Brightwell Aquatics Reef Snow effectively replicates the concept of marine snow by combining a “core substrate” of carbonate-bound, non-conservative major, minor, and trace elements (all in aragonite ratios) with marine-derived proteins and fatty acids (all in coral tissue ratios). It does not contain any sugars or their derivatives. Reef Snow delivers both organic and inorganic nutrients to corals and their allies, clams, tube worms, and other suspension-feeding marine invertebrates; it may be of particular benefit to the hobbyist wishing to maintain zooxanthellate soft corals in deep-water biotope aquaria. The collective benefits of providing these nutrients in the same “package” are increased growth rates of both soft tissue and skeletal material. Note: Reef Snow does not require refrigeration, however storage in a cool, shaded area will prolong the shelf-life. Refrigeration will maximize the shelf-life of the product.
