"5 gallons."

Once attached to the tank wall I've had no issues with it coming off. For Discus you need warm and accurate heater and this seems to do the trick. It comes with a hanging kit and can be secured on the edge of the tank. And I get to keep the first one I bought! I recieved this product without the instructions or the added thermometer. Keeps the water consistent and it's easy to adjust! The setting always stayed the same.

Tetra 26445 Final Thoughts

"It easy to set."

Seems to keep the temp n the tank fairly regular. Maintains it well except when the weather is already warm then it over heats it. Also I like how it shows both the current temperature and the set temperature. I contacted the manufacturer and they sent me a new unit in less than a week! The temperatures are pretty accurate. Am a totally sold customer and would recommend them to anybody! I think it works well to not stand out like other heaters.

No biggie, but annoying nonetheless. My heater is fully submerged underwater and works perfectly fine. The controller is easy to use, very accurate and reliable. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. Easy enough to let it run all the time. I waited a little bit to write the review so it could be accurate.

"I like the size."

Once I opened the box i noticed the quality of the construction. The red light means it's off, blue light means the temperature is constant. My fish likes to get close to it and he has never been hurt by it. My fish likes to get close to it and he has never been hurt by it. They shipped us the upgraded version that also heats!

"I'll try once more."

The heater is easy; turn the dial to set temp and plug in. We wish the controls were available in Farenheit also to make things a little easier. I was worried about the quality but I am thoroughly impressed with this heater! I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. When i installed them, i let them sit in the tanks without power for 6-24 hours. This is a great heater that is very easy to set up and program. Would be great to be able to tune that to.
