Sera Siporax Professional 15 mm - 14.5 kg

The original sera siporax Professional is suitable for use in freshwater and saltwater aquariums, as well as in ponds.

Regardless of the filter type (internal, external, trickle), it maximizes the surface area necessary for biological cleaning, providing the optimal substrate for colonization by essential filter bacteria.

In nature, filtration and decomposition processes play a fundamental role.

Organic waste is broken down by microorganisms, making it available again in the natural cycle as nutrients for aquatic plants.

Harmful substances such as ammonium, nitrites, and nitrates are eliminated.

Since the amount of waste generated in nature is small in relation to the volume of water, the surface of the bottom is sufficient to harbor enough microorganisms.

However, an aquarium is a small biotope in a confined space.

To ensure the complete and safe decomposition of organic waste, it is therefore necessary to maximize the colonization surface area.

This is what sera has achieved perfectly with the help of the extraordinarily ultra-efficient filter medium, sera siporax.

Unlike other filter rings on the market, sera siporax consists of sintered glass.

The unique material is impressive due to its special three-dimensional pore structure.

This allows for the maximization of the surface area.

At the same time, the fine pores create ideal conditions for colonization by bacteria that break down harmful substances.

Because it is an interconnected system, water continuously flows around the bacteria, allowing them to break down harmful substances with maximum efficiency.

Furthermore, the unique pore structure allows for self-cleaning of the substrate and thus, very long intervals between filter maintenance.

In combination with specialized bacteria, sera siporax also allows for a multitude of special applications, such as algae prevention or targeted water conditioning.
