Base Rock vs Cure Live Rock vs Uncure live Rock

[AJ_77]

I guess I coud be more specific. I'm referring to the greenish/greyish kind of colour that some base rock takes on instead of the purples/reds/pinks... base rock that sometimes seems to grow more indiscriminate fuzz than coraline or any neat organisms, like you say.

I know that free corals and polyps don't come on base rock, but it must be a certain type that converts so well into live rock - seeded live rock that can't be distinguished from the Fiji reef rubble that is marketed, or other "real" (and real expensive) types.

I'll have to back and find some pics of your tank, maybe from when you sold off those acros and stuff...
