## Overview

Fritz Pro Aquatics Ammonium Chloride is a highly concentrated, professional-grade ammonia source designed for fishless cycling. It enables safe and efficient establishment of nitrifying bacteria in new aquariums by providing a precise ammonia dose without risking fish health. Trusted by experts and made in the USA, this 500g powder ensures controlled, economical, and reliable nitrogen cycling for a thriving aquatic environment.

## Description

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.

## Features

- 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
- Made in the USA, 100% employee-owned company

## Questions & Answers

**Q: Is 1 teaspoon good for a 10 gallon?**
A: 1 teaspoon is way way too much for 10 gallons.  Less than 1/8th of a teaspoon for 10 gallons - I'd suggest 1/16th.

**Q: How much do I use for a 75 gallon tank?**
A: 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. I would start with half a teaspoon. Check the level of ammonia, if you still haven’t reached 4ppm then add smaller doses until you do.

**Q: Typically you try to keep chlorine out of an aquarium (esp. saltwater). My goal is a fishless cycle; is there a reason to use nh4cl over pure nh3?**
A: My thought is that the dechlorinator used in water changes should remove the chlorine put in when using the Ammonium chloride.  It worked for my fishless cycle.

**Q: How much do i put in for a 55 gallon tank?**
A: Depends follow Mr Crafty Pants on YouTube.
