Contains elements, vitamins and minerals necessary for healthy shells.
Reef Crystals is vitally enriched with extra measures of calcium, selected trace elements and vitamins. The inclusion of these important substances at concentrations greater than that found in natural sea water assures their extended availability in the reef aquarium, thus optimizing the long-term health and growth of corals, anemones, and other invertebrates.
Fully compatible with all marine aquariums, Reef Crystals also contains a metal detoxifier that neutralizes excess heavy metals, e.g. copper, often found (in elevated concentrations) in domestic water supplies. And the best thing about Reef Crystals is that it's a one-stop solution -- no additional additives required.
