Precision grading (2-3mm) allows for maximum carbon dioxide penetration, and the exclusion of gastropod shells ensures 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. ARM has the highest solubility of any reactor media available (metastable at 8.2), so CO2 consumption is much lower. ARM is essentially what your corals are made of.

Note: All ARM media is packaged by volume in a 1-gallon container. Weights may vary from container to container, but on average one gallon will yield 8 - 10 pounds of media.
