FAQ

I would like to cycle a new fishless aquarium by using decomposing food or ammonia. Can I use Fluval (Cycle) Biological Enhancer with this option?

Yes, however, we don't recommend either method. Ammonium chloride dosing usually results in excess ammonia concentrations, which prolongs the cycle and adds unnecessary pollution. If you already have a healthy aquarium, transfer some established filter media and dose with Fluval (Cycle) Biological Enhancer.

How do the nitrifying bacteria in Fluval (Cycle) Biological Enhancer survive in a sealed container?

This bacteria has been conditioned to enter a dormancy phase prior to bottling that allows it to survive with minimal food and oxygen intake. It is activated very quickly after introduction to your aquarium.

What are those small beige particles that float around my aquarium after applying (Cycle) Biological Enhancer?

These particles are called Bio Flocs, which help provide a safe environment for your fish. As per the product instructions, shake the bottle well before each use to include Bio Flocs with each dose.

    Does the job

    By grumpy48 on Sep 1, 2021

    This product does work, but please do not put fish in the same day. Follow the directions on the label, allow it to work, do your testing then go buy your fish. In my opinion a much safer way and you still cut tons of time off the initial process.

    Great Product!

    By Aquaman on Jan 20, 2020

    I have seen videos on youtube where people use this product for cycling a new tank fast. I have 3 fish tanks but all are already cycled. I used it for maintenance purposes and 1 day after using this in my 55 gallon tank I noticed the glass was cleaner. I use sponge filters so my water is always fairly clear. With Fluval cycle, my water is 100% clear. It looks like my fish are swimming in air, lol!

    Finally something worked!

    By TunasMom on Sep 11, 2019

    We have struggled for almost two months when my daughter got her goldfish. The tank water would get nasty after 24 hours, and I mean nasty. We had filters, oxygen, water treatments of every possible sort. The last thing to try was to treat the fish and not the water-enter this product! It’s been two weeks and the tank is clear, Tuna seems calmer (no flirting around spastically). Yay!

    Fluval makes the best products!

    By CSayger on Jan 18, 2019

    If you own an aquarium, you need this product. It helps get the bacterial chemistry in your tank right. Great for adding fish, water changes and setting up new tanks. Worth the money.

    Waste of money

    By AxolotlQueen on Aug 4, 2018

    I have now bought 2 bottles of this, after reading such positive reviews. Neither bottle worked. No cycle established. Had to remove my Axolotls from their big tank to cycle the old fashioned way. Thought the first bottle might have been a dud, but had no results with the second bottle, either.
