Tips for Using Aquarium Heaters:

1. To get an even and thorough heat distribution in the tank, it is recommended to place the heater to an area with good water circulation.
2. The aquarium temp will fluctuate depending of the room's ambient temp so it is normal that it has differences within ± 3°F, and if the room temp is below 60°F, you need to choose a more powerful heater than recommended in the list.
3. To avoid injury, do not touch the heating part directly.
