Glass Ceramic Bio Pearls filter material made of high-quality sintered glass for crystal-clear water. Extremely porous with a huge surface area for optimal colonization with filter bacteria. Approx. 1,500 m² / l settlement surface, 10 to 12 times higher than with conventional ceramic rings! High efficiency due to low bulk density, good flow rate through the ball shape, low risk of clogging. Ideal for medium and large aquarium filters, very suitable for use in suspension filters or small filters. Guarantees rapid biodegradation of toxic ammonium / ammonia and nitrites. Suitable for freshwater and marine water.
Application: Use biofilter material after mechanical cleaning (pre-rinsing). 1 liter of "Glass Ceramic Pearls" is sufficient for 360 l aquariums with normal stocking density. In case of constant heavy feeding, proportionally less. If higher demands are required, the filter volume should be increased.
Bead diameter 8-9 mm - very high density.
