What is a refugium?

first live rock does not require lights, and depending on what you are
trying to protect, the refugium does not either.


Actually, this is a question I've been meaning to ask for awhile. In my 46
FOWLR, I have normal lighting, but in my 7gal nanoreef, I have PC lighting.
The live rock in my nano is quite 'live' with critters and worms and bears,
oh my. But the live rock in my fowlr has no such civilizations living on
it.

So would it be correct to say that live rock doesnt need light to support
its nitrifying bacteria culture, but high intensity light IS required for
the live rock to host a broader and more bustling segment of the food
chain?

A juvenile Naso tang, a juvenile humu trigger, and 2 blue damsels. And
yes, the tang and trigger nibble routinely at the rock (all my fish are
omnivores now). But since i never saw crawlies on the rock, i assumed
they were snacking on algaes or something, rather than the active visible
life forms in my other tank.

So I guess they're seeing them before I do, huh?
