Thank you Li'l Ole Fish Lady...
There were no strange noises... It just quit. I have all of the powered equipment on one power strip. Everything else is fine...no problem with power. I didn't take out enough water to go below the suction line or anything else that I think would cause the motor to burn out. Its a bit of a mystery to me.
I am in Laramie, Wyoming, so there are no local fish stores. I have to go to Fort Collins, Colorado...about an hour and half away (when the roads aren't closed for winter storms!) for an LFS. So, since I can't do that tonight, I went to Walmart. I hate supporting their fish department, because I think the way the treat their fish is deplorable and the advice I have heard them give people is worse. But, I got a filter that I am sure will get me through for the time being. I just pulled out their chemical filtration bag and replaced it with my bag of ceramic ring media which I kept in aquarium water throughout the last 1.5 hours.
I like your idea of trying to repair my old filter. Even if I don't decide to start another tank, I can have it on hand as a back up, should anything like this happen again!
Thanks again!
