ARM Reactor Media - Coarse, 1 gal. reefugium along with the power wiresContains nearly 50 times the strontium of other brands (7390 ppm). It also contains 381,000 ppm Calcium, 590,000 ppm Carbonate, and 1050 ppm Magnesium. ARM course has the highest solubility of any reactor media available (metastable at 8. 2) so typical CO2 consumption is much lower. Picture for illustration only.
