## Long description

AquaNatura Nano Bacteria House Square L filter media are square biological media sized 155×35 mm, supplied as a pack of 10. These units are designed to increase available surface area inside aquarium filters, promoting colonization by nitrifying bacteria that support biological filtration and the nitrogen cycle. Their compact square shape allows placement in canister filters, filter boxes and other aquarium filter systems where efficient biofiltration is needed without occupying excessive space.
Advantages
The square profile and textured surface provide extensive area for beneficial bacterial growth, improving ammonia and nitrite removal in freshwater and marine aquaria. Manufactured from inert, non-toxic material, these media do not affect water chemistry while offering durable structure that withstands regular flow and handling. Supplied in a convenient pack of 10, they allow staged replacement or expansion of existing bio-media beds to maintain stable biological filtration capacity.
Suitable for (tasks / use cases)
Biological filtration in canister filters
Use in filter boxes and media baskets
Support of nitrification in freshwater and marine aquaria
Rebuilding or expanding biological media compartments
Key specifications
Shape: square
Dimensions: 155 × 35 mm
Quantity per pack: 10 pieces
Material: inert porous polymer (non-toxic)
Application: biological filter media for aquaria
How to use
Rinse each unit briefly with dechlorinated water to remove any loose particles before placing into the filter. Position the media in the biological section of a canister filter, filter box or media basket ensuring water flows evenly through the units to maximize bacterial colonization. When installing in layers, avoid compacting media too tightly to maintain good water circulation and oxygen access for nitrifying bacteria. For new setups, allow time for bacterial populations to establish before relying on full biological filtration performance.
Usage recommendations
Replace individual units gradually rather than all at once to preserve established bacterial colonies; inspect periodically and clean by gentle rinsing in aquarium water if clogged. Monitor ammonia and nitrite levels after installation and during maintenance to verify effective biological filtration.
