Filter media:
Remove the lattice screen as well as the filter media
containers from the filter canister.
Thoroughly wash out the SUBSTRATpro or EHFISUB-
STRAT filter media with used aquarium water – until no
more clouding can been seen.
TIP:
When renewing SUBSTRATpro or EHFISUBSTRAT (the
fine pores get clogged up with time), retain at least 1/3
of used filter medium and mix with new material, to
speed-up bacteria recolonization.
Now remove the wet/dry floater compartment by opening
the two locking pins with the locking key, so that the slots
are in a vertical position.
Remove the wet/dry floater compartment and clean the inlet
aperture and both o-rings.
Open the locking ring of the
wet/dry floater compartment
in the direction indicated,
remove floating control valve
and carefully clean with a soft
sponge.
Clean all parts and wash out
the filter canister.

Wash out the filter canister. Periodically clean the
heating element from sludge. Do not bend the heating
element! Do not submerge filter canister underwater.
Protect the heater's electrics from splashing water.
Clean the connecting supports on the container and the
floater compartment (including the bypass opening) with a
brush. Reassemble the wet/dry floater compartment and
attach it to the filter canister. Take care that the sealing rings
are correctly positioned.
Place the first media container back into the canister in such
a manner that the flow-through opening sits above the con-
nection outlet which communicates with the wet/dry floater
compartment. Press the container down to the support frame
in order to guarantee a good seal with the filter canister.
Then push in the second (and third) media container. The
flow-through openings must lie on top of each other. Be sure
that the media containers have a flush fit. Place the lattice
screen.
