Nitrate Minus NYOS Nitrate Minus is ideal for smaller systems or first-time users managing nutrient levels. It gently lowers nitrate to improve coral health and maintain clean, balanced water parameters. Promote the Fast Growth of Beneficial Nitrate-Reducing Bacteria Nyos® NITRATE MINUS promotes the growth of nitrate reducing bacteria. This allows nitrate to be reduced biologically to the detection limit. Phosphate is also reduced to a small extent by skimming off bacterial films. Biological reduction of nitrate (and a small amount of phosphate) Dual formula with short- and long-term components Can be used permanently or temporarily Does not contain toxic methanol Instructions Standard dosage: 10ml/1,000 liters (10ml / 250 gal) daily. If nitrate is below target value: Dose 5ml/1,000 liters (5ml / 250 gal) daily or stop treatment If nitrate is far above target value or is falling too slowly: double the dose to 20ml/1,000 liters (20ml / 250 gal) daily We recommend a nitrate value of 5-15mg/l (ppm) If possible, dose daily using a dosing pump Monitor the nitrate level weekly with the Nyos® NITRATE Test Kit and adjust the dosage as described above if necessary Notes We recommend a nitrate value of 5-15mg/l (ppm) If possible, dose daily using a dosing pump Monitor the nitrate level weekly with the Nyos® NITRATE Test Kit and adjust the dosage as described above if necessary
