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

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!

I purchased the 4oz bottle to dose with thinking 2oz wasn't enough. I used a total of 180 drops. I have almost a full bottle still. Doesn't even look like I used it. It's really good stuff though, get's your tank full of Ammonia in no time. Will always recommend this for starting a tank.
