Where can I buy one?

I bought a 300W cable heater at M3 for $60. I connected it to a regular $5 light dimmer, which lets me control the heat output in a continuous fashion. Also, I have it on a timer, so it kicks in only at night, when the lights don't heat the water. I didn't use it much yet, but Winter is coming.

It's a great idea... gentle nutritious currents, warm feet, and very efficient heat distribution, but I don't think there is hard proof that it actually improves plant growth, much less that it is required to have a planted tank.
I will not use mine for about 8 months of the year because I don't need a heater during that time... If I had to start over, would I use it again? I don't think so, for the very reason that Rex stated.

On the other hand, if you are using a heater a lot of the time, or have to keep a warm tank, like for discus, bottom heat is something plant nurseries will use to get a jump on growth in the spring.

Will this be for a tank in Oregon or in Alaska?
