Bio kit reef Nano combines 5 Prodibio Nano reef aquarium range products in one box bio digest Nano is made up of nitrifying, nitrate reducing and facultative bacterial strains selected for their ability to convert ammonia into nitrites, nitrites into nitrates and nitrates into nitrogen. Bioptim Nano is a natural product that affects cellular bio activators. It has been specially formulated to accelerate the cellular metabolism of most of the bacteria that live in aquariums. Reef booster Nano is a complete nutrient supplement containing all the elements required by the invertebrates that feed solely or partly on micro plankton and for zooxanthellae carrying coral which need additional microplankton. Iodi+ nano supplies the hard corals in your aquarium with the iodine they need to grow and for coloration. It also helps them to adapt to lighting variations and neutralises the excess oxygen produced by zooxanthellae under excessive lighting and therefore combats coral bleaching. Stronti+ nano provides all the strontium needed for optimum and healthy coral, clam and coralline algae growth.
