Roger-- I have a bare bottom 58 Oceanic sps tank and was considering the 6010 stream w/controller. I have a 3/4" sea swirl in the back right corner and the overflow box is in the back left. I was thinking of putting the stream in the back left corner (between overflow box and back glass) shooting it slightly diagonal to front center glass & letting it bounce around from there. What would you suggest & can you mount them in a corner or does the mount have to lay flat? Thanks! The Tunze factory slide show is fascinating btw.
