With the help of the BIOPAC, ROLLERMAT turns from a purely mechanical filter into a complete mechanical-biological filter station. The bioballs are simply filled into the drum. A strainer stopper prevents the balls from getting back into the drain. The BIOPAC bioballs are filled with filter sponge to increase the inner surface. In the drum they quickly grow with bacteria and break down dissolved pollutants from the aquarium. The slow rotation of the drum causes the balls to move again and again so that they cannot become muddy. Too much bacterial mass formed flakes off and the bacteria remain highly active.

Scope of delivery:
