Cool to see you picture Extreme Corals - they are located about a mile from my apartment in Irving, Texas. It is on site with a store that I really like down here called Saltwater Paradise.
Anyhow, they have a freaking incredible setup. They have this 40 ft long x 4 ft wide x 3 ft deep fiberglass tank with many of their corals in it that has a amazing surge device setup on it. On on end, water exits the tank and gets pumped by one of the Sequence pumps. From there it is pumped into some variety of rubbermade like tub at the other end, above the tank. In that tub, there are about 4 toilet floater type devices.
And the amazing thing - it fills and dumps abour once a second, creating this rolling wave down the length of the tub. Freaking amazing...
