domolite
 

Does anybody put domolite into their calcium reactors for Mg ? If so, where did you get it from and what size are the pebbles/grains?

Chin I just started putting in a magnesium granule in my calcium reactor a couple of weeks ago so a little early to see any results yet although I did notice that my mg. has remained at 1300 for the last 2 weeks and I normally have a slight drop in between water changes. I am not sure that it is dolomite but I suspect it is. I got it from Fins Reef and did post a link to it in another thread that I will try and find.
