ESV`s Spray-Dried Marine Phytoplankton (SDMP) is the most versatile food available to the reef aquarist. SDMP effectively eliminates the need for purchasing or culturing live phytoplankton cultures for your reef aquarium. Phytoplankton is an important first step in initiating a food chain within your closed ecosystem which more closely simulates a natural coral reef food chain. Daily addition of SDMP will not only directly feed the larger inhabitants of your reef aquarium, but also promote the production of zooplankton which in turn can also be a valuable food source for your reef inhabitants. Depending on the feeding method employed, SDMP functions as a filter-feeder food for corals and other invertebrates, fish food, larval fish and invertebrate food, and an enrichment food for Artemia and rotifer culture. The abundance of Highly Unsaturated Fatty Acids found in this strain of marine microalgae causes the foam in protein skimmers to collapse for a few hours allowing the algae cells longer residence time in your aquarium before being exported by skimming. We provide a measuring spoon with each container. Each level spoon of SDMP contains approximately 60 milligrams which is equivalent to 150,000,000 algae cells! Although the very high levels of Highly Unsaturated Fatty Acids (especially Docosahexaenoic Acid shown to be critical for proper marine larval development) makes SDMP unique, it also functions as a source for the following trace elements, vitamins, amino acids, and minerals: Cobalt, Copper, Iodide, Iron, Manganese, Molybdenum, Nickel, Selenium, Silicon, Tin, Vanadium, Zinc, Vitamins A/E/B12/C, Thiamin, Riboflavin, Pyridoxine, Pantothenic Acid, Biotin, Folic Acid, Choline, Niacin, Aspartic Acid, Threonine, Serine, Glutamic Acid, Proline, Glycine, Alanine, Cystine, Valine, Methionine, Isoleucine, Leucine, Tyrosine, Phenylalanine, Lysine-HCL, Histidine-HCL, Arginine-HCL, Tryptophan, Calcium, Potassium, Phosphorus, Sodium, Magnesium, Sulfur, and Chloride.
SUGGESTED USES: DIRECT FEED FOR FISH, CORALS, AND OTHER INVERTEBRATES: We suggest 1 level measuring spoon (supplied) per 20 gallons of aquarium water per day. Tap the spoon on the top edge of the aquarium and allow the spoon-shaped clump of SDMP to drop onto the surface of the aquarium water. Many fish will attempt to consume these clumps and in doing so will not only be receiving some highly nutritious food, but will also help disperse the SDMP throughout the system. Circulation pumps will further disperse the food. When used in this manner, the average particle size of the product ends up between 10-80 microns. For a smaller particle size (10 microns and less) premix the SDMP in a blender for 1 minute. Fine mechanical filtration should be removed while feeding SDMP.
FISH AND INVERTEBRATE LARVAL CULTURE: We suggest 1 level measuring spoon per 4 gallons of culture water twice per day. Predisperse the SDMP with water for one minute in a blender before use. Aerate culture water sufficiently to prevent low dissolved oxygen levels. Change water frequently to prevent nutrient accumulation.
ARTEMIA ENRICHMENT: After predispersing with water in a blender for one minute, add to Artemia culture at a ratio of 1 level measuring spoon SDMP per 30,000 Artemia nauplii and aerate heavily for 12 hours before using Artemia.
ROTIFER ENRICHMENT: After predispersing with water in a blender for one minute, add to rotifer culture at a ratio of one level measuring spoon SDMP per 200,000 rotifers and aerate heavily for 12 hours before using rotifers. STORAGE: Keep tightly covered and refrigerated when not in use. Keep free from moisture. Never add wet measuring spoon to container.
