Reef Central Online Community - View Single Post - Why are my Ca levels stuck at around 400?

I already added 6.2 ounces (175g) to my 420g (1600 liter) system.
That raised the calcium levels from 340 to 365.

I agree that Mg level should be higher.
There have been Magnesium rocks in the Ca reactor for 2 months now.
It seems like I need to add more of them.

I also have some Magnesium Sulfate lying around, but I don't like it much since a lot is needed to raise Mg levels.
