Liquid ammonium chloride lets you quickly, easily start the nitrogen cycle in your new aquarium. Reagent grade ammonium chloride solution allows "fishless cycling" that effectively establishes beneficial nitrifying bacteria using chemical ammonia as a food source rather than fish food or live fish.
With Dr Tim's Ammonium Chloride Solution, you will rest assured knowing you're adding a safe source of ammonia (with no scents or other dangerous additives). Plus, you can easily track just how much ammonia you're adding to your tank; you simply add 1 drop per gallon of aquarium water.
Simply add Dr Tim's Ammonium Chloride Solution to your aquarium water, take daily measurements of ammonia and nitrite levels with a test kit, and you'll be able to safely add fish to your aquarium in no time! 2 oz treats up to 1,200 gallons.
You can also use Dr Tim's Ammonium Chloride Solution with Dr Tim's Aquatics One and Only Live Nitrifying Bacteria to further cut cycling time.
