Product Details
✓DUAL DIGITAL DISPLAY CONTROLLER - Two LED screens show Set Temperature and Current Water Temperature at ±1°F / ±1°C. Use the +/− buttons for 1-degree steps instead of cycling the full range. Press and hold 3 seconds to switch °F and °C.
✓4-LAYER SAFETY WITH E01 BUZZER AND HH ALERT - If more than about 2 inches of the heater sits above water, the display flashes E01, a buzzer sounds, and heating stops. If water reaches 97°F (36°C), HH appears and heating pauses until it cools to 96°F. A thickened ABS cover helps keep fish from touching the tube. Settings return after a power outage.
✓FAST CERAMIC-GLASS HEATING FOR FRESHWATER AND SALTWATER - Ceramic glass tubes and nichrome wire heat the water evenly. Choose 25W–300W for tanks from 2 to 80 gallons; this 100W size fits 10–20 gallon betta and turtle tanks. Keep the heater fully underwater and at least 5 inches below the surface, then lock it with 2 suction cups.
✓DETACHABLE HOUSING FOR EASY CLEANING - Unplug and wait 15 minutes to cool, then remove 4 screws to open the shell. Wipe the sensor and heating tube with clean water to clear scale that can throw off readings. Reassemble firmly before use. Clean every 2 weeks for optimal performance and long service life.
✓PLUG AND HEAT IN MINUTES - Rotate each suction cup 90° to lock, then mount vertically or horizontally. The external touch controller keeps your hands dry. Temperature range 64-95°F (18-35°C) with 1-degree adjustment steps. Works with freshwater and saltwater setups.
