Reef Endurance Small Calcium Reactor Media, 16kg (CLOSEOUT) – Filtration

Replenishes Calcium, Carbonate Alkalinity, and Essential Trace Elements

Reef Endurance calcium reactor media is natural aragonite rubble from sustainably harvested fossil corals, collected and cleaned for use as the sole media for calcium reactors to support rapid coral growth. Small 3-4mm rubble is the ideal grain size for small calcium reactors and a second media chamber for post-calcium reactor pH buffering. Available in small 3-4mm and large 4-6mm grain sizes.
