## Overview

FritzZyme 7 is a 1-gallon solution of live, species-specific nitrifying bacteria designed to rapidly reduce toxic ammonia and nitrite levels in freshwater and brackish aquariums. With over 30 years of proven success, this product accelerates biofilter cycling, supports ongoing tank stability after maintenance, and offers a convenient one-year shelf life without refrigeration, making it an essential tool for both new and established aquatic systems.

## Description

FritzZyme 7 contains specific strains of live nitrifying bacteria proven to reduce fish loss due to toxic levels of ammonia and nitrite. Nitrifying bacteria can take weeks to naturally establish colonies in new aquariums while ammonia and nitrite can reach lethal levels in only a few days. FritzZyme 7 provides the proper balance of bacteria proven to rapidly seed biofilters, greatly reducing the natural cycle time allowing for safe, immediate addition of livestock. Fritz Industries was the first company to pioneer commercial-scale cultivation of nitrifying bacteria and has remained one of only a few in the world with continuous production for over 30 years. FritzZyme 7 may be added to new tanks or established systems any time the biofilter needs fortification including: after water changes, aggressive cleaning, adding new livestock, medicating or changing filter media. FritzZyme 7 contains live freshwater-specific species of nitrifying bacteria.

Review: I'm impressed! Don't wait on getting this product! - This is my first time using this product. The reviews spoke highly of this company. I started with ghost feeding the first week, but wasn't getting as much ammonia as I wanted to begin the cycle. I got the ammonia that goes along with this bacteria in a bottle. Got the ammonia up to 4ppm 2 nights ago. Yesterday, this bottle came in, and I dosed it as recommended. This morning I did my tank parameter testing with the API Master Kit. In my cycling tank it read 2.0ppm ammonia, 0 nitrites, and 5.0ppm nitrates! It just skipped right over nitrites! That tells me this product is VERY effective! Considering it's taken me months to cycle other tanks, this is mind blowing to me. I'm glad I listened to experienced folks that using high quality ammonia and live nitrifying bacteria is FAR superior to ghost feeding. I purchased the smallest bottles they have, and I'll still have nearly all of it! Well, I guess that means I'm just going to have to get more aquariums, ha! It's so easy I'm still processing this. Don't sleep on these products, the value far exceeds their price! I'm also glad this can be used as a maintenance for established tanks. It will be a great product to have on hand to maintain a well functioning cycle.
Review: Yes! - This product at the time I purchased is valid and effective. I started a cycle for an African Dwarf Frog and had immense success. These creatures are unknown with contradictions all over the internet. They're exceptional with sensitivity that requires work. I can attest that this product worked for me when I accompanied it with a seeded sponge filter fron an established aquarium

## Questions & Answers

**Q: Would this be good for kickstarting a new aquaponics system?**
A: Yes.   It works excellent.

**Q: So just got my gallon jug in... It has a slight odor to it but its pink in color, not dark or anything...is it still good?**
A: Absolutely. I have used a lot of this stuff, and have received it in slightly brown colors all the ways to the pinkish color, and it always has an earthy odor to it. It always has worked for me.

**Q: Will it work if I put it before adding ammonia to the tank?**
A: Assume you're using the ammonia to cycle/start a new tank? Pure ammonia is not to be added if there will be fish in the tank, only when doing a fish-less cycle; the fish and their waste will supply the ammonia for the bacteria to grow and survive; be sure to keep testing the parameters of the water with a test kit; look up the nitrogen cycle

**Q: Is it supposed to be pink/purple? Thank you.**
A: I havent seen a purple color yet so far. Mine been a light to dark pink color.

### ⭐⭐⭐⭐⭐ Contains no ammonia / UPDATE
*by D***L on May 28, 2025*

My concern were the reviews that said it had “ammonia”. However, most tap water has ammonia, mine does. So I cannot test this product using tap water. Or else it would give a false positive result. Also, the smell of “rotten eggs” is a byproduct of bacteria “sulfur” - so it’s normal to smell this. For the test. I used a sample of water from an established tank that already has 0 ammonia and added FritzZyme 7 to it. Using the API ammonia liquid test, results are FritzZyme 7 does NOT contain ammonia. Looking forward to how this works on my tanks that need a fortification of BB. UPDATE: 1 week later, decided to use it on a newer tank to test its full potential and it cycled (day 1: 5/28/25 and today 6/3 final results)! Amazing! Tip, if doing IN-Fish cycle, make sure to watch any spikes in ammonia, nitrite, nirate, or PH daily. If needed do small WC, don’t mess with the substrate or filter when doing so, and let the cycle do its thing to keep your fish safe. Trust the process. This product did what it said it would do. Using it now to fortify my other tanks.
