| pros are increased circulation, airation which can result in a cleaner and healthier enviroment for your fish.
as for cons i cant really think of any, they might be able to suck up fry... cost money... too powerful ones can mess up fish in the current... i dunno what else.
pros are much better than the cons badness, use it
