Even in Canada you can get a CO2 system for well under $300. And it would be money better spent than substrate heating cables. For a CO2 system you need the following; cylinder, regulator, needle valve, bubble counter, reactor. And you can build the last two yourself. Read my Guide for ideas on where to find the rest.
BTW, how much light are you going to have on this tank?
