I wanted to know anyone out there with information/links about benefits & effects of a dosing regiement of Calcium Chloride and Magnesium Chloride. Detailed information of the chemical breakdown of these compounds in a reef tank, byproducts, etc... I curious because I know the need for mag and calc levels in the tank, and I happened to come across a rock salt mixture that is sodium cloride/calcium cloride/magnesium cloride. Ive read people dosing dow flakes(calc cloride), but I've never read the addition of Magnesium cloride.
