DrTim's Aquatics Ammonium Chloride 2oz

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, reviewing, and following our recipe for successful fishless cycling.

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
