Características

• 【Choosing the right heater size?】This 500W aquarium heater is precisely designed for 55-80 gallon tanks — ideal for 55, 65, and 75 gallon freshwater or saltwater aquariums. Comes with a detachable protective shield and 2 strong suction cups. Easy to install and hide in acrylic or glass tanks. (110-120V, 5ft cord)
• 【Need precise temperature for different fish?】Rotate the dial to choose from 8 preset temperature settings: 68, 71, 75, 78, 82, 86, 90, or 94℉. That means you can easily maintain a stable aquatic climate within just ±2℉ of your target — no guesswork, no complicated programming. Perfect for tropical fish like angelfish, discus, or guppies that need specific warmth.
• 【Worried about temperature swings harming your fish?】The smart auto-thermostat constantly monitors water temperature. It stops heating when the water reaches 1.5-2℉ above your setting, and automatically restarts when it drops 1.5-2℉ below. No manual adjustments throughout the day — your fish enjoy a stable, healthy environment while you relax.
• 【Afraid of heater cracking or shocking your fish?】This heater is built with shatter-proof quartz glass and a double-sealed casing — blast-proof and leak-proof. Even if accidentally bumped during cleaning, no risk of cracking, scalding your fish, or electric leakage. Safe for both freshwater and saltwater aquariums. Premium peace of mind for you and your aquatic pets.
• 【How to know the real water temp without guessing?】Unlike most heaters that only show the set temp, this kit includes a separate LCD digital thermometer. Place it anywhere in the tank to get the actual water temperature at a glance. No more overheating or freezing due to heater miscalibration. Dual-device accuracy = healthier, more active fish.
