Mantis Bio Filter Blocks – 2 Packs

Advanced Biological Filtration Media for Aquariums & Ponds

The Mantis Bio Filter Blocks are made from inert ceramic material with an advanced open-flow architecture, delivering one of the largest usable surface areas available for biological filtration. Compared to conventional filter media, Mantis Bio Blocks provide higher efficiency with less media required to effectively treat ammonia and nitrate.

Ultra-High Surface Area for Beneficial Bacteria

Each block features a microporous surface structure with an extremely large specific surface area, making it ideal for the growth of beneficial nitrifying and denitrifying bacteria. This promotes the formation of a stable, highly active biofilm, supporting long-term biological filtration performance.

• Surface Area: 1080 m² per block

• Supports ammonia and nitrate reduction

• Promotes rapid bacterial colonisation

3D Open Structure for Maximum Flow & Performance

The unique three-dimensional (3D) void structure allows unrestricted water flow through the block, maximising oxygen exchange and contact time with beneficial bacteria. This structure enhances filtration efficiency while reducing clogging.

Multi-Purpose Use in All Filtration Systems

Mantis Bio Filter Blocks are extremely versatile and can be used in a wide range of filtration setups:

• Sumps

• Trickle filters

• Wet / dry filters

• Hang-on-back filters

• Directly in the aquarium or pond

They also act as an excellent base for sponge growth, micro-fauna colonisation, and even coral frags.

Suitable for All Aquatic Environments

• Freshwater aquariums

• Marine reef systems

• Ponds
