Eheim media set Prof3 1200XL

In the kit:
2x 2 liters EHFIMECH
Mechanical filtration with EHFIMECH: effectively captures and removes all coarse dirt particles from the water during further filtration.

1 Coarse filter (blue sponge)
It does not contain phenols (toxic chemicals commonly found in other environments), a sponge with large pores that provides both mechanical and biological filtration with a uniform flow of water.

4x 2 liters of SUBSTRATpro
Biofiltration with SUBSTRATpro: Excellent micropore structure for rapid colonization of the necessary bacteria to achieve faster decomposition of toxins. The pearl structure, which prevents clogging, ensures better flow flow, increasing efficiency by 50% by increasing the intervals between cleanings. Non-abrasive

1 filter fleece (white cotton wool)
Fine dirt particles are retained in the fine filter before the water enters the aquarium again.
