Current levels, Cal and Mag too high? What to do?

Salinity 1.024
Phos 0.5
Alk 3.25/11.375
Nitrate 0
Calcium 520 possibly higher
Magnesium above 1500

Currently Dosing C-balance but have stopped the calcium part and am still dosing the alkalinity part. Should I just not dose anything or can I dose only the Alk part of C-balance and both the magnesium and calcium will come down on their own or will their be some kind of imbalance? Then maybe after a few days check the levels again and adjust dosing of the C-balance to prevent it from going so high again? I am also going to do a 10% water change this evening.

 

I would leave it... Mg and calcium high but I would not be overly alarmed by it. I would think after doing the water change and not dosing a couple days. I would then test and when everything is back to normal I would cut the dosing down a bit,

 

What do you have in your tank?

 

What brand of test kits are you using?

Many times guys run magnesium 1600+ to eradicate, or keep algae like bryopsis from taking over.

The calcium seems a bit high, like not realistic high, based on your alk levels.

 

Mostly softies and a couple lps, all the fish and coral are lively colorful and happy though so i think im not gonna stress it much, jus gonna lay off the supplement for a couple days and adjust dosing afterwards, thanks guys

 

Unless your calcium isn't precipitating you should be fine. Did you test before dosing. Softies and LPS don't use a whole lot of calcium.
