Filter Media Cartridge Hagen Fluval BioMax 500 g – Biological Filtration Media, Compatible with Fluval Canister Filters

Hagen Fluval BioMax 500 g is a biological filtration media composed of porous ceramic-like granules designed to support colonization by beneficial nitrifying bacteria. Supplied as 500 grams of media, BioMax increases the available surface area inside canister or internal filters to accelerate the biological breakdown of ammonia and nitrite, helping maintain stable water chemistry in freshwater and planted aquaria.

Advantages

BioMax media features a highly porous structure that provides extensive surface area for bacterial growth while allowing efficient water flow. Because it focuses on biological filtration, the media helps reduce toxic nitrogenous compounds without altering water chemistry. The granules are compatible with common canister and internal filter baskets and can be combined with mechanical or chemical media for a staged filtration approach.

Suitable for

• Freshwater aquariums requiring enhanced biological filtration
• Planted tanks where stable nitrogen cycling is important
• Canister and internal filters that accept granular media
• Setups seeking to reduce ammonia and nitrite concentrations

Key specifications

• Quantity: 500 g of porous ceramic-like granules
• Function: Biological filtration media for nitrifying bacteria
• Form: Granular media with high internal surface area
• Compatibility: Suitable for use in canister and internal filter baskets
• Suitable water type: Freshwater aquaria, including planted tanks

How to use

Rinse the BioMax media briefly in dechlorinated water to remove dust before placement. Place the granules in a filter basket or media bag according to the filter manufacturer’s layout, typically after mechanical media and before any chemical media to ensure optimal biological contact. Maintain regular maintenance routines: avoid thorough simultaneous cleaning of all biological media to preserve established bacterial colonies and perform partial rinses during regular filter checks.

Usage recommendations

For best results, integrate BioMax into a multi-stage filtration setup, using mechanical media to trap debris upstream and chemical media downstream as needed. When cycling a new aquarium, allow several weeks for beneficial bacteria to establish and monitor ammonia and nitrite levels. Replace a portion of the media only when necessary, and follow manufacturer guidance for filter configuration to preserve biological stability.
