4 litres MECHpro
Mechanical filter material:
Its unique spiral shape ensures excellent trapping of even small dirt particles. The ribbed surface structure also allows the colonisation of bacteria which break down toxins, thus guaranteeing an additional biological water cleaning.
2 litres bioMECH
Mechanical-biological filter medium for highly efficient water treatment:
Special pockets to trap dirt guarantee that both large and small dirt particles are trapped effectively.
2 litres SUBSTRATpro
Bio filter medium for best biological decomposition of toxins:
After the mechanical treatment of the water by EHEIM Mech, substrat pro offers perfect colonization conditions to the important purification bacteria through the high bulk density of the spherical shape (full utilization of the volume) and the perfect surface structure (maximum number of bacteria on each sphere). This combination provides the maximum number of purification bacteria which ensure clear, healthy water, stable water values and longer service life of the filter. substrat pro reduces the peak nitrite loads better, can be rinsed out and can be used several times.
1 x Coarse blue filter pad
Phenol free (toxic chemical normally found in other media), large pore sponge giving both mechanical and biological filtration, with even water flow-through
1 x Fine white filter pad
Fine dirt particles are traped in the fine filter pad before water re-enters into the aquarium.
