    Ive been running my brand new tank for two week. Amonia was off the roof no matter how much water change Ive done (50% one day or 30% another for a 5 gal). Api quick start did squat, but this. This stuff has lowered amonia substantially over just 2 days. Im crying tears of joy lol. This was worth it and the value is amazing for this price.

    After using it as suggested within a few days, Ammonia was converted to Nitrite. However, for 2 months and 2 bottles of Fluval Biological Enhancer, it could not bring Nitrite down. Brought Tetra Safe Start and, within days, Nitrite is gone.

    Ok, I used it but didn’t make much difference until I got real IPI stuff.

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.
