About This

• 🐟【Rapid Heating & Dual-Temp Control】75W aquarium heater is ideal for 5–20 gallon tanks. Made with stable nickel-chromium heating wire and silicon carbide heat conduction, it heats water quickly and maintains consistent temperatures. Built-in dual-mode thermostat supports °F/°C display (68–93°F / 20–34°C). Press and hold the button for 2–3 seconds to switch units easily.
• 🐟【Smart Dry-Run & Overheat Protection】Aquarium heater is equipped with an intelligent temperature sensor system that automatically shuts down if it detects the water temperature rising above the set limit, preventing overheating and ensuring the safety of your aquatic environment. The indicator light will turn green when the heater is operating normally, providing you peace of mind.
• 🐟【Explosion-Proof Quartz Glass Design】Constructed with thickened explosion-proof quartz glass and high-temperature resistant materials, this heater resists cracking and corrosion. The reinforced black ABS shell provides excellent insulation, protecting your hands and fish from burns.
• 🐟【External Digital Controller with LED Display】Features a clear 2-digit red LED display that shows real-time water temperature. The external controller allows you to set and monitor temperature without getting your hands wet—just press to adjust, hold to switch between °F and °C.
• 🐟【Easy Installation & Wide Compatibility】Designed for small aquariums, betta tanks, shrimp tanks, and turtle enclosures. Strong suction cups securely attach the heater to tank walls—vertical for fish tanks, horizontal for shallow turtle setups. Keep fully submerged for best performance.
