Filter Media Maxspect Nano-Tech Bio-Sphere Negative ION– 1 kg

Maxspect Nano-Tech Bio-Sphere Negative ION is a high-performance biological filter media designed for freshwater aquariums. It uses an inert porous ceramic base combined with a special mineral formulation that releases negative ions. The highly porous spherical structure provides a large surface area for beneficial nitrifying bacteria to colonize, supporting biological filtration and helping maintain stable, clear aquarium water.

Key Features

• Negative Ion Technology: Special mineral ingredients release negative ions to help neutralize aquarium water and support a pH range of approximately 7.0–7.2.
• High Surface Area: Each Bio-Sphere provides up to 54 m² (580 ft²) of surface area for beneficial bacterial colonization.
• Excellent Biological Filtration: Supports colonies of nitrifying bacteria that help maintain water quality and biological stability.
• Improves Water Clarity: Encourages healthy microbial colonies and helps maintain clearer aquarium water.
• Durable Ceramic Construction: Made from stable, inert ceramic material and fired for over 6 hours for strength and long-term durability.
• Compact & Efficient: The spherical design provides a high filtration surface area while occupying relatively little filter space.
• Versatile Application: Suitable for canister filters, HOB filters, sumps, or other areas with good water flow.
• Easy Maintenance: Can be placed inside a mesh media bag for convenient installation and cleaning.
• Freshwater Use: The Negative Ion version is specifically designed for freshwater aquariums.
