Ocean Snow provides an excellent means of supplying both organic and inorganic nutrients to filter feeding invertebrates of all types. It is useful for hard and soft corals, tube worms, clams, sponges, tunicates and others. Continuum recommends that the hobbyist vary the types and sizes of foods delivered into the reef aquarium. Other Continuum foods that make good choices for this food rotation include Coral Exponential, Micro-Blast, Zoo-Blast and Phyto-Blast. Also, occasionally blending the foods and using them as soaks for other foods will give your invertebrates a variety simulating nature. Vary the time of day for feeding, as well, being sure to feed at night for those organisms that primarily feed nocturnally. Many corals feed primarily at night, extending their tentacles and mesenterial filaments, using their nematocysts to capture prey, and entrapping prey on their sticky tentacles with mucus and drawing it into their mouths.
