Nutramar Live Phytoplankton offers among the most nutrient-dense live food. CRIT is a blend of the most popular phytoplankton and is specifically formulated to provide vitamins, proteins and omega-3s in a wide variety of cell sizes, along with other phytonutrients vital to a healthy ecosystem. Each pouch contains Chaetoceros, Rhodmonas, Isochrysis, and Tetraselmis. This blend is ideal for a wide range of filter feeders including target feeding clams, sponges or coral. 

Dosage: 
The recommended dose is 15-30ml per 50 gallons, once a day. Turn off protein skimmers for 30-45 minutes while feeding. For target feeding, or to maximize feeding opportunities for corals and invertebrates, turn off circulation pumps while dosing. More densely stocked tanks may benefit from more frequent feedings.
