I have been tossing around the idea of going with external overflows myself but after doing some research on the subject I have come up with two conclusions. External overflows can possibly fail and dump water on to the floor. Also they do not move as much gallonage as internal overflows which means you cannot run a large return pump without having to limit its flow or you risk overflowing the tank. The other reason I am not as fond of external overflows is because I want to place the tank as close to the wall as possible for aesthetic reasons. These are only the conclusion that I have come up with and I certainly do not consider myself an expert on the subject or I wouldn't have started this post.
