Tested with a Thermometer — Runs About 2° High
I spent hours researching before choosing a heater for my 5-gallon tank with baby GloFish, and this is the one I ended up going with. So far, I’m really happy with it.One of the biggest reasons I chose this model is the adjustable temperature. It has a wide range (59°F–93°F), which gives much more control compared to preset heaters. That’s especially important in smaller tanks where temperature can fluctuate more quickly.The digital display is a huge plus, but I still tested it with a separate thermometer to check accuracy. I found that it runs about 2°F higher than the set temperature (for example, set to 70°F → reads about 72°F on a separate thermometer). Once I adjusted for that difference, it held temperature consistently.Installation took seconds — it secures easily with suction cups and stays in place without shifting. It’s also a good size for a 5-gallon tank and doesn’t feel bulky or intrusive.The controls are simple as well. You just press the button to cycle through temperatures, and you can hold it for 3 seconds to switch between Fahrenheit and Celsius.One thing I really appreciate is that it has built-in safety indicators on the display:E1 = heater shuts off if it’s out of the waterHH = temperature is too high (over 95°F)Both are helpful safeguards and easy to correct — just fully submerge the heater or allow the temperature to come back down.It’s also recommended to keep the heater from directly touching the bottom of the tank, which is something to keep in mind during setup.Overall, this has been a solid, easy-to-use heater that gives me more control and peace of mind. Just be aware of the slight temperature offset and adjust accordingly.I will update if anything changes with longer use!⏩️Fast forward:It has been 2 weeks of constant use (24/7) and I have had great results. The thermometer has kept my tank at a consistent temperature without any unwanted fluctuations. It still runs about 2° higher, but has not showed any signs of going higher or lower than that.⭐️I included a setup video as well as photos + comparison temperature readingsVer másVer menos
