Calcium problems.

[reefburnaby]

Hi,

If you are using ARM, which happens to be near 100% Aragonite, then you will get about...oh... < 5% magnesium. I would email Caribsea and see if they add magnesium in to their mix because Aragonite, as a rock, doesn't have much magnesium. Remember that Domolite discussion...Aragonite is better because it can't over dose Magnesium !

So, how long have you had this low calcium state ?

IMHO, I would try the magnesium theory on a small bucket of tank water before trying it in the system.
