I have a glade plug-in going, no casualties

Are you sure it's the tank that's causing the smell? I mean I could see how you would assume this.. but maybe it's something totally different from your tank.. just a thought so your not searching for a smell only from your tank.

No its definatly a "fishy" smell, as my wife puts it. There is nothing else that would cause it.

Have you searched around your entire tank for more "stinkier" spots? Just sniff around .. you might be able to pin point where or at least close to where it could be coming from??

If you can isolate the smell to your tank, from what I've read here and there, your tank has far too many nutrients and filtration should be beefed up. That's just the jist of what I remember reading, I suggest research before doing anything drastic.

Dude, Its the tank.

Run some carbon in your tank. That will help with the smell. As will Ozone.
