Fritz Pro Aquatics Ammonium Chloride - Ammonia Source for Fishless Cycling (500 g)

In most aquariums, the biological cycle is started by introducing fish into the aquarium. The fish excrete ammonia which acts as a food source for nitrifying bacteria. Nitrifying bacteria convert ammonia into nitrite and then nitrite into nitrate. Fritz ammonium chloride (nh4cl) can be used as a source of ammonia to initiate the growth of nitrifying bacteria without the presence of animal life. Fish should not be present while using ammonium chloride.

• Essential for Nitrifying Bacteria: Provides a precise ammonia source required for beneficial bacteria such as FritzZyme or TurboStart to thrive and complete the nitrogen cycle when fish are not present
• Only dose in systems with no livestock, for fishless cycling only
• Highly Concentrated Formula: Economical and efficient — just 4.5 g per 100 gallons produces approximately 4 ppm of ammonia. A little goes a long way
• Controlled Start: Fishless cycling can reduce risk to sensitive fish during cycling; always test ammonia levels to confirm the cycle is complete before adding livestock
• Professional-Grade Quality: Trusted by aquarium professionals and public aquariums; dry, stable, and easy to measure for exact dosing
