Juwel BioFlow XL

The JUWEL Bioflow Internal filter system, which has undergone several tests by independent institutions, has long been one of the world leaders in filter systems for modern aquariums and has proved its worth a million times over.

Large filter volumes and easy care

The JUWEL Bioflow filter system stands out from the crowd with its extra-large filter volumes. This gives plenty of room for excellent mechanical, chemical and biological filtering and ensures a long filter service life and longer service intervals. The filter's design offers you easy access to the pump and heater and the use of special filter cages makes it easy to remove and clean the filter media.

Excellent filtering using the bipolar current principle

JUWEL Bioflow filter system's unique bipolar current principle makes it possible to achieve different flow velocities, which helps to create the extraordinarily high filtering performance of the Bioflow system. For mechanical and chemical filtering in the upper part of the filter, a relatively fast flow velocity is particularly useful. A slower flow velocity, on the other hand, is useful in the lower part of the filter, to ensure optimum development of anaerobic bacteria, which are vital for biological filtering.

Ideal flow and integrated heater

JUWEL Bioflow filters come fitted with a highly efficient, silent Eccoflow 1000 circulation pump, with performance adjusted to the size of the filter system using scientific criteria. Bioflow Filters are also compatible for use with JUWEL heaters (Sold Seperately), which are perfectly embedded in the water circulation, ensuring an even distribution of heat through all areas of your aquarium.

Safety first – the water should stay in the aquarium!

The Bioflow filter system does not rely on hose connections which can reduce performance, often leading to leakages. The Bioflow system is the safest way of filtering the water in your aquarium.

Top-quality filter media

Every Bioflow filter system comes fitted with five top-quality filter media:

1. The poly pad catches coarse particles of dirt in the water, thereby serving as a mechanical pre-filter.

2. The carbon sponge absorbs odour compounds and turbidity as well as toxic compounds, leaving you with crystal-clear water. In this way, it acts as a chemical filter.

Optional: 3. The excellent absorption properties of Carbax enduringly and quickly bind discolorations, odours and toxic substances and ensure crystal-clear water.

4. Nitrax is a biological filter medium containing specialist micro-organisms to break down poisonous metabolites (ammonium/nitrite) in your aquarium, thus reducing the danger of fish mortality. What's more, Nitrax reduces the growth of algae by anaerobically breaking down nitrates, thus supporting the vitality of your fish.

5. The coarse sponge is used for mechanical filtering and makes it easier for bacteria to establish themselves in the aerobic zone.

Optional: 6. Cirax / Phorax / Amorax Cirax

• Cirax is an organic filter medium which creates the optimum conditions for useful bacteria to settle, due to its large, highly porous surface.
• Phorax is a highly effective filter medium used to break down phosphates in your aquarium.
• Amorax is a highly efficient filter medium made of natural Zeolite.

7. The fine sponges are used mainly for biological filtering in the anaerobic zone.
