A.R.M. Calcium Reactor Media, 8 lbs. A complete reactor media containing not only calcium and carbonate, but essential trace elements as well. In fact A.R.M. has nearly 50 times the strontium of other brands (7390 ppm). A.R.M. is processed for immediate use, no rinsing required, and has double the surface area of regular aragonite. Precision grading (2-3 mm) allows for maximum carbon dioxide penetration, and the exclusion of gastropod shells insures the lowest phosphate (less than 1/10 of 1 ppm) and silica (about 1/2 that of other brands) content. This grading also carries in the highest concentration of Halimeda incrassata, an aragonite so pure it has been used as a laboratory standard. A.R.M. has the highest solubility of any reactor media available (metastable at 8.2) so CO2 consu

Aqua Medic Hydro Carbonate 1 liter. Coarse grain. Is a pure and natural product. It is used in calcium reactors, in filters to increase the hardness of water, and as a filter medium or substrate material in marine or Malawi - Tanganyika aquaria. A natural calcium carbonic acid equilibrium is created in all aquariums with an alkaline pH value and in a calcium reactor supplied with CO2, the Hydro Carbonate is completely dissolved to calcium bicarbonate, becoming available for assimilation by hard and many soft corals, sponges, echinoderms, etc.
