Recommending a size for a heater is difficult because there are so many factors that go into correct sizing. These include room temperature, material the aquarium is made out of, how high the temperature is set, if other equipment like filters are running (which add heat), and finally if the aquarium has a tight fitting lid. In our experience, our 100 watt heater can heat up to a 75-gallon tank in a home with a proper fitting lid at 78°F. However, add a second heater or reduce tank size for non optimal conditions.
The heating unit itself is fully submersible. Do not submerge the temperature control mechanism.
If the suction cups do not stay attached, please make sure to clean the aquarium wall before attaching the heater. We recommend using an algae scrubber or other appropriate tool for wiping off any algae or debris to ensure that the surface is completely clear and flat.
