Ammonium Chloride Solution

Dr. Tim's Aquatics Ammonium Chloride Solution


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 for every 3 litres of aquarium water.*  Use with One and Only Nitrifying Bacteria.
Size: 2oz


Generally during a fishless cycle you need to add ammonium chloride to your tank 3 times.
Some conversions:
1 drop equals 0.05 ml
1 ml equals 20 drops
1 teaspoon equals about 5 ml which is 100 drops
1 tablespoon equals almost 15 ml which is 300 drops
*NOTE: As of November 1, 2016 we changed the concentration of the ammonium chloride solution so it now takes 4 drops per gallon. The previous version called for 1 drop per gallon. Please see the label on your bottle to determine how much to use. If the bottle says use 1 drop use 1 drop if the bottle says use 4 drops use 4 drops.
