I was trying to save money on a bait tank. Neighbor gave me a new trash can and I had a 1/2 horsepower sump pump in the basement I wasn't using.I figured I could make my own filter from material from a pet store.I spent $1.40 at Home depot on a female to male pvc connecter an elbow connector and a cap. I drilled holes on both sides of the sprayer pipe and rigged it up and plugged it in.Water sprayed in every direction , even up over the garage roof. I then realized I should have only drilled holes in the bottom of the pipe so the water would spray back into the tank not in every direction.I also realized that there was more current in the tank than below Truman dam when the gates are wide open.Since I being the genius I am had already glued the pipes together I had to run back to home depot and buy more pvc connectors and start over.I put it back together and rigged it back up.That night I went out to the same lake I had been catching bluegill at and had terrible luck. I only caught 3 bluegill in spite of moving all over the lake. So I brought them home and put them in my new tank. The next night when I came back to check on them I could see steam escaping from the tank as I walked up to it and it smelled like fish chowder.As I uncovered the tank escaping steam burned my hand. It smelled like cooked fish and the water was boiling slightly. Needless to say the bluegills were cooked into submission.You gotta be able to laugh at yourself.When I read the instructions on the sump it said danger not for continous use may overheat. Lucky I had it on a power strip and didn't burn my house down. Do not try this at home folks.
