Dr.Tim's Ammonium Chloride is made up of reagent grade materials and is perfect for fishless cycles in reef aquariums. 

  • Odorless
  • Pure Ammonium Chloride
  • No Unnecessary Additives
  • Works Great With Dr.Tim's One & Only


Ammonium Chloride can be used to simulate organic matter that would naturally break down into ammonia. By adding the reagent grade ammonium chloride solution to your tank instead of older methods like using a cheap fish, or tossing in nutrient-rich fish food, you do not have any of the byproducts that decaying fish food and fish waste will produce. Dr.Tim's formula is different from the traditional ammonium chloride solutions you would find at your local grocery or hardware store. Most ammonia solutions will contain unwanted additives to help with scent, and coloration, Dr.Tim's additive uses pure ammonia.

Using the ammonium chloride solution, in conjunction with simple ammonia and nitrite test kits, you have complete control of your tanks cycling process without adding any extra nutrients or sky-high ammonia concentrations.


Instructions - Add the appropriate amount of DrTim's One & Only Live Nitrifying Bacteria to your aquarium. Then add 4 drops of Dr.Tim's Ammonium Chloride solution per gallon of aquarium water to achieve an ammonia concentration of 2 mg/L-N (2ppm) of ammonia. 

It is important to have your UV sterilizer or ozone generator turned off for the initial cycle.

Do not overdose. Do not exceed ammonia concentrations higher than 5 mg/L (5ppm).

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 to use 1 drop use 1 drop, if the bottle says to use 4 drops use 4 drops


Ingredients - Reagent grade ammonium chloride, purified water


Shelf Live - Stored in a cool dry place, the shelf life is indefinite.
