Precise Temperature Control: This intelligent mini heater maintains optimal tank temp at 78.8 °F with ±3.6 °F accuracy. Smart PTC technology automatically triggers heating when water drops below 77 °F and safely shuts off at 93.2 °F to prevent overheating
Enhanced Security: Double-layer waterproof sealing with a reinforced shell makes this betta heater ultra-safe compared to fragile glass heaters. The innovative split-chamber design separates heating and control components, promoting even heat distribution
Compact Size: Measuring only 2″ L x 0.5″ W x 2.6″ H, this space-saving submersible aquarium heater works perfectly in water as shallow as 0.8 inches when positioned horizontally. Its minimal footprint maximizes swimming space for your fish
Easy Installation: The 3 strong suction cups and generous 5.3-foot cord allow flexible placement of this heater for fish tanks. Simply attach it to your tank wall or bottom and plug in. (NOTE: Keep the heater fully submerged during operation!)
Wide Application: This submersible fish tank heater is ideal for 1.5 – 3 gallon freshwater and saltwater aquariums – betta bowls, turtle tanks, paludariums, and more. Maintain consistent comfort for all your aquatic pets year-round
