## Overview

Fritz PRO Ammonium Chloride (500g) is a pure, high-quality chemical designed to initiate the nitrogen cycle in aquariums without fish. By providing a safe ammonia source, it promotes the growth of beneficial nitrifying bacteria, ensuring a healthy aquatic environment from day one. Made in the USA and trusted by thousands, it’s the go-to solution for professional and hobbyist aquarists aiming for a stress-free, fish-safe tank setup.

## 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.

Review: Works well for fishless cycle. Took about a month and a half to cycle a new 100gallon tank using this. Would be better if they sold it in a smaller capacity. Took like 50gms or lesser for a full cycle. I’m left with 450gs now.
Review: Bought this for cycling aquariums. Works well. It does its job.

## 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.

*by D***S on 6 November 2025*

Doesn't come in a cup but instead a larger zip-lock package. There is A LOT of product in it and I mean a lot, I struggled to close the bag a lot. My tank was alr at 0.50 and a little less than 1/8 of a tsp raised it to 2 in less than an hour, it works very well and fast.
