Aquarium filters in general help generate flow, absorb substances that causes turbidity, and enrich the water with oxygen. Beneficial bacteria that settle within the unit’s filter media help to break down and remove waste from aquarium inhabitants. External filters typically have different types of filter media in several layers throughout the filter unit. These filters operate outside of the aquarium and can be conveniently stored in a cabinet under the aquarium, making them easily accessible for maintenance.

OASE’s Thermo line of BioMaster and FiltoSmart filters have the added feature of an integrated heater. By integrating the heater into the filter, the amount of additional equipment seen in the aquarium is reduced.

TIP! The basis for the selection of an aquarium filter is the size of the aquarium, measured by the amount of water. In general, it is better to choose an oversized filter system than a small one.

 

TIP! Be patient... 

Important microorganisms that biologically clean the water settle on the filter foams in your aquarium filter. These microorganisms feed on minute particles that we perceive as debris - a new or recently cleaned filter only attains its full performance capacity gradually; the microbiology must first establish itself.
