Operation and biological activation
3c First decide on a location for the filter. The filter
must stand lower than the aquarium, e.g. inside
an aquarium cabinet (1).
3d For opening the filter, pull the multi-purpose han-
dle (3.5) of the multi-purpose valve upwards. This
will close the hose valves. Now take the multi-pur-
pose valve with both hoses off the filter head (do
not bend hoses).
3e Now open the big clip locks (3.6) and lift them
from their seats. Now loosen the small clip locks
(3.7) and lift the filter head (3.8) by the small clip
locks off the filter case. Place the filter head on a
soft mat as to prevent damages of the seals.
3f You can now take the separate filter media baskets
out by their handles (3.9). The filter media baskets
are equipped for optimal pollutant breakdown.
Please note that the water flows downwards. Pre-
filter media – filter mat (floss, 2.3.1) and filter sponge
(2.3.2) – are therefore located on top, biological me-
dia such as sera siporax (2.5) at the bottom.
Rinse the sera filter mats (floss, 2.3.1) and the sera
filter sponges (2.3.2) a few times with warm tap
water without detergents before using them.
In case of strongly polluted aquarium water it is
advisable to place the black filter sponge on top
of the white filter mat (floss) as to prevent the
mat from clogging too quickly.
3g The sera siporax filter medium is included sepa-
rately. Open the bag and rinse the sera siporax. It
is best to use conditioned (e.g. with sera aquatan)
aquarium water for this purpose, as this will neu-
tralize pollutants in the tap water that are danger-
ous to micro organisms. Do not pour the water
used for rinsing back into the aquarium. Now put
the sera siporax (2.5) into the filter media bas-
ket/s.
3h Now the sera siporax is activated biologically. Drip
sera filter biostart (2.17) onto the moist sera sipo-
rax to do so.
3i Now insert the equipped filter media baskets
again. Be very careful to stack the baskets precise-
ly. The filter cannot be closed in case the filter me-
dia baskets did not snap in properly. Make sure
that all seal rings are in place as to prevent the wa-
ter flow taking a "shortcut". Fill the filter case with
accordingly conditioned (e.g. with sera aquatan)
aquarium water.
The filter case may only be filled with aquarium
water up to 4 cm (1.6 in.) below the edge, other-
wise excessive water will run out when the filter
power head is attached.
3j Put the filter head back in place. Make sure the
head seal ring lies straight and is not bent. Then
first close the small clip locks, afterwards the big
clip locks.
3k Now insert the multi-purpose valve back into the
filter (3.1) and press the multi-purpose handle (3.5)
down. The hose valves are now open.
3l ttach the intake strainer (2.14) to the intake tube
(2.13) and hang the intake strainer into the aquar-
ium on the right side (1). Connect the hose at-
tached to the "IN" side (3.4) to the intake tube.
3m Now connect the spray bar (2.10) to the 90° angle
piece (2.9) and this to the outlet tube (2.7). Use the
connector pieces (2.8) to do so. Hang the tube as-
sembled this way into the aquarium on the side of
the intake tube. Connect the hose attached to the
"OUT" side (3.4) to the outlet tube (2.7). You can ex-
tend the spray bar (2.10) with the second part.
Close the spray bar with the stopper (2.11). You
can attach the tubes and hoses to the aquarium
glass with the suction cup holders (2.15).
3n Plug in the power/mains plug when all connec-
tions are fastened. In case the filter should not
start pumping the water, use the pump handle
(3.10; types 250 and 400) or press the button (type
130) until water flow begins. The remaining air will
be pumped out of the filter case over the time.
3o Switch on the UV-C clarification by moving the
switch (3.11) to "I" after having switched on the
power/mains supply (only external filters + UV).
4. Maintenance and cleaning
The filter is the biological purification system of your
aquarium. Common detergents destroy almost all pu-
rification bacteria.
not broken down for several weeks and the animals in
the aquarium are in acute danger.
nitrivec after the filter cleaning accelerates the (new)
formation of a dense bacterial population within the
biological filter materials. While cleaning the filter, the
hoses and the running unit (rotor) should also be
checked and cleaned, if necessary.
4a Concerning filter media, "cleaning" only means
thorough rinsing with temperate, conditioned tap
water (or with aquarium water). It is best to rinse
the filter media in a bucket. You may also use water
from a water change for this purpose. The bucket
must never have had contact with detergents.
4b Depending on the fish stock, the mechanical filter
media sera filter mat (floss) and sera filter sponge
need to be cleaned weekly. These filter media
should be replaced with new ones in case of se-
vere clogging.
4c You should only clean the filter or the biological
filter media when really necessary. Necessity is in-
dicated by a very considerably reduced water flow
rate. lways clean only a part of the filter media
while doing so (see 4a), never all at once. If you do
not want to wait until the water flow rate de-
creases you may clean the filter media in the fol-
lowing intervals:
normal fish stock: every 3 to 4 months
optimal fish stock: every 6 to 12 months
Filter case and filter media baskets are only rinsed
under running water without any detergents. It is
possible that the filter is too small for the current
aquarium with its fish stock if the filter clogs more
frequently than every 6 – 9 months.
