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

sera siporax pond is an effective biological filter medium suitable for nearly all garden pond filtration systems

With just 1 liter (1 US quart) of sera siporax pond, you can achieve the same settling area for beneficial bacteria as approximately 34 liters (9 US gal.) of traditional clay filter material. It's advisable to use sera biofibres coarse as a prefilter to keep larger particles from clogging the biofilter.

sera siporax pond features an extensive network of open-pored tunnel structures, providing bacteria with an optimal supply of nutrients and minimal fresh water. The oxygen-poor environment within these tunnels encourages bacteria to break down nitrate to access sufficient oxygen. As a result, they consistently reduce nitrate levels, keeping your pond water clean and low in nitrate.

One liter (one US quart) of sera siporax Professional boasts nearly the same biological filtration efficiency as 34 liters (9 US gal.) of clay filter media.
