Cylindrical Filter Media Tube
These Cylindrical Filter Media Tubes are designed for aquarium and pond keepers who want to significantly boost biological filtration capacity using a proven, high-surface-area media. Supplied in boxes rather than individual pieces, they’re ideal for new setups, filter upgrades, or heavily stocked systems that need stable, long-term biological support.
Each tube is 18 cm long and made from porous ceramic material, providing an extensive internal and external surface for beneficial nitrifying bacteria to colonise. The open cylindrical design allows water to flow freely through the media, maximising contact time and improving the breakdown of ammonia and nitrite for cleaner, healthier water.
Key benefits
• Porous ceramic construction offers exceptional surface area for beneficial bacteria
• Supports efficient biological filtration in aquariums and ponds
• Free-flowing cylindrical design improves oxygenation and water contact
• Supplied in bulk boxes for larger filters and bio chambers
• Durable, long-lasting, and reusable media
How to use it
Rinse the tubes thoroughly with aquarium or pond water before use. Place them into your canister filter, sump, or pond bio chamber where water flow is steady but not overly turbulent. For best results, combine with mechanical filtration such as sponges or filter floss to prevent debris from clogging the pores.
