Several updates:
1. Does anyone know of a diver, or can you post on a site with divers, who can take some pics and videos of reef water? What is needed is this: The diver takes a camera and a piece of black cloth/plastic/etc to a reef location; he holds the black sheet about 24 inches from the camera, and takes hi-res pics and video of the plankton floating between the camera and the sheet. Hi-res would be important because of the small particle sizes. Being near corals would be important because that's where the corals feed. And doing it at night would be a great plus, since that's when more plankton is out. Daytime will suffice, however. The purpose of this is to show that reefs really are packed with food particles, and are not "polished" the way reefers "think" they are.
2. Replace bulbs every 3 months, even when they look fine.
3. Clean pump in vinegar every 6 months, even if you think it runs fine.
4. "Turf" is not the goal; Green hair is the goal. It filters the best, because it lets light get to the roots, and it lets water flow throughout the strands. If you start getting real turf, remove it with a hacksaw blade:

5. The two most important quotes I've found so far:
"Where deep lagoons are formed, coral growth, especially of Acropora, can be prolific"
"Contrary to popular belief, species diversity is not at its highest on the scenically attractive reefs found in clear oceanic water. It reaches a peak for any given region on fringing reefs protected from strong wave action, where the water is slightly turbid."
-- Corals of the World, Vol 1 page 27
Why? Because it shows that there is more coral growth in lagoon areas than on reefs. How is this? Since lagoons have more algae, they have less nutrients, and more organics (food), than reef fronts (data easily found in reference studies). And that's what corals, especialy SPS, need to grow. Reef fronts (where mostly Acro's grow) actually have higher nutrients and lower organics (food) than lagoons. Why then are there mostly Acro's on reef fronts? Because Acro's don't break under wave action like other corals, and therefore Acro's have less competition (also taken from Corals of the World, Vol 1 page 27).
