Eheim 2012 Internal Filter
Eheim is well known for their reliable and easy-to-use pump, and the Eheim 2012
internal filter is no exception to their quality products. Designed for
aquariums which hold 25 to 50 gallons of water, this filter has a pump output of
between 57 and 148 gallons per hour. It has a volume of 0.12 gallons and uses 6
watts of electricity.
The Eheim 2012 internal filter is very easy to clean. It features a removable
filter canister that separates from the pump and cable, which stay in the tank
during cleaning. This convenient setup makes maintaining and cleaning your
aquarium so much easier.
For great oxygenization of the aquarium water, the Eheim 2012 internal filter
has a built-in air diffuser that releases a steady stream of bubbles into the
aquarium when the nozzle is pushed. Thanks to this feature you do not need a
separate air pump when using this filter.
The sponge in the Eheim 2012 internal filter functions as both a mechanical and
biological filter. It removes foreign particles and sludge from the aquarium
water, and after a period of time it will harbor beneficial bacteria which serve
to remove impurities from the water.
Because of the living bacteria that are present in the filter, it is necessary
to wash the filter with care. When you see that the Eheim 2012 internal filter
is not functioning to its full capacity, it is time to remove the sponge and
rinse it off. Do not rinse it in tap water as the chlorine and other chemicals
may kill the beneficial bacteria. Instead, simply rinse it in aquarium water
that you have removed from the tank.
You can use various filter media in the Eheim 2012 internal filter. Activated
charcoal filters can be used to remove chemical impurities such as medications
and chlorine, and chemical filters can be used to alter the quality of your
water to suit the type of fish that you are keeping in the tank.
