Caribsea A.R.M. Coarse Calcium Reactor Media - 8-10 lb
The only aragonite reactor media.
A complete reactor media containing not only calcium and carbonate, but essential trace elements as well.
Contains nearly 50 times the strontium of other brands!
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 and silica levels (approximately half of other brands). This grading also carries the highest concentration of Halimeda incrassata, and aragonite so pure it has been used as a laboratory standard.
A.R.M. is has the highest solubility of any reactor media available, so CO2 consumption is much lower.
Ideal for rapid up flow type reactors.
