  • Working great!
Size: 100W
I have a small five gallon tank I'm using for aquatic invertebrates. While room temperature is okay, the heater brings it up to 80 degrees F and that's perfect for my guys. I had a thermometer on the outside of the tank that was measuring my temperature before, and it matches with the temperature shown on the heater, so it seems to be accurate. I haven't had any issues with it overheating or my bugs going into it. The suction is okay, I had to reattach it once but that might just be a skill issue. All in all, I'm really happy with this! ... show more

  • Keeps temp at 78
Size: 150W
I have this in a 10 gallon shrimp tank. It keeps the temp to around 78, which works well for my colony. The LED display doesn't seem to be all that accurate, but I keep a second thermometer in my tank away from the heater as a backup. It reads consistent temps, even as the temperature of my house cycles. I find the LED reader a little distracing from my planted tank setup, but the light wasn't so bright that I wasn't able to cover it with some hardscape and plants. ... show more

  • Simple heater
Size: 150W
This heater is a simple heater and you cannot adjust the temperature on it. Just plug it in and put it in the tank and it will keep the temperature at a consistent 78 degrees. I used this for a 30 gallon and it seems to work well. The thermostat showed a temperature of 78 at all times. It seems to do what it says to do. ... show more

  • Very nice little heater
Size: 100W
I stuck this in my 10 gallon tank with my betta fish that needs the water to be between 78-80F and this heater kept the water at 79 degrees steady which is perfect! Update: Sadly i have to change my initial positive review as for some reason the temperature Guage on this heater kept fluctuating several degrees within a single minute. This made me feel unsure of what the actual temperature of the tank was or if the heater of thermometer was at fault so I had to change it out for a different heater and thermometer. I'm disappointed as I initially really liked this heater. ... show more

  • It's Easy
Size: 150W
Dropped this heater in a 40 breeder that I am setting up for some Neolamprologus Lelupi. Even though the tank is a little larger than the recommended maximum size, this heater is handling the job. The temperature of this heater is preset at 78F, and the water in my tank varies from 77.5F to 88.7f as read with an external thermometer. The reading on t he heater is within a few tenths of the external. This type of heater is easy. Most tropical fish will thrive at 78F so it works in many tanks. An added bonus on this unit is the temperature readout, which most preset heaters do not have. I can't tell how long this heater will last, but so far so good. I suspect the fact that it does not have an adjustment mechanism makes it a simpler device and that should help it last. ... show more

  • Precise and Powerful
Size: 150W
The Yaubay 150W Aquarium Heater has been a reliable addition to my 20-gallon tall aquarium, maintaining water temperatures exactly where they need to be. Although it's a bit more challenging to conceal due to its size, the heat output and consistency make up for it. Overall, I'm very pleased with its performance and would recommend it for anyone needing a stable heating solution for similar-sized tanks. ... show more
