Our Coral Essentials, Coral Power Bacteria Food is a concentrated solution of Acetic Acids and Sucrose for marine aquariums. It is essential to promote nitrifying bacteria growth in all marine systems which aids in the breakdown of organic waste. Nitrifying bacteria (nitrifiers) consist of two bacteria species. The first strain settles as soon as ammonia is present, the second one settles as soon as nitrites are present. Nitrifiers rely on a biochemical reaction (oxidation). Under low oxygen levels, the bacteria use nitrite / nitrate as an acceptor, or garbage collector, reversing the process from nitrifying to denitrifying i.e. removal of nitrates. As an aquarium is loaded with oxygen, the bacteria need ammonia (i.e. food) to stay alive. Coral Power Bacteria Food provides sufficient components to ensure the proper function of nitrifying bacteria.
