Fish keeping, like life, is all about balance. Fish will only thrive when their water is in perfect harmony, with enough good bacteria available to neutralise harmful ammonia and nitrite. That's why Nutrafin have completely re-formulated Cycle, their flagship biological supplement, to make it faster, more powerful and easier to use.

Introduce Fish Immediately*
Nothing is more frustrating than staring at an empty aquarium, waiting for it to complete a fish less cycling process. With new Fluval Cycle you can now enjoy your new aquatic world straight away as the fast acting formula immediately creates a habitable environment for your fish.

Reduce Fish Loss
Cycle's new, faster acting formula gets to work immediately to quickly reduce harmful ammonia and nitrite. This means you're far less likely to lose fish in a crisis.
