Helps maintain a balanced nutrient-limited marine aquarium by enabling the hobbyist to enhance the rate of microbial growth and reproduction, increasing the rate of phosphate-reduction and denitrification; this is of particular benefit in heavily-stocked, well-fed.reef aquaria. Replaces "vodka method" of microbial activity- enhancement with a completely safe and.biologically-sound, non-flammable alternative to using vodka or ethanol. Indirectly benefits corals and other suspension- feeding invertebrates by encouraging reproduction.of bacterioplankton (an important food source for suspension-feeding invertebrates). Encourages polyp-expansion in all corals. May be used to help expedite biological filtration in.new set-ups. Formulated by a marine scientist. Liquid. 500-ml.
