Purple stuff?

[tomtown]

I have a 14g biocube thats been up and running for about 3mo.The tanks starting to grow some kind of purple stuff on my L.R.andL.S.Everything in the tank is doing great,I was just wondering what the purple stuff is?Is it good or bad?Do I need to try and get rid of it and how?

its called coraline aglae and is a good thing it keeps the bad algaes from attaching and gives the tank a nice coloration
