Hello,
Could anybody help me identify what the rust-colored spots on my substrate and rock is? I've tried to stir it up to get rid of it, but it comes right back within a few hours. It is getting worse, too. I suspect it is some sort of algae, but I'm not sure. I am new to this hobby and any help on identifying and suggestions on how to get rid of this will be greatly appreciated!
