BioMaster² 250

Easy-clean pre-filter module: no more annoying removal of the filter – the pre-filter module is simply removed, rinsed and re-inserted Increased flow rate: thanks to optimised water supply and a new connection set, the flow rate has been significantly increased in contrast to the previous model Large filter volume: the optimally coordinated combination of highly effective biological filtration by Hel X as well as mechanically biological cleaning through filter sponges ensures healthy and clear aquarium water. The water flows first through the pre-filter - for an extra long service life Longer service life: For an even longer service life, please use our biological filter media Optimal filtration: fine 30/45 ppi pre-filter sponge for optimal mechanical filtration of coarse dirt and longer service life of the biological media
