Size

Suction cups

If the temperature you set is ten degrees higher than the room temperature, choose a larger size

Example: I have the 4Gal aquarium, I buy the 25W heater.

But, it's cold, the air temperature is 46°F degrees, I want to heat the water up to 68°F, I have to buy 50W which is more power because the air temperature is more 15°F than the water temperature

  • < 8 Gal of water choose 25W
  • <13 Gal of water choose 25W
  • < 26 Gal of water choose 25W
  • < 52 Gal of water choose 25W
  • < 80 Gal of water choose 25W

Perfect for your fish and turtle, creating a stable environment in the aquarium

Remark:

(1) You need to put this product completely in water for operation.

(2) The heater heats up more precisely in the circulating water, the best position is at the outlet of the water.

  • Save electricity: turn off and on automatically depends on temperature
  • Indicator on thermocontrol
  • Sets temperature automatically after reconnection
  • Protection of over-temperature
  • Small size, leaves more room for your fish and plants

Tips: Some users use their hands to measure the heating temperature, believe that the water is not hot, and think that the product does not work, which is inaccurate, because the human body temperature is 36 degrees Celsius, and our heating temperature is lower than the human body temperature, so the water will be cold. If your hands are also cold, below the heating temperature, you can feel that the water is hot

Heater works very good stoppers that came with the heater is not worth two cents. They do not hold the heater to the glass.

Not much to say other than it's an aquarium heater that maintains a constant temp in my aquarium. Using it for my 6gal betta tank.
