Ammonium Chloride Solution for Fishless Cycling

Choose Options
Select Size
This bottle of reagent grade ammonium chloride is for use when fishless cycling. Concentration is 50 mg/L of total ammonia-nitrogen (TAN). Dose 1 drop per gallon of aquarium water.  Use with One and Only Nitrifying Bacteria.

1 drop equals 0.05 ml so this bottle will treat 1,180 gallons.

Generally during a fishless cycle one needs to add ammonium chloride to their tank 3 or 4 times so this bottle is enough ammonia to cycle aquariums up to 250 gallons.

Some conversions:

1 teaspoon equals about 5 ml which is 100 drops
1 tablespoon equals almost 15 ml which is 300 drops

Works well. You can control how much ammonia is in your system, I had to use more than recommended to reach the initial 2ppm (testing about 20 min after adding) but my tank was cycled in 2 weeks.

What a Wonderful way to start a Reef aquarium. Along with Dr. Tim's one and Only my 120 Gallon Reef Tank cycled in 8 Days. 0.0 Ammonia, Nitrite, and 7.0 Nitrate. Now I can get this Baby up and running. Thanks Dr. Tim!!

I just finished fish-less cycling my tank in two weeks using Dr. Tim's Ammonium Chloride and One and Only. Thank you

I have just cycled two tanks using a 3 ppm ammonia concentration associated with Dr Tim's One and Only, by following the instructions in Dr Tim's website. Just like another another reviewer, I found the recommended dosage was off. I used 6ml in a nominal 36 gallon tank, and 1.5ml in a 10 gallon tank to get the 3 ppm. Using the clear ammonia chloride solution is way better than trying to find a household cleaning ammonia solution without additives that interfere with the cycling.
