3DM Octas Ceramic Biological Filter Media (9 x 3 cm)

Achieve pristine water quality and a perfectly balanced aquarium ecosystem with the 3DM Octas Ceramic Filter Media, available now at www.onyxaqua.com. Engineered for maximum biological filtration, this highly porous, gear-shaped ceramic media provides an incredibly vast surface area for beneficial bacteria to thrive. Supporting a robust nitrogen cycle, it ensures a safe, toxic-free environment for your most sensitive fish and invertebrates.

Due to its large 9x3 cm size, this media is the perfect biological powerhouse for sump systems, large canister filters, trickle filters, and koi pond filtration setups.

Key Features & Benefits

• Maximum Surface Area: The highly porous, pumice-like 3D structure combined with the unique 8-point "octa" star design massively increases the surface area available for nitrifying bacteria to colonize, far outperforming standard smooth ceramic rings.

• Optimized Water Flow: The gear shape and central hollow core prevent the media pieces from packing too tightly together. This ensures a steady, uninterrupted flow of oxygen-rich water through your filter, preventing harmful anaerobic dead zones.

• Superior Biological Filtration: Houses massive colonies of beneficial bacteria that actively and rapidly break down lethal ammonia and nitrites into easily manageable nitrates.

• Completely Inert: Made from high-temperature sintered ceramic that will not alter your aquarium's pH, KH, or overall water chemistry.

• Highly Durable: The solid, baked ceramic construction will not crumble or degrade underwater, making it a permanent, long-lasting biological media solution.

Installation & Maintenance Pro-Tips

To get the most out of your 3DM Octas Ceramic Media and maintain a healthy tank, follow these best practices:

Pre-Rinse: Before placing the media in your filter, rinse it thoroughly under tap water to remove any ceramic dust created during manufacturing and shipping.

Strategic Placement: Always place your biological media after your mechanical filtration (like sponge pads or filter floss). This prevents the microscopic pores of the ceramic from getting clogged with solid fish waste and debris, allowing the bacteria to breathe.

Safe Cleaning: Biological media rarely needs cleaning. However, if it becomes heavily covered in sludge, gently swish it in a bucket of siphoned aquarium water. Never wash this media under untreated tap water, as the chlorine will instantly kill off the beneficial bacteria that keep your aquarium cycled and safe.
