Sounds good, see you then.

Will your friend also be supplying Magnesium any chance?

I will for sure contact in the future when I run out of my calcium though!

Mag is different. It is actually 2 parts - Magnesium Chloride and Magnesium Sulfate. Mag Sulfate is really cheap and not a problem. Mag Chloride, on the other hand, is quiet expensive, and his cost is much more then BRS, so not worth bringing in.
I only have a small amount of each right now. If there is enough of a demand I could bring in a couple bags of Mag Sulphate and order the Mag Chloride from BRS.
