I didn't realize how much electricity it might cost to keep a 100 gal warm...is there a way to maybe keep it more insulated? trying to cut down the electric bill.
p.s. i'm not taping sterofoam to the sides of my tank.
--You can raise the temperature of your room, transfering heating costs to a furnace using cheaper oil/gas.
You can get rigid sheets of insulation at any home improvement store. A sheet underneath the tank will help some (although you'd have to drain the tank to lift it and slide it under). You can also put some on the sides of the tank between the glass and the wall. If it's a real tight fit I've also seen some semi-flexible rolls of the insulation that could slide in there. Just cut it to fit and you're good. Every little bit will help, and you probably won't be able to see it once it's all in.
