* Coarse calcium reactor media composed of fossilized coral remains
* Coral skeletons sustainably harvested from the Western Pacific Ocean
* Replenishes calcium, carbonate alkalinity, and other elements for coral growth

Unique calcium reactor media composed of fossilized coral remains. ReBorn replenishes calcium, carbonate alkalinity, strontium, and trace elements in the proper proportions live corals need to build their skeletons for growth. Coarse size and naturally porous structure allow unrestricted water flow and easy diffusion of carbon dioxide for uniform dissolution. Sustainably harvested from pristine sites in the Western Pacific Ocean.

Directions: Add ReBorn to a calcium reactor according to manufacturer recommendations. ReBorn is rinsed in RO water prior to packaging so no rinsing is necessary before putting the media in a calcium reactor. Top off the reactor with more ReBorn as needed.

Contents: Aragonite pebbles from fossil corals.

General Information

ReBorn is composed of the fossil skeletal remains 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 elements in the same proportions they are used by corals to build their skeletons. In this way, ReBorn replaces what corals need to grow.

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 combined with 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.
