ZooBlast Wide range zooplankton complex for live corals & reef aquaria Features a nutritious complex of several naturally occuring zooplankton in a wide range of sizes from 200 to 2,000 uM. ZooBlast is not made from ground up shrimp or fish like several other products are, but is made with actual plankton! ZooBlast provides for growth and increased coloration, by providing proteins, naturally occuring lipids, including important omega fatty acids EPA and DHA, and a wide range of vitamins. It also contains carotenoids, for coloration. ZooBlast does not require refrigeration, but refrigeration will prolong shelf life. Use in aquarium keeping ZooBlast is useful for feeding hard and soft corals, sponges, filter feeding worms, tunicates and clams of all types. It is particularly suited for those that feed on mesoplankton. Many species of marine fishes will also feed on ZooBlast. It is recommended that you turn off your protein skimmer and other filtration for 15 to 30 minutes prior to adding the ZooBlast to the aquarium. Be careful when feeding liquid foods, not to overload the system. It is recommended that you not add more than the recommended dosage of any food per day. 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, Ocean Snow, MicroBlast and PhytoBlast. 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 mesentarial filaments, using their nematocysts to capture prey, and entrapping prey on their sticky tentacles with mucus and drawing it into their mouths. Directions Shake well prior to use. Add 1 capful (5 ml) per 50 US-gallons (200 L) of marine aquarium water 2 to 3 times per week, in a area of high flow. Expert use Target feeding is the best method of addition. Use a turkey baster, pipette, or similar tool to release upstream of animals to be fed. Do not touch corals with tool. Do not insert tool into this bottle, particularly do not allow aquarium water to enter the bottle, to do so will introduce bacteria into the product and accelerate its decomposition. Instead, pour appropriate amount of ZooBlast into a cup and use the tool in the cup. Feed all that you pour and do not return any product to the container (again to prevent contamination).
