Product Specification

  • Canister filters for aquariums use high water pressure, from a properly powered pump, to force water through the dense filter media. A pump can draw water from an under-gravel filter, and run it into a canister for double filtration
  • 3 or 4 media trays (depends on the model) capable of handling your choice of filtration media; Comes with an adjustable spray bar.
  • This is a helpful feature if you want to adjust the output flow from the filter
  • Convenient self-priming pump that eliminates the need for manual siphoning; Single valve disconnect & priming pump ease routine maintenance.
  • Provides quiet, efficient filtration for fresh and saltwater aquariums

 

Filter operation and problem solving

Noise reduction/ external air

Especially the suction intake /inlet and the connected suction surface must be checked for tightness and adjusted according to the water level of the aquarium. In case this is not possible due to aquarium technical reasons, seal the whole suction surface so that no external air can get into the filter.

De-aerating/ evacuating air

Take the return-flow hose that conducts the water from the filter to the tank and lead it into a clean bucket that is placed below the filter. Lead the hose into the bucket and carry out the dearation process (evacuate the air) by activating the manual pump. Please make sure that the possible maximal flow is adjusted to the inlet-outlet connector. As soon as no air bubbles can be seen, seal the hose with a finger und and install it again as intended on the return pipe at the top edge of the aquarium.

Leakage after installation or cleaning

In case of a slight leakage still persists after the installation or the cleaning of the filter, this indicates that the problem is most likely the sealing between the hose connector adaptor and the filter head (cover lid) The plug-in adaptor, to which the hoses are connected, has on the lower side two O-rings that must seal the connection inside the filter lid. If these O-Rings are dirty, displaced (out of place) or damaged they cannot seal properly anymore and water escapes in the filter lid/cover of the aquarium filter. The leak point is then the lowest point of the filter cover/lid and appears typically at the lateral clamping points that connect the cover lid with the filter tank/canister.

The remedy is here as simple as the failure itself. You have to rinse and check the O-rings. Make sure that the spots where the O-rings have to be inserted and positioned are free of dirt. On these particular spots algae formation can appear and impair or damage the O-rings’ sealing if no regularly cleaning is carried out. This problem can also appear in case of a new installing because of sand, for instance.

Please allocate sufficient time for rinsing and cleaning; if this is not done carefully and thoroughly, it can happen that the aquarium canister filter still leaks after the O-ring sealings have been cleaned. If, despite a thorough cleaning the water leakage at the above-mentioned spots still persists, you must check the O-ring seating inside the adaptor. This requires opening the inlet/outlet adapter.
