Used effectively to Fishless cycle your tank without the use of fish or foods.
pure ammonium chloride (NH4CL) that will add a source of ammonia to begin and complete the nitrification process.
Aquarium ammonia concentration should be raised to 3-4 ppm before adding a source of nitrifying bacteria such as FritzZyme® or FritzZyme® TurboStart.
Be careful not to use too much ammonium chloride. Raising ammonia levels above 5.0ppm may actually slow the cycle time.
One level teaspoon of ammonium chloride is approximately 4.5 grams; 4.5 grams per 100 gallons of aquarium water will create an ammonia concentration of approximately 4 ppm. Continue to monitor both ammonia and nitrite levels. Do not reapply ammonium chloride or add fish until both ammonia and nitrite levels are at or near zero concentration. Once ammonia and nitrite concentrations are at zero, you should either add a second dosage of ammonium chloride or add fish so as not to interrupt the food source of your biological filter for more than 72 hours (3 days).
