• Recommended for advanced reef aquarists for maintaining low nutrient reef aquariums
  • May be used with MicroBacter7, Reef BioFuel, NeoPhos, or Katalyst to improve health and coloration of inhabitants
  • Lowers phosphate concentration without the use of chemical filtration media and pollution
  • Made in the USA


  • Successfully-operated low-nutrient and ultra-low-nutrient reef aquaria rely upon a balance of carbon, nitrogen, and phosphorus in order to enable beneficial microbes to efficiently remove latent organic material by means of consuming it and converting it into additional microbial biomass. The resulting supply of planktonic microbes is exported from the system via protein skimming and/or captured by corals and other suspension-feeding invertebrates, recycling organic material (waste) into additional biomass of these organisms. These nutrients are also required by zooxanthellae for continued existence.



    The ability of microbes to remove nutrients from their surroundings relies upon the presence of adequate supplies of organic carbon, nitrogen, and phosphorus. The aquarist may employ appropriate filtration material to reduce the concentrations of these nutrients, however bringing the nutrient concentrations into "balance" will accomplish the same task. Failure to maintain adequate nutrient content in any reef system may result in bleaching and/or tissue degradation of zooxanthellate invertebrates.

  • Shake product well before using. Do not overdose. Results will be most significant when the system is being

    dosed with MICROBACTER7 on a daily or bi-daily basis.


    1. Using accurate test kits or calibrated digital testing devices, determine phosphate and nitrate concentrations in system. It is assumed that the nitrate concentration in the system is below detectable limits for the testing method being employed.


    2. Apply NEONITRO as directed below to attain a nitrate concentration of ~3 ppm.


    3. Allow 24-hours to elapse; re-test nitrate and phosphate concentrations. If concentrations remain unchanged, then the system is likely carbon-limited. Dose with REEF BIOFUEL at the rate of 1-ml per 25 US-gallons and allow 24-hours to elapse, then re-test phosphate and nitrate concentrations. Continue daily dosing with REEF BIOFUEL until phosphate or nitrate concentrations begin to decrease, indicating that the rate of carbon input to the system matches the rate of phosphorus- or nitrogen-input, respectively.


    4. If phosphate concentration decreases without addition of REEF BIOFUEL or use of KATALYST, nitrate concentration in the system will decrease. Continue dosing with NEONITRO to maintain nitrate concentration of

    ~3 - 5 ppm until phosphate concentration falls to within desired range (suggested 0.01 - 0.02 ppm). Thereafter, dose with NEONITRO as required to maintain desired phosphate and nitrate concentrations.


    Note: If at any time, dosing with NEONITRO results in a prolonged increase of nitrate concentration without gradual decrease as phosphate is taken up, system is likely carbon-limited (remedied by the application of REEF BIOFUEL or KATALYST to the system). Refer to Steps 3 and 4, or to our website (NEOPHOS "Technical" page). 1 ml NEONITRO will increase the nitrate concentration in 1 US-gallon (~3.8 L) by ~5 ppm; 1 drop from plastic bulb pipette (enclosed within bottle) will increase the concentration in the same volume of water by ~0.25 ppm.
