Honestly, I don't see it being enough flow for a true "wave type"/natural wave of the ocean....and the corals she has are a little deeper than the natural flow of true based "flow" type of corals that are way closer to the surface of the water types of corals...BUT, I'm not a reffer so, I am only going off of what I have seen SCUBA diving. Hopefully some of the more experienced folks may have better input.
I really don't see much of a difference between a timer (phs) and this application, other than "shallow dwelling corals"....
