Filter Housing Replacement:
The fi lter housing should be replaced with a new one once the
adsorbent is depleted. Please proceed as follows to do so:
1) Disconnect the plug-in power supply unit from the electrical
outlet. The pump will stop.
2) Open the butterfl y valve all the way and remove the suction
cups of the fi lter housing from the glass pane so that you
can take the complete fi lter housing out of the water.
3) Let the water from the fi lter housing drain either into the
aquarium or into the fi ltering basin or into a bucket.
4) Disconnect the pump and the suction cups from the fi lter
housing since you are dealing with a disposable fi lter
housing.
5) Discard the used fi lter housing in the regular household
trash.
6) Please refer to "Filter Assembly" and "Filter Installation" for
fi tting a new fi lter housing.
Notes on Best Operation:
The purpose of the ELIMI-CONTROL Filter is to remove
phosphates or yellow tint from aquarium water. Both water
components slowly concentrate in aquarium water and they
can be optimally removed using the ELIMI-CONTROL Filter.
The reduced fl ow rate ensures that the aquarium water is
completely cleaned in one cycle. Comparative tests have
shown that the fi lter material unfolds its maximum adsorption
performance to eliminate large amounts of phosphates or
yellow pigments when the fl ow rate is constrained.
We recommend to expand the ELIMI-CONTROL Basis Set by
one or several ELIMI-CONTROL Additional Cartridge without
pumps for basins that hold more than 600 litres as well as
for smaller aquaria that have to endure severe water stress.
The supplement cartridges have two hose nipples for fi lling
or draining with water and can be connected to the standard
cartridge and the pump as shown in the diagrams.
Phosphate Adsorption – ELIMI-CONTROL PHOSPHATE:
Measurements can be taken to check the effect of phosphate
adsorption. It is only possible to determine the status of fi lter
depletion long before the aquarium phosphate concentration
rises by taking measurements. Doing so ensures that the
phosphate concentration is kept low permanently before
coming to fi nd that the adsorber is depleted because of
increased concentration levels in the aquarium.
There are two different cases when it comes to the elimination
of phosphate:
- Increased phosphate concentrations are to be reduced. In this
case the fl ow rate is adjusted according to the specifi cations
mentioned above to 1 percent of the aquarium volume per
hour, 6 l/h (1.58 gal./h) at a maximum. With this setting the
phosphate content at the fi lter outlet usually amounts to
0.0 mg/l (ppm) of phosphate. The fi lter effi ciency can be best
tested in this way, even if initially the phosphate concentration
in the aquarium does not drop as fast as anticipated. The
reason for this is a "phosphate pool" in the aquarium which
typically is about three times as high than expected based on
the measured value of orthophosphates, and only these are
accounted for in phosphate tests.
- If a low phosphate concentration [0.05 mg/l (ppm) or less for
coral reef aquaria or 0.3 mg/l (ppm) or less for fresh water plant
aquaria] is to be stabilised on this low level by using the ELIMI-
CONTROL Filter, it may be useful to set the fl ow rate below
12
1 percent of the aquarium volume per hour. The aquarium
may otherwise indicate a lack of phosphates.
All organisms require traces of phosphate; 0.00 mg/l (ppm)
of phosphate in an aquarium does not suffi ce. A balance has
to be found between feeding (= source of phosphate) and
phosphate removal. Different fl ow rates effect the amount of
adsorbed phosphates. Higher fl ow rates bind more phosphates
than lower fl ow rates.
The proper functioning of the phosphate adsorber should be
checked at regular intervals by taking phosphate measurements
at the fi lter outlet and in the aquarium. The appropriate
spacing of intervals depends on the initial situation. While
taking weekly measurements when reducing increased levels
is appropriate, later on it will suffi ce to take measurements
every 2 to 4 weeks. You will fi nd out in the course of time how
long a cartridge will last in your aquarium. Start checking the
outlet more frequently at the end of the expected service life.
The phosphate adsorber is depleted if the phosphate content at
the fi lter outlet is no longer below the phosphate concentration
of the water in the aquarium. That's when the cartridge should
be replaced with a new one immediately.
We recommend to keep a record on the measurements
taken to get a general idea of the phosphate balance in your
aquarium. Use Tropic Marin Phosphate Test, art. no. 28100 to
best determine phosphate levels. You'll be able to accurately
determine the phosphate concentration from 0.03 to
3 mg/l (ppm) with this test.
Active Carbon – ELIMI-CONTROL CARBON:
When you use the ELIMI-CONTROL Filters with active carbon,
the active carbon is protected from particles and organic
biodegradable substances due to the reduced fl ow rate and
its full capacity is available for the non-biodegradable "yellow
substances". For the elimination of yellow tint it has turned
out to be of great benefi t when the fl ow rate through the active
carbon is 1 percent of the aquarium volume per hour, about
6 l/h (1.58 gal./h) at a maximum.
Experience suggests replacing the cartridge every 8 weeks
at the latest. There is no specifi c test available but you can
check for yellow tint in the water by dipping a white dish plate
halfway into the aquarium. Then look at the plate through
the aquarium. The bottom half of the dipped plate will look
yellowish if the water has a yellow tint.
Open the butterfl y valve completely if medicinal substances are
to be removed. If such is the case, the fi lter cartridge CARBON
should be replaced immediately after the removal of medicinal
substances to ensure that the adsorbed medicinal substances
are indeed removed from the aquarium for good.
