Yup that's mrs Binford singing. Lol. The tank is 4ft long and 3ft deep and 22 in tall. I need to get a good video of when I feed,it shows how well the mild flow keeps things suspended. I have found allot of power heads,put out good numbers (gph) but the real issue is they have a tight stream that is departmental to the corals health. I have seen SPS actually have the flesh blown off. I really like vortech's the wide flow is not to harsh on coral and does an excellent job of keeping waste off the sand bed. I have seen mods done on older tunzes that also create excellent wide flow also.food for thought is all
