CaribSea 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 (7,390 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 gastrpod 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. A.R.M. has the highest solubility of any reactor media available (metastable at 8.2), so CO2 consumption is much lower. A.R.M., its what yoru corals are made of.

Calcium reactors have evolved into several types that require different media sizes. We now offer our original ARM™ fine for downflow, slow upflow, and fluidized bed type calcium reactors and our ARM™ coarse for rapid upflow type reactors. No matter the reactor, CaribSea has you covered.

Best by far for magnesium

REVIEW
This stuff is the best by far for magnesium addition via a calcium reactor. The other media's I've tried have always led to me eventually having to monitor and adjust my magnesium, now I am pretty confident using this media it's a non existent problem. Never have any p04 issues and the media melts a...Read More

REVIEW
This media is by far the best I've used; does not turn to mush like others I've used. To be clear I use ONLY the course media not the original.

Calcium media

REVIEW
I love it. I bought the coarse media. There is no way it will be picked-up in my Calcium reactor pump again. When I took my Korralin calcium reactor apart, there was media in my Eheim pump intake from over the past year. This will eliminate that problem from reoccuring. I strongly recommend this med...Read More
