Currently setting up frag system in the basement, and always considered insulating the tanks (rubbermaid stocks) to save on heating costs. Even though most of the heat is probably lost from the surface, I'm sure insulating the sides could make some difference. Was also considering air-lifts for main flow in frag tank, but the "new" propeller powerheads are quite efficient.
As for greenhouse, I read that you can use large black barrels/containers of water to help hold the heat. Sun heats it up during the day, and the heat built up helps keeps temps up during the night.
