How do you figure that. Its easily raised with a magnesium additive from one of the name brands or like many of us, the magnesium that was mentioned here.

Niloc, when I ran my co2 reactor, my magnesium always seemed to stay around 1350ppm when using Carib-sea media. I tried the Geo-Marine crushed coral, which is a lot cheaper but never measured or used it long enough to see how the magnesium was from it.
