Phosphate and nitrate accumulation are common problems for manh reef aquariums because they slow the growth rates of coral and lead to blooms of red slime and hair algae. In nature, bacterioplankton keep these nutrients in check by metabolizing nitrate and phosphate alongside dissolved organic carbon. In aquariums, dissolved organic carbon is quickly exhausted, causing nitrate and phosphate to accumulate. Thrive's Bio-Stimulant crush provides dissolved organic carbon that is used by bacterioplankton to create new biomass from nitrate and phosphate. This biomass acts as an efficient nutrient sink and is removed from a reef aquarium by the feeding activity of corals and skimming. Bio-crush is made with aragonite and biologically degradable polymers. Must be fluidized in a reactor.
