What size heater do I need for my tank?

Heater Sizing Chart


The guide is based on a maximum of 11 degrees difference between your room temperature and the desired aquarium temperature.  

If you room is cooler than the 11 degrees we suggests going the a larger heater.

    This chart has no way to tie wattage to model, and your product page doesn't list the model's wattage. How on earth do you expect this to be useful?
