Additional Information

• 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 (2-3mm) 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.


• The fine grading of the original ARM media is designed to be used in downflow, slow upflow and fluidized bed type calcium reactors.
