Product details

ReBorn 4.4kg Coarse Aragonite Calcium Reactor Media 8.8lbs Two Little Fishies is calcium reactor media designed for marine aquariums that use a calcium reactor. In these systems, the reactor lowers pH and dissolves aragonite media so it can help maintain calcium and carbonate alkalinity, supporting overall reef chemistry stability. ReBorn is supplied as coarse aragonite media, intended to allow strong water flow and efficient diffusion of carbon dioxide through the reactor bed.

Features:

  • Coarse aragonite grain size supports unrestricted water flow through the calcium reactor chamber.
  • Designed to help carbon dioxide diffuse easily for efficient dissolution of the media.
  • Uses fossil skeleton material from reef-building corals as the aragonite source.
  • When dissolved, ReBorn is intended to replenish calcium and carbonate alkalinity, along with strontium and trace elements.
  • Built for practical use and maintenance—its coarse nature supports steady performance rather than breaking down into a soft, mushy texture.
  • Compatible with calcium reactors that use aragonite media for ongoing supplementation of reef aquarium parameters.
