How to scrape?

[TikiBird]

I have coralline algae growing in spots on the back wall of my BioCube and I'd like it to not be there. I have read you can scrape it off. Could anyone please advise me, what exactly do I use to scrape it that won't harm the background?

Never mind, I think I will leave it! Lol If it bugs me more, I might try using an old credit card...

Some varieties of sea urchins can eat coralline algae. There are also numerous algae scrappers with different attachments that can scrape it off with ease.

Thanks, @Blmain! I'll check it out! I was just worried about it scratching the plastic.

I have a little urchin that I love who eats all the coralline off my rocks, but not the back wall. Lol[emoji13]

Haha well hopefully he gets to the back soon! Some scrappers have plastic attachments. Good luck!

Just leave it. if you scrape it, the stuff will just grow back.
