Is it possible to have a Coralline-free tank?

Coraline is soo much better to look at than white and green. If you all dont want your's. I will be glad to accept all the scrapings from your tanks. After all it does filter the water too. It is very ideal in its own way. If you want to really rid it away ozone the heck out of it. But you will rid all the tank life.
Give me coraline.
