Is the flow excessive with the 28? I'm using the 08 right now, and I still get good polyp movement. This is going to be a zoa and LPS tank, so I may stick with the 08 to avoid heat and sandstorm issues. I have a nice elegance that is doing very well under the LED's with a 12 hours of photo period. Just started getting some film algae though so I may dial back the light a few hours and see how the tank reacts.
