I have this red lettuce looking stuff in my tank, it started growing about 6 months ago and next thing I know it got huge, anyhow it looks pretty cool and it's pretty under control but I was just wondering what it was.

Can you get a closer picture? At first I wanted to say Padina, but I've never seen it that shade before.

Yeah it's definatly not Padina, I'll try to get a closer pic, but I'm having problems with my camera.
