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.
