OUTSIDE FILTERS 
"Outside Filters’, so-called because the filter box hangs on 
the outside of the aquarium are generally considerd super- 
ior to “Inside Filters.'’ Their superiority lies in the filtering 
principle involved. An outside filter removes the water via 
the siphon tube from the aquarium, cleans and purifies 
it through the glass wool and charcoal and returns it, splash- 
ing it on the surface of the water to further aerate it by 
means of the air-lift attached to an air pump. The distance 
the water travels, plus the greater filtering surface and 
larger quantity of charcoal it passes through, means better 
filtration versus a smaller inside filter.
