Juwel Aquarium BioPlus fine filter cartridge, compatible with multiple JUWEL tanks, 95×95×45 mm

BioPlus fine by Juwel is a replacement filter cartridge designed for freshwater and seawater aquariums. Sized 95×95×45 mm, this fine-pore cartridge is compatible with multiple JUWEL tank models and fits into JUWEL filter housings to provide mechanical filtration and support for biological processes. The open, chemical-free pore structure creates a large surface area that promotes slow and even water flow, making the cartridge suitable for use in the aerobic and sub-aerobic zones of the filter where beneficial bacteria colonize.

Advantages

The cartridge traps small suspended particles and soft debris while providing an extensive surface for colonization by nitrifying bacteria, supporting biological filtration. Its fine pore structure ensures uniform flow and reduces channeling, and the material is produced without chemical additives to avoid residue release into the aquarium. The standardized 95×95×45 mm size allows straightforward replacement and compatibility with several JUWEL filter installations.

Suitable for

• Freshwater aquariums requiring fine mechanical filtration
• Seawater and marine tanks needing biological support
• JUWEL tanks that accept 95×95×45 mm cartridges (Primo, Rio, Trigon, Vision, Lido and similar models)
• Filter setups where slow, even water flow and large bacterial surface area are desired

Key specifications

• Dimensions: 95 × 95 × 45 mm
• Material: fine-pore filtration sponge with open pore structure
• Filtration type: mechanical fine filtration with biological colonization support
• Chemical-free manufacture: open pores formed without chemical additives
• Intended use: replacement cartridge for internal aquarium filter systems

How to use

Turn off the filter and remove the old cartridge according to your aquarium model’s instructions. Rinse the new cartridge briefly in dechlorinated water to remove any loose particles and insert it into the filter housing in the same orientation as the previous media. Restart the filter and check for correct seating and flow. Replace the cartridge on a regular schedule based on bio-load and water clarity; inspect it periodically and rinse gently in aquarium water to preserve beneficial bacteria when appropriate.

Usage recommendations

For stable biological filtration, avoid replacing all biological media at the same time; stagger changes to maintain bacterial populations. Rinse the cartridge only in aquarium water and not under chlorinated tap water. Monitor water parameters after installation and adjust maintenance frequency according to stocking level and feeding practices.
