Suitable for internal and external filtration units, media chambers, and sump use.

## Long description

AquaNatura Biological Filter Brick media 38×38×30 mm, 0.5 kg consists of porous, ceramic-like bricks designed to support biological filtration in freshwater and marine aquaria. Supplied as a 0.5 kg pack of uniform 38×38×30 mm bricks, the media provides extensive surface area for colonisation by nitrifying bacteria, helping convert toxic ammonia and nitrite into less harmful nitrate. The compact brick shape makes the media stable in media chambers, sumps and many internal or external filtration units.
Advantages
The porous structure delivers a high surface-to-volume ratio for efficient bacterial colonisation while allowing water flow and oxygen penetration. Bricks are chemically inert and do not alter water parameters, making them suitable for both freshwater and marine systems. Their regular 38×38×30 mm format simplifies packing, replacement and measurement of media volume in filter chambers or sumps.
Suitable for
Biological filtration in home freshwater aquaria
Marine and reef aquarium filtration setups
Use in media baskets, filter cartridges, sumps and external canister filters
Establishing or boosting nitrifying bacteria colonies during cycle-up or maintenance
Key specifications
Pack weight: 0.5 kg of filter bricks
Brick dimensions: approximately 38 × 38 × 30 mm
Material type: porous ceramic-like media with high internal surface area
Application: biological filtration for freshwater and marine aquaria
Form factor: solid bricks suitable for media chambers and baskets
How to use
Rinse the bricks in dechlorinated water or aquarium water before initial use to remove any dust from packaging. Place the bricks in a filter media compartment, media basket, or sump where water flows freely through and around them to maximise bacterial colonisation. Maintain consistent water flow and oxygenation; avoid compacting the bricks tightly against one another to preserve flow paths. Replace a portion of the media periodically during maintenance if clogging or excessive detritus accumulation reduces flow, while retaining some older media to preserve beneficial bacterial colonies.
Usage recommendations
For optimal biological filtration, combine these bricks with mechanical pre-filtration to prevent rapid clogging. During aquarium cycling, monitor ammonia and nitrite levels regularly and retain a fraction of colonised media when performing full media changes to maintain established bacteria.
