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. Calculation formula for sera siporax pond: One liter (one US quart) of sera siporax pond can effectively purify 1,000 liters (264 US gal.) of pond water, accommodating 20 pond fish each measuring 10 cm (4 in.) or a similar biomass, which is approximately 1.5 kg (3.3 lb.) of fish consuming up to 40 g (1.4 oz.) of premium food daily, while effectively reducing organic pollutants over time.
