Ammonium Chloride

Ammonium Chloride Solution for Fishless Cycling

Use with One & Only Nitrifying Bacteria

This bottle of reagent grade ammonium chloride is for use when fishless cycling. Concentration is 40 mg/ml of total ammonia-nitrogen (TAN). Dose 4 drops per gallon of aquarium water.* Use with One and Only Nitrifying Bacteria.

Generally during a fishless cycle you need to add ammonium chloride to your tank 3 times so:

  • a 2 ounce (60 ml) bottle will cycle 100 gallons (359 liters)
  • a 4 ounce (120 ml) bottle will cycle 200 gallons (757 liters)
  • a 8 ounce (480 ml) bottle will cycle 400 gallons (1,514 liters)

We strongly recommend downloading and following our recipe for successful fishless cycling:

  • 100 drops = 5 ml = 1 teaspoon
  • 300 drops = 15 ml = 1 tablespoon
