Product information

Description

sera Siporax Bio* active Professional 35 g is a biological filter media made from highly porous ceramic material engineered to support nitrifying bacteria in aquariums. Supplied as 35 grams of granulated Siporax, this media increases surface area for microbial colonization, helping to reduce ammonia and nitrite levels and stabilise water chemistry in both freshwater and marine systems. It is intended for use in internal and external filtration units and can be combined with mechanical and chemical media to form a complete filtration regimen.

Advantages

The porous structure of the Siporax granules provides a large effective surface area for beneficial bacteria, promoting efficient biological filtration. Its ceramic-like composition is chemically inert and durable, maintaining structural integrity over long operational periods. The media is supplied in a measured 35 g portion suitable for small to medium filter chambers, and it does not compact easily, maintaining flow-through and oxygenation for microbial colonies.

Suitable for

  • Freshwater aquariums with community fish, planted tanks and shrimps
  • Marine and reef aquaria for biological nitrification support
  • Internal sponge filters, canister filters and small external filtration units
  • Startup of new aquariums or boosting biological capacity after maintenance or stocking changes

Key specifications

  • Material: porous ceramic/ceramic-like granulate
  • Form: granules suitable for filter baskets and media chambers
  • Weight: 35 grams per pack
  • Function: biological filtration promoting colonisation of nitrifying bacteria
  • Compatibility: suitable for both freshwater and marine systems

How to use

Rinse the Siporax granules briefly with aquarium water to remove dust before placement; avoid using tap water with chlorine. Place the 35 g portion in a dedicated media chamber, filter basket or permeable bag within the filter unit, ensuring water flows evenly through the granules. Combine with mechanical filtration (sponges or floss) upstream to prevent clogging and with chemical media downstream if needed. Do not clean the media vigorously; when necessary, perform gentle rinsing in aquarium water to preserve beneficial bacteria.

Usage recommendations

For reliable biological stability, use Siporax Bio* active Professional as part of a multi-stage filtration setup. In heavily stocked or larger aquaria, increase the quantity of biological media proportionally. After major water changes or filter maintenance, allow time for bacterial recolonisation and avoid complete replacement of all biological media at once to prevent disruption of the nitrification cycle.
