## Long description

Sera Siporax Mini 35 g is a biological ceramic filter media cartridge designed to support stable aquarium water quality. The product contains porous ceramic granules that offer extensive surface area for development of nitrifying bacteria, enhancing biological filtration. Intended for use in a range of filtration systems, this compact cartridge helps reduce ammonia and nitrite concentrations and contributes to a healthier aquatic environment.
Advantages
The porous ceramic structure of the Siporax Mini provides high internal surface area for bacterial colonization while maintaining good water flow through the media. Its compact 35 g cartridge format allows easy placement in internal filters, canister filters, and bio-towers. The inert ceramic composition does not dissolve or change water chemistry, making it suitable for continuous biological filtration without frequent replacement.
Suitable for
Freshwater aquariums requiring enhanced biological filtration
Small to medium internal and external filters
Canister filters and bio-tower modules
Systems where reduction of ammonia and nitrite is needed
When it may not be suitable
This Siporax Mini cartridge is focused on biological filtration and does not provide mechanical or chemical filtration functions such as particle trapping or active adsorption of dissolved substances. In heavily polluted systems or immediately after a major water quality incident, additional mechanical filtration, water changes, or chemical media may be required to restore water clarity and remove dissolved organics.
Key specifications
Media type: porous ceramic granules providing high surface area
Net weight: 35 g
Primary function: biological filtration to support nitrifying bacteria
Compatibility: suitable for internal filters, external filters, canister filters and bio-towers
Chemical behavior: inert material that does not alter water parameters
How to use
Place the Siporax Mini cartridge in the filter compartment where water flow passes through the media. Rinse briefly with aquarium water before first use to remove any loose dust from manufacturing. Ensure the cartridge is positioned to allow even flow and contact time; avoid placing it after fine mechanical media that could clog the granules. Monitor water parameters and replace or supplement media as part of regular filter maintenance schedules.
What to consider before purchase
Assess aquarium size and bio-load to determine the quantity of biological media required
Check filter dimensions and module compatibility to ensure the 35 g cartridge fits securely
Consider combining with mechanical or chemical media if you need particle removal or adsorption
Usage recommendations
For optimal biological filtration, use Siporax Mini as part of a layered filter setup: mechanical media first to remove particles, then Siporax Mini to host beneficial bacteria. Allow time for bacterial colonization before relying exclusively on the cartridge for ammonia and nitrite removal. Regularly test water parameters and adjust the amount of biological media according to stocking levels and feeding routines.
