I just mixed up my first batch of Magnessium last night and it seems to work pretty well. I really can't believe how much money i am saving buy making my own rather than buying tech-m or similar products all the time. I also think its pretty cool being able to run carbon and GFO in my reactor. I don't think i will be needing to order or buy reef suppliments for a very long time, which is cool with me. Anyway, just seeing if everyone was as happy with their stuff as i am.
