Tetra 26445 First Impressions

"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.

"Very pleased so far."

Also were nice along the whole process. I have a 10gallon tank that was at 72 degrees. We would consider a replacement and then we would return the defective unit. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. The temperature difference was very minor. --Temperature adjustment labeling is on top rather than on the rod. I waited a little bit to write the review so it could be accurate.

"Quality was amazing."

It would stick out of my 30 g wide tank if I were to put it vertical. Well worth the money the first one I bought still works great. We received the chiller promptly and put it into use. But I am single and don't have to worry about this. Or better yet, conceal it to the back corner. If the water runs low or air gets in the heater shuts off. I'm in the process of setting up for tanks.

"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.

"Very pleased so far."

So when I first received it it didn't work and I was very disappointed. I was amazed how quickly I got to my temperature I need it 78 degrees. The suction cups are large, high quality and seem to stick great. I wouldn't buy any other heater, unless one of these stops working. It took about an hour to reach 80f, which is fairly quick. I got this heater for my 55 gallon aquarium. I have 3 of the Fluval heaters, in various sizes.

When overheating (more than 93 Fahrenheit), it will automatically shut down, and it will automatically reset when it cools to the starting temperature (usually two degrees lower than the set temperature).

"They contacted me."

This does a great job at regulating the temp in my 10 gallon. I like the fact that it comes with a digital thermometer. This heater works, but the dial it isn't very accurate. I wouldn't buy any other heater, unless one of these stops working. I have only had minor problems with the suction cups. I like how the heater is constructed. Beware, but we are hoping for a good outcome!

"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

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.

It is suitable for fresh water and sea water! Please confirm the wattage, tank capacity and other details before purchasing to select the aquarium heater with appropriate wattage.
  • 【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.

UPMCT Final Thoughts

"No issues."

All seem to vary between 1-2 degrees of each other which doesn't concern me much. The temperature gauge is fairly accurate in my 55 gallon tank. I would definitely recommend this product. The red light means it's off, blue light means the temperature is constant. I got a hold of Amazon, who put me in touch with the seller. Ick for instance detaches from fish at 86 degrees and dies at 89. No biggie, but annoying nonetheless.

The setting always stayed the same. Awesome chiller, perfect for Hydroponics. Takes a little while to drop the temps if it is hot in the garage. It just cycles through to 93f and starts over. I hope these suction cups work very well. This this is amazing and is worth the money. We received the chiller promptly and put it into use.

"6 gallon tank."

I had a thermometer on opposite side of tank and the heater was dead on true. The bonus digital thermometer it came with has been super helpful, and is accurate. Sometimes it gets outside of it's ability to cool but only within a few degrees. They shipped us the upgraded version that also heats! I love the heater otherwise, but I'm afraid some water has gotten inside the heater. For Discus you need warm and accurate heater and this seems to do the trick. Those turned out to be a hit and miss.
