I am setting up a used 29G cube for a seahorse tank. The back wall is covered with old dried up coralline. I could clean it with no problem but my question is. Is it necessary? Will it hurt if I just left it in there? I would prefer the look of the coralline to a blank back wall anyway.

No need to clean it but it will turn white from dying if it hasnt already.
