"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.

"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. Awesome chiller, perfect for Hydroponics. All seem to vary between 1-2 degrees of each other which doesn't concern me much. The setting always stayed the same. 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.

"I have a 5."

You don't have to worry about wide temperature swings with this unit. I have it set to 81F to get a 77F water temp. The heater protector was very heavy plastic and slim lined which is great. Also were nice along the whole process. The temperature has been holding all day, even in a colder room. Well I bought a second one took me only one trying to get the right temperature. I contacted the manufacturer and they sent me a new unit in less than a week!

"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.

"They contacted me."

All seem to vary between 1-2 degrees of each other which doesn't concern me much. I use this little heater for my 10 gallon quarantine tank. This heater warmed it right up and now my Betta and guppies are more active. This product came in the nick of time! You program it for temperature you want your tank to be. After several weeks of running the heater. Beware, but we are hoping for a good outcome!

You don't have to worry about wide temperature swings with this unit. It's pretty noticeable, but I don't really care. It took me only two tries to get it to the correct temperature.

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. I was worried about the quality but I am thoroughly impressed with this heater!

"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!

"This is a quality heater."

I have 3 of the Fluval heaters, in various sizes. It's pretty noticeable, but I don't really care. We received the chiller promptly and put it into use. Just be careful and keep an eye on your temp settings when you have kids over! This heater is NOT fully submersible. No biggie, but annoying nonetheless. It does blend well in some setups and may look bulky in others.

"Looks as advertised."

I got a hold of Amazon, who put me in touch with the seller. Once attached to the tank wall I've had no issues with it coming off. I adjusted the set temperature a little lower to be more in the range I wanted. --Temperature adjustment labeling is on top rather than on the rod. I had a thermometer on opposite side of tank and the heater was dead on true. --The cylinder or rod diameter is bigger. But my guys don't read them and don't listen!

This heater warmed it right up and now my Betta and guppies are more active. But my guys don't read them and don't listen! I was amazed how quickly I got to my temperature I need it 78 degrees. Personally for me the housing doesn't bother me. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. The temperatures are pretty accurate. I'm in the process of setting up for tanks.

"So far so good."

The heater is easy; turn the dial to set temp and plug in. My heater is fully submerged underwater and works perfectly fine. It does blend well in some setups and may look bulky in others. The suction cups are large, high quality and seem to stick great. Well worth the money the first one I bought still works great. Bought it as a chiller for the k40 CO2 laser. Keeps the water consistent and it's easy to adjust!

"Love this heater!"

It is safe and dependable and comes with a one year warranty. I was worried about the quality but I am thoroughly impressed with this heater! I dont know, and havent tried just yet. We wish the controls were available in Farenheit also to make things a little easier. Beware, but we are hoping for a good outcome! I dont know, and havent tried just yet. Come on Fluval, expect better from you.

  • UPMCT Aquarium Heater, 50W 100W 300W Submersible Fish Tank Heater with Thermometer Strip Adjust Knob Thermostat, Suitable for 5 to 85 Gallons
  • 【Quality Assurance】High-purity thick quartz explosion-proof crystal tube is used on the surface, there will be no rust spots, causing heavy metal damage to the fish. The double sealing waterproof can also prevent electric leakage, the fish will not be electrocuted due to leakage of the product. A heating guard with a high suction cup is provided as a gift, and the fish will not be burnt due to the fish touching the aquarium heater. Keep your fish live in a carefree warmth at any time!
  • 【Wide Range Of Temperature Adjustment】Bimetallic material, precise temperature control. Adjustable temperature ranges from 68°F to 94°F(20°C - 34°C), and you can choose the coziest temperature for your fish. (The suitable temperature range for most tropical fish is 76°F to 80°F/24°C -27°C ). At the same time, a temperature sticker is attached to the fish tank, allowing you to intuitively detect temperature changes at any time, so that you can use it with more confidence.

  • 【Easy To Install】Can be installed vertically or horizontally, but the aquarium heater must be completely submerged in water. We also recommend placing it near a strong water flow, where the outlet of the mains filter is ideal, so that the temperature of the entire aquarium is the same.
  • 【How To Use】Immerse the aquarium heater completely into the aquarium or tank, wait for 10-15 minutes to let the internal temperature adapt to the actual water temperature in the tank. Then twist the thermostat knob, adjust the temperature to 68°-94°F and then connect to the power supply.

I got the 200W variant for my 54 gallon corner tank that's housing goldfish. When i installed them, i let them sit in the tanks without power for 6-24 hours. This little heater is perfect; this is our third purchase of the same heater. So far I like it setup was super easy. They promptly fixed the issue without any delays or drama. I hope these suction cups work very well. The heater is easy; turn the dial to set temp and plug in.
