation, and buildup on warm/electrically charged hardware. You'd have caked calcium all over your pumps/heaters and probably everything else it wants to attach to!!

These values are strangely high. Are you dosing any kind of additives to the tank (may be increasing your big 3).
