A.R.M. Media 8lbs

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.

A.R.M. has the highest solubility of any reactor media available (metastable at 8.2) so CO2 consumption is much lower.

The coarse grading of this A.R.M. media is designed to be used in rapid upflow type calcium reactors. _____________________________________________________________________________________
