SERA - Siporax Pond Professional 25mm - 50l - Ceramic filter

Unlike other filter rings on the market, sera siporax consists of sintered glass. The unique material convinces with its special three-dimensional pore structure. This maximizes the surface area. At the same time, the fine pores create ideal conditions for colonization by bacteria breaking down harmful substances. Since it is an interconnected system, the water circulates around the bacteria permanently, so that the latter can break down harmful substances with maximum efficiency. Furthermore, the unique pore structure allows self-cleaning of the substrate and therefore very long intervals for filter maintenance.

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.
