The robust protecting ball not only protects the sintered glass ring, at the same time it also improves its performance and prolongs the holding time of the filter. The water current is target directed and flows through the siporax ring even more effectively due to the unique shape and structure of the outer plastic ball. This results in maximum nutrient and oxygen introduction which increases the nitrification performance of the filter bacteria.
The new product sera siporax pond protect Professional 🔗 allows all pond keepers to ideal filter their water biologically and prolong the holding time of the filter, because the unique three-dimensional tunnel structure with plenty of pores in the sintered glass ring is not only proven to provide ideal settling conditions for filter bacteria, it is now also excellently protected against abrasion due to the protecting ball.
