Mechanical filter media trap suspended matter and dirt particles. This takes place at various stages:
Firstly, before the water flows through the rest of the cleaning process, EHEIM MECH and EHEIM MECHpro provide high efficiency. EHEIM FIX is the ideal material to use as a separation layer between the mechanical and biological filter media . And for fine filtration at the end, before the water returns into the aquarium, EHEIM SYNTH is the ideal material to use.
EHEIM MECH
Prefilter material made from hollow ceramic rings for trapping large dirt particles
Directly after entering the filtration cycle, water is swirled through the hollow ceramic rings. Larger dirt particles thus sink to the bottom. The treated prefiltered water then continues its way through the other filter layers. EHEIM MECH is easy to clean and reusable.
