I found a 20 gallon tank with a whisper 30-60 filter in my storage building. I forgot it was out there but figured it would make a good QT tank for my 90 gallon. Problem is that it is pretty dirty. What is the best way to clean it? I do not need it now bit may in a couple months. Someone said I could bleach it but would that not hurt the fish in the future?
