from LittlesilverMax in November 2005 and I have just finished using it up!!!
Bev is gonna be so proud of me cuz I had to continuously supplement to maintain my mg level around the 1350 mark. Like the other Mg supplements (commercial and DIY) they are not very "potent" in terms of Mg concentration. I've heard and read this from many users now. Eg.

Another friend used the Salifert product in a bottle and after dumping in the entire bottle, it raised their mg level by about 75 ppm!!!
I don't know who is crazier - me or this hobby? Its gonna be pricey to maintain mg levels in a high demand sps tank. Imagine 11 lbs of mg into my system in three months

Like another one of my feeble group buy attempts, I tried to get a large shipment out here to cut down/split on the shipping costs.... i think i'm just gonna give up on group buys from herein But I'm going to buy 30-40 lbs in the next month or so in order to have a year long supply of magnesium.
