coraline algae on back glass

#1
Is there a trick to keep the back glass clean? I just use a razor blade but that a ton of work and i often brak corals.....

Kind of a dumb qustion but i am curious if anyone has gcome up with a better way.

Thanks

yeh let that stuff grow then put encrusting corals on it. I think it looks really neat. The coraline algea makes a good base for corals to grow on!!!
