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. 🌻【200W Fits 20-40 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.
