I haven't gotten all the through the book yet. One thing that keeps coming to mind is the fact that corals are desinged to feed. I personally think that feeding is more important than light. When I look at pictures of peoples tanks with the MH lighting the corals are doing fine but are long and thin. I believe that with good lighting ( not 400watt MH) and target feeding the corals would do better. I think that the corals under high MH lighting are doing well is because of the zooantellae are growing more than they should be trying to get as much energy from the light as possible because thats all they get. With proper nutrition I think the corals would be heathier and live alot longer than ones that are placed under MH lighting only or with little food. You just have to look at all those polyps on the corals and think that they are a food machine more that light assorbing. If they only needed light, there would be far fewer polyps and more surface area to collect light not food. JMO
