Our Mixed Reef Food delivers a palatable and highly digestible balanced feed. It is a complete pet food for corals. Research suggests that feeding may improve the photosynthesis rate by increasing zooxanthellae numbers within the coral. These convert the energy from sunlight into the chemical energy required for growth. Our micronised flake is milled to emulate the suspended particulate matter found naturally in seawater which corals trap in their tentacles. Micronised Flake Pot Sizes : 50g, 500g Formulated for all small polyp stony corals, soft corals and other filter feeding species.
