Rough White Buildup around my fish tank? Answered
I had a beta fish for a couple of months, and every time I did a water change, rough white residue was on the lid and around it on my desk.
Sadly he has passed away and the white rough residue is on my wall and every time i try to clean it, it comes back.
If anyone knows how to clean it properly or if you can tell what it is and how it happened as well as preventing it. Please comment.
