Stuff on my LR?

[urbanhellfire]

Iam going with a LR and a fish or two set-up. My LR and LS have been in the tank for Six weeks this friday. Iam starting to see some yummy green film algae on the rock so iam going to start adding a few snails, but I also have some very dark Black or very very dark Purple growth on the rock. Is this the norm?

Thanks everybody!

Absolutely

I was not sure as all the rest of the rock has the normal purple,deep red and nice lime green coralline, the blackish color just threw me, anything blackish in my FW tanks scares me.

Thanks again, best site on the web for info I have found yet!
