What are the advantages of an external aquarium pump?
We are often faced with the end of life of an internal aquarium pump. The engine will gradually tire, run slower and slower and reject less water, because it will no longer be able to suck it in, despite the filtering part being in good condition. Algae may have developed on the turbine, turbine shaft, or internal engine parts are corroded. Usually it is the motor coil that has had its day. However, it is difficult to open the engine block to repair it without losing its seal and without risking a serious electrical problem in the home. In addition, one is often annoyed by the suction cups of the internal pump which become less effective after a year or two.
Here are the advantages of an external aquarium pump:
- freeing up space in the aquarium,
- therefore more space for fish and aquatic plants,
- less noise, as these pumps are less compact, they are much better designed,
- therefore less nuisance for fish,
- the water is better filtered, because the quantity filtered at a time t is greater,
- but also because there are more filtration steps (ceramic, bio-balls, foam, charcoal, wadding),
- possibility of coupling the filter with a bubbler to better oxygenate the aquarium,
- the parts of the appliance being wider, this type of product is easier to maintain,
- no problem with suction cups losing their property,
- possibility of adjusting the water flow,
- therefore the filter can be adapted to aquariums with different volumes of water,
- tenfold increase in life expectancy.
Disadvantages of an external aquarium pump:
- higher purchase price,
- takes up space outside the aquarium,
- need to change more filtering parts when they are obsolete.
