Mold on canopy (saltwater tank)
So, I've been on vacation for the past two weeks. My roomie has been feeding the fish, etc. When I came back, the fish were happy... all the parameters were good. I was so relieved.
Then... as I was pulling down the top of the canopy I noticed white/green "puffy" or fuzzy mold. I won't blame anything on my roomie, as I don't think he did anything wrong.
But, I really don't know how to treat it or what I should do next. I've been keeping an eye on it, and it's definitely spreading.
To also clarify, I did remove the glass top. But, I don't feel any over spray... and the area that it's in doesn't have much surface agitation.
What are my options here? Any help would be so much appreciated!
