About This

  • COMPACT SIZE - This aquarium heater is incredibly short in length, possibly the shortest on the market. It's just over half the length of traditional fish heaters! This innovative, ultra-compact design is a perfect fix for the long-standing issue aquarium keepers have had with conventional heaters. It's compact and inconspicuous, but doesn't compromise on power! It offers a temperature range between 64F and 93F.
  • PRECISE TEMPERATURE CONTROL - Courtesy of cutting-edge inverter technology and integrated chips, this fish tank heater ensures stable temperature control with an impressive accuracy of 1F. That's a huge leap from old-school, knob-controlled heaters. With its user-friendly thermostat displaying current and desired temperatures, operating this heater is a breeze.
  • SAFETY FIRST - Overheating and dry run protection got you covered. If the water dips below the minimum required level, the heater switches off (DRY RUN PROTECTION). It also powers down if the water temperature surpasses 97F (OVERHEATING PROTECTION), so you don't have to worry about inadvertently "cooking fish"!
  • MEMORY FUNCTION - Last settings are stored in the thermostat's chip. In case of power loss, the aquarium heater resumes operation based on the last recorded setting upon power restoration.
  • VERSATILE APPLICATIONS - This heater isn't solely designed for aquariums. It's perfectly compatible with both fresh and saltwater environments. Beyond functioning as a standard fish tank heater, it can double up as a turtle heater, pet fountain heater, or a plant seedling heater.
