## Overview

Fritz Pro Aquatics Ammonium Chloride is a highly concentrated, professional-grade ammonia source designed for fishless cycling. It enables the safe and efficient establishment of nitrifying bacteria in new aquariums, eliminating the need to expose fish to toxic ammonia levels. With precise dosing, trusted purity, and made in the USA, it’s the go-to choice for aquarists aiming for a healthy, balanced aquatic environment before introducing livestock.

## 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.
