I have two RW8s in my 150 gallon tank that is 6 feet long. I have them on one of the pulsing wave modes (forget what it's called). I have them dialed up to max and the wave they make is just perfect as the crest comes up to about 1/4 from my eurobrace. I thought about the RW15s but I would have to dial those down a tonne, so the 8s are perfectly fine for me.
