Pump
We recommend to us the
Ocean Runner 3500 as circulation
pump ( 3500 l/h).
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 respect. 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. For this
reason, the water level has be controlled and replenished regularly. The refilling can
be made easier by using the
aquaniveau
in combination with a
storage tank in order to keep the water level constant. Nevertheless, it is suitable to
mark the minimum and maximum levels directly at the tank.
