I have a 30 gallon breeder with the short side as my back so its like an island tank. The Vortech has one side in and out of the aquarium. I had to move the tank out 5 -6 inches from the wall so i can get to it. Its way to far out from the wall now. And the doesnt give me the right flow
Also since im going with the controllable koralias i can have two different directions of flow. To do that with vortechs id need 700 bucks.
