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

Lived up to it'a promise. It cyced my tank in 8 days along with Dr. Tim''s Nitrifying Bacteria. The step by step instructions were extremely helpful. Happy to get my little green spotted puffer in his new home!!

I'm starting my first fish tank and after finding Dr. Tim's on YouTube I got this ammonia as well as the freshwater starter kit and it has been wonderful! Easy to use and does just what it says it will. Highly recommend.

I used this in combination with One and Only Nitrifying Bacteria and cycled my 55 gallon in 10 days while charting its progression on a graph. Good stuff! It works!
