About this product
Inside the box sit a mini aquarium heater with its power cable attached, a sticker thermometer, two suction cups and a bottom cover. The 25W model is rated for 2-6 gallon tanks, and the heater itself is 3.7 in long. It can be set from 64-93°F, and the temperature is adjusted on the external regulator rather than in the water.
The heater's main features and what they do
The external temperature regulator is separate from the heater, so you set the temperature without putting your hands in the tank. The range runs from 64-93°F. After a power failure, the power-off temperature memory function brings back the setting that was in use before.
The heater is made of thickened quartz glass, and the 1.5 m power cable gives some length between the tank and the outlet. The manufacturer describes the low power consumption as a way of helping prevent overheating.
What comes in the pack
- A mini heater with the power cable connected
- A sticker thermometer
- Two suction cups for mounting the heater on the inner wall of the tank
- One bottom cover, which protects the heater and keeps it from touching the tank bottom directly
Checks to make before you buy
In the same range, the 15W model covers 1-4 gallon fish tanks and the 35W model covers 4-10 gallon nano tanks, betta tanks, fish bowls and desktop aquariums.
The manufacturer lists fresh water and saltwater tanks, betta tanks and turtle tanks as suitable. Check that the heater's length of 3.7 in fits the space on the inner wall where you plan to attach it with the suction cups, and that the 1.5 m cable reaches your outlet.
