[sfl01208]

Is this green coraline? I saw it on an ID thread earlier and thought it was, then a friend saw it and told me to quite smoking...its all along the glass
and then there is this other green thing on the rock, was told it was a sponge but only got one response maybe someone else will tell me its a sponge too!! lol

Yes the first pic is green coralline algea. No idea as to the second pic.

I use to get green but some how it died out and the purple took over. Just get some purple to spread it. I think the second one is the plate coralline but this is the first time I saw green one.

Like Dragonboy said, buy a piece with some nice purple growth and scrub it while it is in the tank. Do that in front of a powerhead. Just sit back and let it grow.

The one in the second pic looks to me like Padina sp., aka scroll algea. Usually not considered a nuisance.
