Curing live rock

[Whatigot]

I've done both, and in my moderate (especially compared to anthony) experience I was much more satisfied with the rock that I put a 4 to 6 hour light cycle on as long I was really careful to clean anything off that was dead or looked like it would die before I put it in the "cooker".
I only say this because I am a huge fan of the surprises that come in on fresh live rock and if I can help them out, why not.

Definitely much easier to just do it in the dark and I can't imagine the curing process would offer more bacteria either way.

With really nice LR, I cure in the light. With ones that have hair algae or other problems, I cure in the dark.

I too like to see what cool organisms ppo out of the rock when I get it, so unless there is a problem with the rock, they are usually kept in a lit tank or sump.
