Juwel Filter Pads for Juwel Bioflow M Filter

Keep your aquarium water crystal clear and healthy with a complete, high-performance filter media set designed for mechanical, biological, and chemical filtration. Each component works in harmony to optimise flow, boost beneficial bacteria, and maintain pristine water quality in both freshwater and saltwater setups.

The coarse-pored blue sponge offers a large surface area and even water flow for efficient aerobic biological filtration, while its homogenous structure ensures stable, reliable performance. Manufactured without chemical additives, its open pores are residue-free and safe for aquatic life.

The fine-pored blue sponge complements this by housing vital bio-cultures that help effectively clean the water. For best results and to preserve the biological balance, clean or replace one sponge at a time at recommended intervals, following your system’s maintenance guidelines.

As a mechanical pre-filter, the white filter wool traps coarse debris before it reaches the rest of the media. Made from fine, residue-free polyester, it protects downstream stages from rapid soiling and extends cleaning intervals—ideal for reducing maintenance effort.

For targeted nutrient control, the biological nitrate-reducing medium promotes the breakdown of ammonium, nitrite, and nitrate. This helps curb algae growth, support plant health, and increase the vitality of your fish by stabilising water parameters through purely biological activity.

To polish the water, the activated carbon sponge absorbs odours, discoloration, turbidity, and harmful compounds, ensuring sparkling clarity and a healthier environment. Its sponge form guarantees even flow and a highly effective surface, and it’s especially useful for removing residual medications after treatments.

Key benefits:
