I'm coming close to the end of my tank build and I need to figure out how I'm going to heat this thing. I don't want 3 or 4 heaters stuck to the wall inside the tank. I don't want to have to go to 220v. I don't want to spend a ton of money. I will be building a sump so most likely I will be heating from the sump. DIY is not an issue for me but I need ideas. Anyone out there that has done something creative please post some pics or explain to me their ideas. My online search has turned up pretty fruitless so I need to pick your collective brain.
