Corraline on glass

[Devan Patel]

Hi, any suggestions on how to get this corraline off the glass? I’ve used multiple metal scrapers but it’s really stuck on there and I don’t like seeing it in

the front.

I feel your struggle!
I use a combination of a plastic putty knife and my fingernail. The putty knife gets it going, reducing it, and my fingernail takes off the rest. It’s still not easy and takes many passes. I’m tempted to get a tuxedo urchin, but in my smallish style tank, I worry that it’ll knock over corals.

I only want coralline on my rocks, not on the glass nor the back acrylic wall. Every week, during maintenance day, I remove some.

Use a razor blade.
I use this and it works well.
