Reef Enhance is an all-natural microplankton supplement that feeds corals, corallimorphs, filter feeders, and the copepods and other crustaceans living in a reef tank. The microbes are encysted when dried, so they store as stable dry cysts (up to 2 years refrigerated) rather than a less-stable live culture in water. What it's for Stimulates feeding and reproduction in copepods and other nocturnal reef organisms Feeds hard and soft corals, filter feeders, and grazers - Goniopora, Acropora, Tridacna clams, scallops, sponges, feather dusters, gorgonians, and more All-natural, no preservatives Dosing Standard tanks: 1 scoop per 25 gallons, 3 times a week or as needed Small tanks (10-15 gal): half a scoop Large systems: 1 teaspoon per 100 gallons For best results, mix the dose with a few ounces of aquarium water in a separate container, let it sit 20-30 minutes (stirring occasionally) to improve hatch rate, then pour it into a high-flow area for even distribution. Store refrigerated for best potency. Shipped fast with expert support. Get your Reef Brite supplies from real reefers at Marine Concept Supply, with local pickup at our Wheeling, IL showroom.
