Biological degradation of pollutants in freshwater and seawater: sintered glass biological beads for seawater filters. Simple application: simple application: use bioballs as penultimate filter stage. Intensive water purification through biological filtration: microorganisms colonize the filter media and remove pollutants. Super-efficient: optimal colonization surface of 1500 m²/l for beneficial microorganisms thanks to conical pores. Intensive degradation of ammonium and nitrite. Included: 650 g glass beads, Ø approx. 1.4 cm, with mesh bag for filling.
