The double-sealed design ensures zero water leakage or electric shock risk. Perfect for both freshwater and saltwater aquariums where corrosion is a concern. - 【Keeping tropical fish, cold-water fish, or even turtles?】 The adjustable temperature range covers 68-94℉ (20-34℃) — warm enough for discus and angelfish, cool enough for goldfish, and suitable for amphibious turtles that need basking warmth. One heater works across freshwater, saltwater, and reptile setups. No need to buy different heaters for different pets. - 【Tired of reaching into cold water to adjust your heater?】The external controller lets you change temperature settings without getting your hands wet or disturbing your fish. Just press the button — each press increases 2℉. The bright LED digital display shows real-time water temperature at a glance. No more guessing, no more wet arms, no more stressing your fish. - 【Concerned about sudden temperature changes affecting your fish?】 The smart auto-thermostat continuously monitors water temperature and adjusts heating power automatically — not just simple on/off switching. When temperature drops, it adds gentle warmth. When it rises, it reduces power. This helps avoid sudden spikes or drops, supporting a stable and healthy environment for your fish. - 【What does the heater do when water level is low?】 This heater includes a built-in sensor that monitors water level. If water level drops below the safe range, the LED display will show an error code to alert you. Normal operation: heating stops when water reaches set temp, restarts when temp drops just 1℉ below setting. The indicator light glows red while heating. ## Technical Specifications | Specification | Value | |---------------|-------| | Customer Reviews | 3.9 out of 5 stars 549 Reviews | ## Images ![Digital Aquarium Heater - Image 1](https://m.media-amazon.com/images/I/6130-lbbBCL.jpg) ## Available Options This product comes in different **Size** options. ## Questions & Answers **Q: Is this ul or etl (etc) certified?** A: No. **Q: will this heater work for 150 gallan aquarium?** A: From my experience, I would say yes, if you had one at each end of the tank, and good flow. **Q: is it safe for acrylic aquariums?** A: Yes **Q: I Installed as per directions in tank Getting error code.
