That's what my ceramic and glass diffuser jammed in the filter outlet looked like, small bubbles but no mist. You know a mist when you see it, if that tank was properly misting, not bubbling then those fish would be dead within an hour. I'd know, I've gassed many a fish in my time :fshi:
Just out of curiosity Finznfangs, what are the specs of your tank? Any photos I may have missed?
