3. Set-up of the filter
The cabinet filtration system
Reef 1000
is supplied in a ready-to-use-condition in a glass tank.
This tank has the dimensions 90 x 36 x 36 cm (36 x 14.5 x 14.5 inch). 7It can be placed in the
cabinet of all standard aquaria. Because it is an open system, it should be taken care that the
cabinet is a water-proof system.
Inflow to the filter:
The plumbing from the aquarium to the filter should be performed with a PVC pipe or a flexible
tube of 40 mm (1.5 inch) diameter. The connection to the filter system is a screw connection for 40
mm pipes (enclosed). At this position, the system can be easily disconnected. It may be useful to
install a ball valve between tank and filter to avoid following water drops during the disconnection.
Suction pipe of the pump:
The pumps should be placed aside the filter tank. The suction pipe for the pump is performed with
a PVC pipe of 32 mm (1.25 inch) resp. 40 mm (1.5 inch). Also here, it is useful to install a ball
valve between filter tank and pump because the pump can be easier removed for maintenance
purposes.
Pressure pipe:
The pressure pipes of both pumps are performed - according to their capacity - either with a
flexible tube or with a PVC pipe of 20 or 25 mm diameter. In each case, a junction in one pessure
pipe has to be performed to supply the
Calcium reactor
and the
Nitratereductor
with water. It is
advisable to perform at least one part of the pressure pipe with a flexible tube (PVC silicon) to
avoid vibrations. This eliminates the transfer of vibrations from the pump to aquarium and
consequential noises.
Circulation pump:
The filter system is equipped with 2 pump suction openings for 2 circulation pumps. We
recommend to use 2 pumps with a capacity of 3,000 l/h each, e. g. Aqua Medic
Ocean Runner
3500
. The use of 2 pumps ensures the operation of the system in case of a failure of one pump. Of
course, also the filter can be operated with only one pump. This should have a capacity of 3,500 l/h
minimum. Otherwise, the two
Turboflotors
do not work perfectly (the water level in the pre-filter
chamber falls below the adjusted level).
Only use quality pumps which are saltwater resistant. Never use parts made of metal
which will come into contact with water!
4. Water reservoir - Water level in the filter tank
All open filter systems have to be planned in a way that in case of a circulation pump failure they
can take up water flowing back from the aquarium without creating an overflow. The volume of
water is depending from the construction of the overflow device, the pump capacity and the
aquarium surface. The water volume can be calculated by taking the aquarium surface (length x
width) and the build-up above the overflow level resp. the overflow comb. In most cases, the build-
up is 2 - 3 cm.
During normal operation, the filter tank can be only filled to a height that this water volume is
taken up in case of emergency. The minimum water level is determined through the height of the
pump suction opening. It has to be made sure that the pump does not suck any air. Otherwise, fine
air bubbles are blown into the water which create a lot of slurp noises. If the pump runs dry, it may
get damaged irreversibly. The water which evaporates within the aquarium is only missed in the
filter chamber - in the aquarium itself, the water level will be maintained constant. For this reason,
the water level has be controlled and replenished regularly. The re-filling can be made easier by
using the Aqua Medic
Niveaustat
in order to keep the water level constant. Nevertheless, it is
suitable to mark the minimum and maximum levels directly at the tank.
We recommend to use only pre-treated tap water (reverse osmosis) for re-filling.
