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

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
