Is it possible with two different reefwave25's to alternate one going and then stopping and then the other one going. Because I have two of them and I would like to place them both at the top pointing at each other but if I do it right now it will of course just point all flow to the center and go down from there when they meet versus allowing one side to go and the otherside to wait/go in the reverse order. If anyone has an idea of how to do this please let me know!
