We have a Canon 40D over here... I might... MIGHT have to invest in the macro after seeing how well it does.

It is for our Graphic Design/Photography business we have.... macro might be a nice addition to the arsenal!

Olympus 6000.... I almost bought that one as well... went with the Pentax W90... might have to drop it in the tank and see what comes of it

Thanks!

Interesting that one coral "browned out" while others were dying off.

Browning is a typical sign of high nutrients, isn't it?
Perhaps the mucus secretion from your LPS and soft corals had increased suddenly for some reason leading to a high level of dissolved organics, plus some added chemical warfare happening at the same time.

Were you adding any corals shortly before that "event" or fragging anything?

Actually there was more than one that browned out. Mostly all of the surviving SPS (50% of them) browned out to some degree. Some receded from the bottom some from the tips. Some STN'ed some RTN'ed. No fragging was done. Yes a few corals were added just prior. Yes what you suggest is certainly a possibility among a laundry list of other possibilities. In the end Im leaning towards the cause not being one thing but rather a cascade of events probably.
