Is there such a thing as grass algae?

[asylumdown]

thanks, I will look in to a sea hair and cut back an hours worth of lights. I had one back when I first set up the tank and the brown slime algae went out of control, but I had accidentally thrown out the mesh socks for my vortech mp10's (they looked just like the used filter sponge I was getting rid of) and it ended getting turned in to soup after a week. I made a new pair of socks for the vortechs last week when I discovered a really beautiful sea slug that had hitchhiked in to my tank (Sponge eating from what research I've done on it).

I'll take some pics when I get home tonight and post. I just checked back at some photos I took a month ago and that rock wasn't nearly as overgrown. I hadn't realized how fast it had gone!
