NOTE: The C-ARM Large is similar to
Schuran and Pacific Coast media. It looks like small finger pieces of coral
skeleton.
ARM™ -
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) 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 typical CO2 consumption is much lower.
