Juwel Bioflow 3.0 Filter Media Set - Carbon, Nitrate, Poly Pad, Coarse, Fine

No, this is a compatible replacement set for JUWEL Bioflow 3.0 Compact Filter Units, not an official JUWEL branded product. It is designed to function effectively as an alternative.

Carbon sponges should ideally be replaced every 4 weeks, as activated carbon loses its adsorptive capacity over time and can start releasing impurities back into the water.

It is recommended to rinse sponges and pads using water siphoned from your aquarium during a water change. Using chlorinated tap water can kill the beneficial bacteria colonies living on the media.

The nitrate sponge is designed to promote the growth of anaerobic bacteria, which help to convert nitrate (a less harmful byproduct of the nitrogen cycle) into nitrogen gas, which then escapes the water.

Sponges and pads should be replaced when they start to disintegrate or become permanently clogged. Carbon sponges should be replaced monthly. The nitrate sponge can be replaced every 6 months or if you notice a decline in water quality.

Each media piece in this set measures approximately 9.5cm x 9.5cm x 1cm.

Ensure all media pieces are correctly seated and not packed too tightly. Rinse the media again if it appears clogged with dust. Check for any blockages in the filter intake or output.

Allow the filter time to work; cloudiness may be temporary. Ensure the carbon sponges are correctly placed and haven't reached saturation. If cloudiness persists after 24-48 hours, check for overstocking or uneaten food.

Gently compress the sponges or pads slightly to achieve a snug fit. Ensure you are using the correct media for the Bioflow 3.0 model and that no debris is obstructing the compartment.
