Brown Stains in Tank #1
Hi all,

First time posting here and looking for help.

I recently (2 weeks ago) bought 3 goldfish for my kids and there seems to be some form of brown discolouration or staining on the stones and the filter of the tank. Please see attached picture of stones.

Any thoughts on what this might be and how to resolve?

Thanks in advance.
