Here's an idea for a DIY project I've been kicking around but haven't tried:
Hardware stores sell "Heat Tape." It's a flexible wire with adhesive tape that you wrap around outside water pipes and plug in to keep the pipes from freezing in the winter. Why couldn't you put this tape on the bottom outside of the glass and do basically the same thing as heating cables in the substrate for a tiny fraction of the cost? You would be warming the glass, which should warm the water at the bottom of the aquarium.
The unanswered questions I have are:
How hot do the cables get?
How far apart under the glass would you put them?
Do they put off enough heat to need a thermostat?
If they need to be thermostatically controlled, I've seen 110Volt thermostats that are designed to control something like a space heater in your garage but I don't know if the thermocouple would be sensitive enough.
Just something to think about.
