- 🐠【Leaves Water? Power Cuts Instantly — Auto Restarts When Submerged】 Most submersible aquarium heaters keep running when exposed to air during water changes or evaporation — causing meltdowns, cracked glass, or fires. This aquarium water heater has a built-in sensor that shuts off power the moment it leaves the water, with an audible alarm to alert you. When re-submerged, it auto-restarts at your previous setting. Your fish and turtles stay safe even when you’re not watching.
- 🐠【Triple Safety: Dry-Burn Prevention + Overheat Protection + Max Temp Stop】 Three independent layers protect your fish around the clock: (1) Dry-burn prevention shuts off heating when heater is out of water and restarts when re-submerged, (2) Overheat protection stops heating the instant water exceeds your set temperature by 1°F, (3) Max temperature limit automatically stops the heater at its highest settable temperature — even if the controller malfunctions. Every alarm is audible.
- 🐠【±1°F Precision — Red Means Heating, Green Means Ready】 The external digital thermostat controller shows real-time water temp and your adjustable target simultaneously. Digits glow red while heating, switch to green when reached — check your tank from across the room. Intelligent frequency conversion continuously adjusts power for smooth, stable temperature control, eliminating the 3-5°F swings that stress shrimp, axolotls, and sensitive fish.
- 🐠【Seashell Guard — Protects Fish, Maximizes Water Flow】 The unique seashell-pattern ABS guard wraps around the explosion-proof 2mm quartz glass element. Its contoured shape directs water flow evenly for efficient heat distribution while preventing fish and turtles from touching hot surfaces. Built for long-term freshwater and saltwater use without corrosion.
- 🐠【500W Fits 70-120 Gallon — 5-Minute Setup, Any Tank】 Choose your wattage: 100W for 10-20 gal, 200W for 20-40 gal, 300W for 40-70 gal, 500W for 70-120 gal. This heater for your fish tank works with betta fish tanks, tropical fish, and small fish tank setups. Fully submersible for freshwater, saltwater, and brackish. Install with suction cups, set temperature, done. Switch °F/°C in 2 seconds.
