Unique calcium reactor media composed of fossilized coral remains. Little ReBorn replenishes calcium, carbonate alkalinity, strontium, and trace elements in the proper proportions live corals need to build their skeletons for growth. Smaller size and naturally porous structure allow easy diffusion of carbon dioxide for uniform dissolution.
Little ReBorn is composed of sustainably harvested fossil skeletal remains of reef building corals. When used in a calcium reactor where it can be dissolved by CO2 Little 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 Little ReBorn replaces exactly what corals need to grow, and these dissolved fossils are “born again” when the live corals in your aquarium deposit the dissolved components. The size of Little ReBorn also makes it an ideal medium for post-calcium reactor pH adjustment.
