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 consumption is much lower.
Calcium reactors have evolved into several types that require different media sizes. We now offer the original ARM™ fine for downflow, slow upflow, and fluidized bed type calcium reactors and our ARM™ coarse for rapid upflow type reactors. No matter the reactor, CaribSea has you covered.
