🐠 Aqueon Submersible Aquarium Heater: Efficient and Reliable Heating Solution for Your Fish Tank Review

Works reasonably well in a 10 gallon tank. It may seem to run a few degrees warmer than you set, but that doesn't matter, just turn it down. Be sure to follow the instructions and submerge it to the minimum waterline and let it sit for half an hour before turning it on. Has been working without problems for over a week.

Useless! Hundred Dollar Fish killed. Twice! Set it to 78 and it will last a full three weeks. Then, in fourth, he jumped to 94 despite not touching anything! Two different Bettas both died from overheating. If Revane hasn't realized that this is a weird form of Russian roulette for killing fish, they shouldn't be selling it at all!

It's been in my 10 gallon tank for 5 days and the red light never goes out I have 2 thermometers in my tank reading 75° wow the heater is set to 83°, it might be a bit cold in my room because it's always at 71, so I'm pretty sure I have the right size heater, maybe I just got 41, I'll be back when something better happens

Fantastic heater for my 10G. I had to raise the temp to 86F to cure the slight itch and it worked great. Our house stays at 76F and has had no problem maintaining a consistent temperature. It's spot on and doesn't wobble. The price here is about 40% lower than in large pet stores. I also have a 100w Aqueon heater that works just as well. This is a great purchase!

This product keeps the water temperature at 80 degrees all the time which is what I wanted. I use this in my Aqueon Evolve 4 tank and haven't had any problems. I bought this instead of a cheaper 10 watt heater based on negative reviews. This product also has an indicator light that lets you know when the heater is on and the water is heating. This heater doesn't stay on all the time, instead using what I think is the thermostat when needed.

Not installed and forgotten! The product has a reasonable price. I think the biggest downside is the temperature marking on this device. There are none other than the tags shown in my photo. Tagging makes the fish a guessing game (life or death). If the knob is to be moved to a temperature between 76 and 80, you have to guess where the 78 degree mark is. It's a trial and error method of temperature control with a separate thermometer! I will work with this device until I reach the desired…
