Fluval 5-Stage Filter, C2

The Fluval C-series clip-on filters from Fluval cause a sensation and are actually a very novel design. It has never been so easy to keep aquarium water so pure and clean. No wonder, since the C models are the first and only of their kind in the world. Users will be amazed by the result - both in terms of technology and comfort. For example, an optical cleaning indicator appears that indicates that the poly / foam insert needs cleaning. Or the suction pipe with the suction basket - it can be extended in such a way that it can be adjusted to the appropriate aquarium height.

At the heart, however, is 5-stage filtering with mechanical, chemical and biological processes.

Here are the five levels and their filter function:

1. Mechanical filtering: Porous foam traps large dirt particles.
2. Mechanical filtering: Dense polyester layer filters out fine impurities.
3. Chemical filtering: Activated carbon adsorbs undesirable odours, discolouration and impurities.
4. Biological filtering: Bio-sieve prevents dirt particles from entering the biological level.
5. Biological filtering: The biological droplet chamber with C bio nodes enriches the water with oxygen and thus ensures a quick reduction of toxic ammonia and nitrite.

Other advantages of the Fluval C series:

• Easy handling
• Durable material
• Robust processing
• Made in Europe
• Filter media are included (polyester / foam, activated carbon, bio node, bio sieve)

Oliver Knott recommends:
Pay attention to the correct dimensioning when buying a filter. For the best result, all components of an aquarium should be coordinated with each other and all parameters should fit. This saves trouble, time and money.
