## Overview

Fritz PRO Ammonium Chloride (500g) is a premium-grade, pure ammonium chloride powder designed to initiate the biological nitrogen cycle in aquariums without fish. Manufactured in the USA, it supports safe, fishless cycling by promoting nitrifying bacteria growth, ensuring a healthy aquatic environment before introducing fish. Perfect for hobbyists seeking a reliable, high-quality solution to establish a thriving aquarium ecosystem.

## 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.

## 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.
