Pro's include excellent aeration of the water, excellent filtration. Cons are that they tend to be expensive, big and noisy. Most other filters just flow water over submerged filter media. Lots of variants, but essentially they all work the same. You pump water over some filter media that provides large surface area for aerobic bacteria that break down toxics like ammonia. This is usually preceded by a mechanical filter or filter stage, such as a vortex, sieve, or a chamber with brushes or matting to keep the biggest debris out of the biological stage. [/QUOTE]
