    I started trying to cycle a brand new tank with API quick start (I had only used API stress-zyme previously for maintenance) but decided to use quick start since I was setting up a new tank. I had serious new tank syndrome and lost 3 fish within a couple days. My nitrites were through the roof no matter how much of a water change I did. I used this from Fluval, and I swear within 24 hours all of my levels were 100% perfect. I did a second test because I was skeptical. I did nothing to my tank that day but add more of this from Fluval, and did another test 24 hours later and my levels were still perfect. I will never use another biological enhancer but this from now on!

    I add this but it seems like these products never really do anything extra for fish tanks.

    I set up a 10 gallon shrimp tank and after doing literally everything i possibly could to ensure the shrimp would survive when they came, but i forgot one crucial thing i guess, to CYCLE the tank. i had no clue what that was until i did some more research but this product saved my you know what, my shrimp too! this stuff works, and fast.

    Update- I crashed my cycle and used this (Fluval Cycle) am Am Guard while I was out of town (friend and mother helped) using Fluval and the tank was cycled in 12 days. Much better than the 8 weeks! I use this product on all my tanks around once a day. I also use the Fluval waste control stuff they sell, I can’t think of the exact name but it deals with waste. I also use Fluval water conditioner and I haven’t had any issues with that. I’ve tried a lot of products from different companies and I like the Fluval and I use some Seachem stability with water changes too. This stuff will help cycle the tank quicker

    It not only is boosting my tanks bacteria, but even helped with a bacteria bloom.

Fluval Cycle Biological Enhancer is a responsive biological aquarium supplement that ensures that all aquariums are immediately inoculated with a powerful team of beneficial bacteria, providing a safe biological habitat for your fish. These highly effective micro-organisms will create a biological flora that quickly metabolizes lethal ammonia and nitrite and allow for the immediate introduction of fish. Fluval Biological Enhancer goes to work fast, releasing massive amounts of beneficial bacteria that eliminate toxic ammonia and nitrite to establish a biologically-balanced aquarium. Fluval Biological Enhancer is strongly recommended for new aquarium set-ups and regular application will help to exclude the establishment of undesirable bacteria in aquariums.
