I feel very fortunate to have seen your tank in person at the Pacifica BAR meeting before your remodel; it was amazing. I’m sure your re-do will be also. I wouldn’t worry about having things dying in the shadows and some chaos you can’t control. That’s how the most beautiful coral reefs were formed. All the atolls of the world are made of the skeletons of corals that died because they got shaded under the growing corals above.
