That homeade heater looks like a good way to go. Do the elements come with all the wiring or do you have to wire it yourself? Will this application with lead piping be good for use with fish? Dr. Joe, wish I could go awol. lol. Sure it would look really good on an MP in the military to go awol. lol. Oh well. Can't wait til next time I have to move. A 2000 mile road trip with the fishes. Look for me here again then lol.
