A specially formulated micronised flake from Vitalis designed for specialised feeding of corals. It has been indicated by research that feeding may promote the rate of photosynthesis by increasing the level of zooxanthellae, which convert the energy from sunlight in to the chemical energy needed for growth, in the coral. The micornised flake has been milled to replicate particulate matter in the water column as is naturally found in seawater.
