I noticed last week that when you walk into my room it smells like something died. You go up to my tank and it's the tank that smells like that.
I cleaned his whole tank yesterday, scrubbed it down good and put some vinegar in the water I was scrubbing with, dumped that, and put totally fresh water in the tank when I was ready to fill it back up. I walk into my room today and that smell is back and it's coming from the tank.
What can I do to stop that and what is it?
