Good post Darren.
One thing that I came upon in my reefboard wanderings was Jerel's lighting schedule. He runs his MH in short bursts and is experimenting with increased growth with less light. Basically, he points to the amount of energy a coral must use to protect itself from the UV radiation and is trying to find the line of balance where there is actually too much light in regards to growth. The point where the coral begins expending more energy protecting itself than growing. This would be an expensive endeavour however, as you would seriously jeoprodize the life of the bulb. He offsets this by using electronic ballasts and being rich (apparently). I realize this is a little off topic. My reason for posting this is that our closed systems don't mirror [img]images/smiles/icon_smile.gif[/img] the real world for a number of reasons.
