Awesome! This product has been added to your cart

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 (10-15 mm) allows for maximum carbon dioxide penetration, and the exclusion of gastropod shells insures 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.

  Does exactly as it says on the tin (or tub :) )... perfect for medium to large reactors and I've found I don't need to dose additional strontium .

  A good mix of course coral bit which is great to use in a calcium reactor- a good price for what you get- I was expecting a lot less.
