## Summary description

## Long description

Sera SIPORAX BIO ACTIVE is a high-performance biological filter medium specifically engineered for both freshwater and saltwater aquariums. This 210g pack utilizes a unique, porous structure that provides an exceptionally large surface area for the colonization of beneficial bacteria. By facilitating efficient biological filtration, it actively breaks down organic pollutants, ammonia, and nitrites, ensuring a stable and healthy aquatic environment for your fish and plants.
Advantages
The primary benefit of this filter medium lies in its advanced material composition, which allows for rapid bacterial colonization and long-term stability. Unlike standard filter media, the active surface structure of Sera SIPORAX BIO ACTIVE ensures that beneficial microorganisms are supported throughout the entire volume of the material. This results in superior water purification capabilities, helping to maintain crystal-clear water and reducing the frequency of maintenance tasks by effectively managing organic waste loads.
Suitable for
Freshwater community aquariums
Marine reef and fish-only setups
Aquariums with high biological stocking density
New tank setups requiring rapid biological maturation
When it may not be suitable
This product is not intended for use in mechanical-only filtration systems that lack biological capacity. It is also not suitable for aquariums where chemical water treatments are used that might inhibit bacterial growth or for systems requiring specific pH-altering substrates that could conflict with the filter medium's neutral properties.
Key specifications
Weight: 210g
Material: High-porosity sintered glass
Compatibility: Freshwater and saltwater aquariums
Function: Biological pollutant breakdown
How to use
Before placing the medium into your filter, rinse it thoroughly with clean water to remove any dust resulting from transport. Place the rings into a filter bag or directly into the designated biological filtration compartment of your canister or hang-on-back filter. Ensure that the water flow is directed through the medium to maximize contact time with the beneficial bacteria. It is recommended to place the medium after the mechanical filtration stage to prevent clogging with debris.
What to consider before purchase
Ensure your filter housing has sufficient space to accommodate the 210g volume.
Verify that your current filtration system allows for biological media placement.
Consider the total water volume of your aquarium to determine if additional packs are required.
Usage recommendations
For optimal results, combine this biological medium with regular water changes and monitor water parameters frequently to ensure the biological cycle remains stable. Avoid cleaning the medium in tap water containing chlorine, as this can harm the beneficial bacteria colonies.
