In most aquariums, the biological cycle is started by introducing fish into the aquarium. The fish excrete ammonia, which acts as a food source for nitrifying bacteria. Nitrifying bacteria convert ammonia into nitrite and then nitrite into nitrate. Fritz Ammonium Chloride (NH4Cl) can be used as a source of ammonia to initiate the growth of nitrifying bacteria without the presence of animal life. Fish should not be present while using ammonium chloride.

Directions & Dosage

Use 4.5 g (approximately 1 level tsp) per 100 U.S. gallons (380 L). This dose will create an ammonia concentration of approximately 4 ppm. 

  • Use along with nitrifying bacteria (FritzZyme or TurboStart) as a food source
  • No equipment restrictions necessary
  • Contraindications: DO NOT add Ammonium Chloride to an aquarium with livestock present
  • Dry products measured by volume (teaspoons, cups, etc) will always give approximate results - use a gram scale if available. If a gram scale is not available, be sure to test for correct concentration after use.
  • Overdosed? Perform small water changes if needed to dilute
  • Test with an ammonia test kit with a range up to at least 4 ppm

NOTE: Be careful not to use too much ammonium chloride. Raising ammonia levels above 5.0ppm may actually slow the cycle time.

Safety Data: Keep out of reach of children!
