Two Little Fishies Little Reborn

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 C02 Little ReBorn not only replenishes calcium and carbonate alkalinity, it also replenishes 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 these dissolved components.
