  • 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.

How to choose the right heater for your aquarium?

There are 3 elements to consider to determine the right heater for your aquarium size:

  • Room Temperature
  • Aquarium Water Volume
  • Desired Temperature

Experts recommend 2.5 to 5 watts per gallon (WPG). For example, a 10-gallon tank needs a 25 to 50-watt heater. Adjust based on room temperature, colder rooms may require more than 5 WPG.

I have a little 3 gallon tank that is difficult to keep clean. I love this little filter! It’s easy to pull out and clean the sponge every couple months. The water stays clear and aerated from this pump.

Stops working if water gets too low which is a good thing unless you don't keep the water level to the right pointlike I did, then your fish gets cold

Though it looks a little bulky in my three gallon, it keeps my three neocaridina shrimp at a more appropriate temperature than they would be otherwise. The heater seems to fluctuate up and down about two degrees from what it's set at, which hasn't bothered any thing living in the tank from what I can tell.

First things first, dont depend on the temperature that the heater is set on to be your thermometer! I found that if you bought the heater that is the correct wattage for your size tank, the digital reading on the heater will actually be around 1 or 2 degrees lower than the actual temperature of the aquarium. This is a good sign that you have the correct wattage. So in short, be sure to have a separate themometer on your tank. I love the compact size most of all!

This Fish Tank Heater is very compact and works great for a small size aquarium. It’s easy to setup and It regulates the temperature pretty effectively. The temperature display is always on making it easy to monitor and it’s only a degree off from the tank temperature gauge that I have. There is a poorly placed sticker on the actual heater element so I do suggest peeling it off. The rubber bottom piece on the end of the Element always slides off, definitely needs a sturdier end piece.
