Reborn - Coral Gravel for Calcium Reactor - 4 kg - 8.8 lb.
Julian Sprung's Marine Aquarium Formula Calcium Reactor Media is sustainably harvested from fossilized coral beds in the Western Pacific. The coarse size allows for unrestricted flow and easy CO2 diffusion, unlike other media types. It dissolves completely and minute phosphate content. Naturally replenishes strontium and other trace elements.
Instructions Add ReBorn to a calcium reactor according to manufacturer recommendations. T This product 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.
