Tropic Marin Pro-Coral Reef Snow -a natural source of nutrients for corals and other filter feeding animals. Recently marine scientists have become increasingly aware of reef snows central function as a vital source of nutrients on natural coral reefs. Dissolving Tropic Marin Pro-Coral Reef Snow in RO/DI water forms a thick solution that can be combined with nutrient supplements and foods such as Tropic Marin Lipovit and Pro-Coral Zooton and Pro-Coral Phyton to mimic this natural nutrient source.When added to the reef aquarium, Tropic Marin Pro-Coral Reef Snow together with the food and supplements form highly nutritious flakes similar to those of natural reef snow. By varying the concentration of the Pro-Coral Reef Snow solutions, the size of the flakes can be adjusted to the specific filter feeding animals maintained in the aquarium. The portion of Pro-Coral Reef Snow and the nutrients it contains which falls to the aquarium floor is only slowly decomposed by bacteria, thus further
