GREAT!!! By David on 5/8/2013David would recommend this product to a friendI used to use Dolomite, but over time while cleaning my reactor out, i would find the media melted and the dolomite just sank to the bottom. I gave Zeo Mag a try, and its much better. It has a clean white color opposed to dolomites dirty color. Also, it dissolves over time and maintains Magnesium. it might be a few dollars more then dolomite but its thousands of times better.
You wont be disappointed.
