I do like that it is flat, but I don't want to spend 15 dollars on a heater I wont use if it gets too hot.
I might have to find something else to work.
I don't think you need a heater at all if the water stays close to that.
Generally water will run a couple degrees under the air temp, you can bring this up by putting plastic over most the top to reduce evap.
If the 2 gallon has a power filter or air pump operated filter those will keep it warm just fine. (in the winter I put my air pump on top of my "space heater" thousand watt computer, it pulls in warm air that it pumps into the tanks)
My 2gal petco hex stay at 78 degrees in 72 degree house if I run the lights about 10 hours a day.
