Formulated specifically for marine aquaria.• Used in conjunction with MicrōBacter7, establishes and develops biological filtration by providing critical nutrients in specific forms and ratios.• Ethical and effective; encourages microbial proliferation without the use of poor nutrient sources, such as fish food (rich in refractory organic compounds) and so-called “starter fish”.• Indirectly benefits corals and other suspension-feeding invertebrates by encouraging reproduction of bacterioplankton (an important food source for those organisms).• Helps prevent bleaching in zooxanthellate corals.• Encourages polyp-expansion in corals, anemones, and their allies.• Formulated by a marine scientist.
