The FREESEA aquarium heater is one of the most loved portable heaters by fish lovers. The heater features a generous temperature range of 54 degrees to 94 degrees, which will accommodate various types of fish, turtles, and sea plants. The 50 watts version of the heater is suitable for aquariums with a capacity of up to 10 gallons. The compact design of this heater ensures that it only takes minimum space from your aquarium while providing the fish or other water life with a comfortable-to-live-in environment.
The heater features an automatic constant temperature feature where you can set a non-varying temperature for your aquarium. With this feature, the heater will automatically turn on/off as the water temperature changes, thus keeping constant. The FREESEA aquarium heater is fitted with a touch button that is safe and easy to use for the temperature adjustment. However, the temperature control system could have been better with a knob rather than a cycle-through button. Regardless of the foregoing, the device works perfectly well in both fresh and salty water.
The heater is fully submersible and should always be under water when turned on. This is important to maintain its useful life and prevent dry heating. Even under water, the superior quality LED temperature display panel remains readable, giving you a correct temperature at a glance. Besides, the heater uses a built-in thermometer eliminating the need to buy a freestanding thermometer. The heater connects to a wall outlet using a 3.5 foot long cord, which is still convenient and safe to use even though it is shorter than that of competing products.
