    Placed it in the water horizontally (completely submersed), works perfect. Has a little red light that shows when it is running which is somewhat hard to see in this mounting position, but all in all a good heater, no fuss.

    This fishtank heater works great. I’m using it in a 29 gallon tank. I set it to 79 degrees and my temperature strip on the tank shows 78 degreees. I’d say it’s accurate. I recommend buying it.

    Accurate and consistent, December 13, 2009

    This heater is accurate and consistent. If you are looking for a heater then it is more important that it keeps constant, consistent temperature. Being accurate is not important as long as you have an accurate thermometer.

    If you are heating your tank for the first time then it is easy to get to the temperature that you want.

    1) Put the heater in the tank and set it 10-15 degrees higher than your temperature goal
    2) Watch your thermometer – either the floating or stick on
    3) Once your temperature goal is met, lower the setting on your heater and immediately stop when the red light goes off
