I have always had a love hate relationship with the popular dragon acros mentioned here. They peel so fast it’s really hard to watch. This is one reason I am really a huge fan boy for using a turkey baster to keep corals clean. For the people that have never used one to blow their rocks out give it a shot and see if you can avoid clouding the tank, I bet you can’t :) Corals seemed to love the bursts of flow on them as well. To me this hobby boils down to keeping detritus in check and keeping everything as simple as possible.
