Just received my Tunze Turbelle Stream pump model 6110 with single controller from Champion. I love it! I mounted it against the back corner of my 6' X 4' X 36" tall tank. It is blowing across the top of the reef diagonally to the opposite corner. It creates amazing flow. They are absolutely correct in saying that it has high flow with no "blast" effect. I have it set such that there is high flow (?12,000 lph or 3000 gph) for 5 seconds and then lower flow for another 5 seconds. Just like wave action. Hopefully, it does not die within a few months like most of the powerheads that I have used in the past. Interestingly, which I did not know when I bought it, is that the propulsion is created by a little propellor blade, unlike the impellor in most other powerhead type pumps. It is like a mini, encased electric trolling motor. So far, I would highly recommend it for those of you that want to spend about $350. It is much better than 10 RIO's, believe me!!
PS. I do not work for Tunze or Champion Lighting, and am not an investor in those companies either.
