"What a long."Easy enough to let it run all the time. Also I like how it shows both the current temperature and the set temperature. Once I opened the box i noticed the quality of the construction. The controller is easy to use, very accurate and reliable. They promptly fixed the issue without any delays or drama. I will definitely be buying another one for my other tanks at bigger one. Those turned out to be a hit and miss.

"Will update in a month."So if you set it to 78 degrees, the heater will not kick on until it reads 76. It would stick out of my 30 g wide tank if I were to put it vertical. This is a great heater that is very easy to set up and program. I am very happy with this purchase. This is only day one though, so I shall keep an eye one it. Easy to read the temp and know exactly how warm the water is. I like to keep it at 72 and from my thermometer it is reading at exactly 72.

Aqueon 100101230 First Impressions
"FIVE STARS!"You don't have to worry about wide temperature swings with this unit. I have a 10gallon tank that was at 72 degrees. It took about an hour to reach 80f, which is fairly quick.

When i installed them, i let them sit in the tanks without power for 6-24 hours.

"5 degrees."The temperature difference was very minor. I hope these suction cups work very well. I am very happy with this purchase. --The heater itself is a bit shorter if your tank is a short one. Seems to keep the temp n the tank fairly regular. It took me a few days slowly turning the dial up to finally get it where I wanted. We received the chiller promptly and put it into use.

"Well written but vague."We would consider a replacement and then we would return the defective unit. Once attached to the tank wall I've had no issues with it coming off. This this is amazing and is worth the money. Also were nice along the whole process. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. The heater is super thin and the reflective surface is interesting. So if you set it to 78 degrees, the heater will not kick on until it reads 76.

"Amazing customer service."The setting always stayed the same. After several weeks of running the heater. Am a totally sold customer and would recommend them to anybody! I hope these suction cups work very well. You don't have to worry about wide temperature swings with this unit. It's pretty noticeable, but I don't really care.

"Thank you for reading."I got this heater for my 55 gallon aquarium. Checked the accuracy of the heater with an infrared thermometer. There is a misconception on the internet that the heater isn't fully submersible. What more could you ask for great job Hygger Duncan. The temperatures are pretty accurate.

"Works great."We would consider a replacement and then we would return the defective unit. I tested it by unplugging and replugging it. I'm not a big fan of the big glass tubes. I emailed the email it says to and told them. They promptly fixed the issue without any delays or drama. Per my thermometers, they are all staying constant. This product came in the nick of time!

"I like the size."I love the heater otherwise, but I'm afraid some water has gotten inside the heater. The heater is super thin and the reflective surface is interesting. All seem to vary between 1-2 degrees of each other which doesn't concern me much. Temperature is slightly off by running a little warmer. Maintains it well except when the weather is already warm then it over heats it. Keeps the water consistent and it's easy to adjust! You program it for temperature you want your tank to be.

"I like this heater."I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. Per my thermometers, they are all staying constant. I'm not a big fan of the big glass tubes. I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. Come on Fluval, expect better from you.

"5 stars in my book!"--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.

"I have a betta in a 1."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. I will be ordering more of these in the future. I will be ordering more of these in the future. Now, both points are clear on the package instructions.

"5 or even."All seem to vary between 1-2 degrees of each other which doesn't concern me much. The bonus digital thermometer it came with has been super helpful, and is accurate. For Discus you need warm and accurate heater and this seems to do the trick. There is a misconception on the internet that the heater isn't fully submersible. If the water runs low or air gets in the heater shuts off. And kids love pushing all sorts of buttons. Personally for me the housing doesn't bother me.
