Complete nutrient for denitrifying bacteria Features: The use of NUTROBACT is particularly recommended, in combination with BACTERYA and/or BIO-NITRONEX, in freshwater and marine aquariums that are deficient in bioavailable carbon (carbon is essential for the metabolism of bacteria involved in the transformation of nitrates and phosphates). Its formulation improves macronutrient balance and increases BOD (biochemical oxygen demand), promoting the denitrification process through the proliferation of bacterial cells. Its use ensures the supply of B vitamins, a factor limiting bacterial growth, promoting optimal bacterial growth and consequently improved water quality. ADVANTAGES Provides a high supply of carbon that is immediately assimilated by bacteria; Counteracts the decrease in bacterial biomass; Optimizes the Redox potential by influencing BOD; Promotes the biological transformation of nitrates and phosphates; Facilitates the water clarification process. Effective and easy to use thanks to the disposable vials; non-flammable, non-toxic, does not emit harmful vapors. COMPOSITION: Concentrated carbon in an aqueous solution. DOSAGE: One 5ml vial for up to 500 liters of water, once every 7-15 days, as needed. USE: Shake the vial before use, extract the liquid with the appropriate pipette. Pour the required amount directly into the aquarium. Avoid overdose: although this has no toxic effects, it could cause excessive bacterial proliferation, causing a decrease in dissolved oxygen in the aquarium. STORAGE: It is recommended to keep the product at low temperatures, preferably in the refrigerator.
