Coralline driving me crazy!

I don't care if the urchins spread it, as long as they can eat it faster than it spreads. Is this possible?

I would think passing the algae through a digestive system (the urchin's) would kill or denature the algae... That being said, I'm sure that an urchin (depending on the size of the tank) can eat coralline pretty fast. I'm sure you'd have bare spots on your rock... but as far as the coralline on the glass, I think you may be stuck. I've never heard of a snail eating coralline. Or an urchin climbing glass...

I have two urchin and they do climb the glass they can also move fast if they want

my suggestion, is go to the hardware store, buy some razors, and start scraping (unless the tank is acrylic)

its a tedious and boring task, but its worth it IMO. also an urchin wouldn't hurt.

marie, i dont think you'll ever have a coraline free tank

I stand corrected I suppose that since they have tube feet, this wouldn't be a difficult task.
