Any suggestions as to what heater I should be using in a new 29 gal
setup? I've got an old heater that does the job but is very finicky. It is the kind with the dial on top where turning clockwise turns up the heat and counterclockwise turns it down. It is definitely working; but does seems to have a pretty large temperature window of where it shuts on or off. I've got it to a point where it keeps the tank between approximately 70-78 degrees but I feel like it should be a little more accurate. I also notice that vibrations will turn the heater on. For example, a heavy footstep near the tank will cause the light to turn on. Similarly, if you just tap the heater it will turn on. If you leave some pressure on the heater it stays on but turns off as soon as you remove your finger.
Am I just being too critical of this thing or should I replace it with something better?
