    Does the trick and works wonders, I always use this when setting up a new aquarium. While you can add fish immediately after dosing with this as it says, I would still wait at least overnight to give the bacteria a chance to get going. Dont forget to shake before each use because the bacteria cultures will settle to the bottom of the bottle.

    Where was this 15 years ago? When we first started an aquarium, no one told us about how the water needs to cycle to get the good bacteria established, so we lost a lot of fish. Once we figured that out, it made life easier- this even more so. We have been added it at water changes and I think it has done a lot to keep our tank healthy.

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.
