Vitamin Shoppe sales it. Price around 8 dollars, why do you use it?
I was thinking about using it under my MGOCPM the next time I dirt a tank as a slow release source of calcium and magnesium. Also to help neutralize the acidity of the soil.

Would item 150517044161 on ebay do it ?
Nah. Dolomite lime can contain some stuff other than calcium and magnesium which can range from metals to oxides. Plus it's in a powdered form making it water soluble. I'm looking for the gravel-sized stuff.
