"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.

"I like it."

I love the heater otherwise, but I'm afraid some water has gotten inside the heater. I emailed the email it says to and told them. Would be great to be able to tune that to. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. It does blend well in some setups and may look bulky in others. I confirm it with my cooking digital probe thermometer. The bonus digital thermometer it came with has been super helpful, and is accurate.

"Bought the 300W one."

Per my thermometers, they are all staying constant. I will be ordering more of these in the future. My marina heater takes a few hours. All seem to vary between 1-2 degrees of each other which doesn't concern me much. The suction cups are large, high quality and seem to stick great. Once attached to the tank wall I've had no issues with it coming off. This is only day one though, so I shall keep an eye one it.

There is no protection from it banging on the glass tank. This has the best controller that I have found on the market. I wouldn't buy any other heater, unless one of these stops working.

"This heater is excellent."

Would be great to be able to tune that to. I would definitely recommend this product. I got this heater for my 55 gallon aquarium. And I get to keep the first one I bought! Bought it as a chiller for the k40 CO2 laser. But my guys don't read them and don't listen! Very easy to install and the adjustable temperature gauge is pretty accurate.

This product came in the nick of time! Bought it as a chiller for the k40 CO2 laser. If the blue light is flashing it means the heater is not fully submersible. If the water runs low or air gets in the heater shuts off. --The cylinder or rod diameter is bigger. I think it works well to not stand out like other heaters.

--Temperature adjustment labeling is on top rather than on the rod. What more could you ask for great job Hygger Duncan. --The heater itself is a bit shorter if your tank is a short one. The setting always stayed the same. So when I first received it it didn't work and I was very disappointed. Was very impressed with the quality of this heater. No biggie, but annoying nonetheless.

Keeps the temperature within 1 degree of what you set it to at all times. The cover over the heating tubes is great, the turtles claws can't damage the tube.
