sera siporax pond Professional 25mm - 2Kg

Sera siporax pond is a 100% biological filter media for all garden pond filters

1 liter of sera siporax pond offers the bacteria as much colonization surface as eg 34 liters of clay filter material. Use sera coarse biofibers as pre-filtration material to avoid coarse soiling from suspended solids.

sera siporax pond offers the bacteria a large number of open-pore, tunnel-like structures, which allows them to benefit from an ideal nutrient supply for small amounts of fresh water. Inside the tunnels there are conditions with low oxygen content, which encourages bacteria to break down nitrates to receive enough oxygen. Thus, they continuously decompose nitrates and the pond water remains low in nitrates.

1 liter of sera siporax pond has the same biological decomposition capacity as approximately 34 liters of clay filter material.

Calculation formula for sera siporax pond:
A single liter of sera siporax pond is sufficient to permanently clean 1,000 liters of pond water with 20 fish of 10 cm in length or a similar population (corresponding to approx. 1.5 kg of fish and a feed of up to 40 g of quality food/day) organic pollutants.
