Sera Siporax Pond Professional 10Ltr (15mm) (2.9Kg)

Sera Siporax Pond is a fully biological filter material suitable for almost all garden pond filters.

Sera Siporax Pond with a capacity of 1 liter (1 US quart) offers a bacterial settlement area equivalent to approximately 34 liters (9 US gallons) of clay filter material. It is preferable to use coarse biological fibers from Sera as a pre-filter to prevent large particles from entering the biological filter.

Sera Siporax Pond provides bacteria with a vast amount of open-pore structures. This allows for optimal nutrient supply to bacteria and minimal fresh water. Oxygen-poor conditions exist inside the tunnels, causing bacteria to decompose nitrates to obtain sufficient oxygen. As a result, they continuously decompose nitrates, keeping nitrate levels low in pond water.

The surface of Sera Siporax Professional has a biological decomposition capacity equivalent to approximately 34 liters (9 US gallons) of clay filter material.
