HANLESHUKA 300W Submersible Fish Tank Heater for 40-70 Gallon

HANLESHUKA 300W Submersible Fish Tank Heater for 40-70 Gallon with Auto Shut-Off When Leaving Water—Aquarium Heater, Dry-Burn & Overheat Protection, Smart LED Display for Freshwater Saltwater Turtle
- 🐬【Heater Out of Water? Shuts Off and Alarms You Instantly】 Water changes, evaporation, or a curious turtle can push your submersible heater above the waterline — and most heaters just keep burning until the glass cracks. This water heater for fish tanks detects the moment it leaves water and cuts power immediately with an audible alarm. Re-submerge it and heating restarts automatically. Whether you have betta fish, a small tank, or a large setup — this feature prevents disasters.
- 🐬【3-in-1 Safety: Dry-Burn + Overheat Protection + Max Temp Limit】 Your fish get three independent layers of protection: (1) Dry-burn prevention — auto shutoff out of water, auto restart when re-submerged, (2) Overheat protection — stops at +1°F above set temperature, (3) Max temperature auto stop — will not exceed maximum settable range even if the thermostat malfunctions. Every trigger sounds an alarm.
- 🐬【Red = Heating, Green = Ready — ±1°F Smart Control】 The external LED thermostat displays real-time water temp and your adjustable target simultaneously. Digits glow red while heating, turn green when set temperature is reached. Intelligent frequency conversion adjusts power continuously for ±1°F precision — far smoother than basic on/off heaters that swing 3-5°F, stressing shrimp and sensitive tropical fish.
- 🐬【Wave-Pattern Guard — Sleek Protection That Disappears in Your Tank】 The elegant wave-shaped ABS guard wraps around the explosion-proof 2mm quartz glass element, shielding fish and turtles from hot surfaces. Its streamlined flowing profile blends into your aquascape — tuck it behind plants or driftwood and it virtually disappears. Corrosion-resistant for long-term freshwater and saltwater use.
- 🐬【Pick Your Wattage — Works from 5 Gallon to 120 Gallon】 100W = 10-20 gal, 200W = 20-40 gal, 300W = 40-70 gal, 500W = 70-120 gal. This submersible aquarium heater also works for mini setups and 5 gallon betta bowls. Fully submersible, freshwater, saltwater, brackish. Mount with suction cups on glass or acrylic. Switch °F/°C in 2 seconds.
