    Overview

    • High-purity, magnesium-rich mineral that may be employed in traditional calcium reactors, or even blended in to pre-existing aquarium substratum, to gradually increase and maintain the magnesium concentration in the system.
    • Provides magnesium, which helps regulate the balance between calcium and carbonates in aquarium water, and is a component of aragonite, the mineral secreted by reef-building organisms to form skeletal material.
    • Composed of magnesium, calcium, and carbonates.
    • Optimal average particle size for use in media reactors and calcium reactors.
    • Free of chloride and sulfate.
    • Mined in the United States.

    Overview

    • High-purity natural mineral that may be employed in traditional calcium reactors, or even
      blended in to pre-existing aquarium substratum, to gradually increase and maintain the
      calcium concentration and alkalinity in marine aquaria.
    • Strong source of calcium, the most abundant cation by percent mass in aragonite, the
      mineral secreted by reef-building organisms to form skeletal material.
    • Through dissolution, provides calcium, magnesium, strontium, potassium, and carbonates.
    • Aids in increasing alkalinity to stabilize pH and encourage rapid biogenic aragonite
      formation.
    • Optimal average particle size for use in media reactors and calcium reactors.
    • Free of chloride and sulfate.

    ReBorn coarse aragonite media for use in calcium reactors

    ReBorn is composed of fossil skeletons of reef building corals sustainably harvested from pristine sites in the Western Pacific Ocean. When used in a calcium reactor where it is dissolved with CO2 ReBorn not only replenishes calcium and carbonate alkalinity, it also replenishes strontium and trace elementsin the same proportions they are used by corals to build their skeletons.

    Unlike many other calcium reactor media, the coarse size of ReBorn allows for unrestricted water flow and easy diffusion of carbon dioxide, for maximum efficiency and easy maintenance of the calcium reactor. The naturally porous structure promotes carbon dioxide penetration assuring a uniform dissolution rate. ReBorn dissolves completely and will not turn to mush! These features combinedwith its very low phosphate and silicate content mean that ReBorn is the ideal media to use for promoting the growth of live corals, clams, calcareous algae, and other calcifying creatures in a reef aquarium. ReBorn is rinsed in RO water prior to packaging, so no rinsing is necessary before putting the media in a calcium reactor.
