but is there supposed to be a stench to water in a tank.. its not a bad stench but my room dpes smell like fish.. and the water in the tank is crystal clear
My tanks have a smell to them.... but like Must4ng s4lly describes it... its an earthy smell. I can only smell the water when I am very close to the tank... generally when I'm doing a water change. I actually enjoy the smell . I suppose if enough volume of tank water is put together in one place, it can produce a powerful enough smell.
I only smell the water when I raise the tops. Like Richer, it's not an unpleasent smell. IMO, smelly tanks are a good indication of overfeeding, or other water quality issues.
