Sera Axolotl Wafers 100 ml

The breakdown of fish excretions and organic waste in the garden pond ecosystem is of great importance. Fish and koi ponds are particularly in focus, as the sometimes high stocking levels lead to significant water pollution. In the so-called nitrogen cycle, the toxins ammonia and nitrite are converted by cleaning bacteria into the non-toxic plant nutrient nitrate. A sufficiently sized settlement area for cleaning bacteria is essential for an efficient nitrogen cycle. Pond Siporax Original is a high-performance filter medium with an ideally structured surface for the settlement of (de)nitrifying filter bacteria. Its special open-pore and three-dimensional tunnel structure provides a significantly larger settlement area compared to other standard filter media, while maintaining the same filter volume. The interconnected pores made from recycled sintered glass ensure ideal water circulation within the filter material. This type of biological self-cleaning greatly extends the lifespan of the filter until the next cleaning is required.
