## Summary description

AquaNatura biological filter brick sized 38×38×30 mm supplied as a 10 kg pack for aquarium and pond filtration. Designed as a porous media to promote beneficial bacterial colonization, it supports biological filtration by providing surface area for nitrifying bacteria. Suitable for use in canister filters, trickle towers, and biological filter chambers to improve water quality and reduce ammonia and nitrite levels.

## Long description

AquaNatura biological filter brick 38×38×30 mm supplied as a 10 kg pack is a porous ceramic media designed to support biological filtration in aquariums and garden ponds. The individual bricks create a high surface area for colonization by nitrifying bacteria, helping to convert ammonia and nitrite into less harmful forms and contributing to stable water chemistry. This media is suitable for use in canister filters, trickle towers and dedicated biological filter chambers where long-term bacterial growth and water flow are required.
Advantages
The porous structure and consistent brick size ensure predictable flow-through and even bacterial colonization across the media bed. Supplied in a bulk 10 kg pack, the bricks are convenient for filling large chambers or topping up existing media. Made to withstand prolonged submersion and mechanical flow, the media maintains surface integrity while providing extensive area for biofilm development and nitrification.
Suitable for
 Canister filters and modular filter media baskets
 Trickle towers and wet/dry biological filters
 Pond biological filter chambers and wetland-style filters
 Freshwater aquariums requiring stable nitrogen cycling
Key specifications
 Individual brick dimensions: 38 × 38 × 30 mm
 Pack weight: 10 kg
 Material type: porous ceramic/porous media suitable for bacterial colonization
 Designed for submerged and flowing-water applications
 High specific surface area for nitrifying bacteria
How to use
Rinse the bricks briefly with dechlorinated or conditioned water to remove dust from transport before placing them into the filter chamber. Arrange the bricks to allow even water distribution and avoid compacting them tightly; this preserves flow channels and maximizes available surface area. Use the bricks as the primary biological layer or combined with mechanical and chemical media according to the chosen filtration setup. Monitor water parameters during initial colonisation and during routine maintenance to ensure effective biological filtration.
Usage recommendations
Start with an appropriate volume of media for your filter's flow rate and bio-load: under- or overfilling can reduce efficiency. Avoid washing the media aggressively during maintenance to preserve beneficial biofilm; gentle rinsing in aquarium/pond water is sufficient. Replace only part of the media at a time to maintain established bacterial populations.
