Jbl Bionitratex

Biological filter material which is degraded by bacteria to remove algae-promoting nitrate from freshwater and marine water
Just add filter material to internal or external filter and only refill when it has been degraded by the bacteria after approx. 6 month
Bacteria settle on the bio balls and form a thick biofilm. Underneath the oxygen level drops, so that the bacteria there can remove oxygen from the nitrate and thus degrade it
Water stabilising effect: since pH decreasing acids are created during the bacterial degradation processes, the bio balls contain acid binding minerals to stabilise the water
Package contents: 100 bio balls for the nitrate breakdown in 200-300 litres aquarium water; 1 ball / 2-3 litres of water
