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.

"The seller was wonderful."

This does a great job at regulating the temp in my 10 gallon. There is no protection from it banging on the glass tank. Pressing and holding the button for 5 seconds changes it from F to C readouts. Temperature is slightly off by running a little warmer. I'm not a big fan of the big glass tubes. I wouldn't buy any other heater, unless one of these stops working. My marina heater takes a few hours.

hygger Final Thoughts

"No copper lines!"

I will definitely be buying another one for my other tanks at bigger one. The red light means it's off, blue light means the temperature is constant. The suction cups are large, high quality and seem to stick great. The line is there due to regulations in certain countries. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. --The cylinder or rod diameter is bigger. I used to try those other cheap heaters sold on amazon.

"I bought the 7."

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.

"Bought the 300W one."

Personally for me the housing doesn't bother me. I used to try those other cheap heaters sold on amazon. Sometimes it gets outside of it's ability to cool but only within a few degrees. There is a misconception on the internet that the heater isn't fully submersible. Easy enough to let it run all the time. I noticed my old hygger heater beginning to fail and my wife ordered this one. This heater warmed it right up and now my Betta and guppies are more active.

"So far it seems great!"

I tested it by unplugging and replugging it. The red light means it's off, blue light means the temperature is constant. The heater is easy; turn the dial to set temp and plug in. It's pretty noticeable, but I don't really care. The temperature gauge is fairly accurate in my 55 gallon tank. This this is amazing and is worth the money. After several weeks of running the heater.

"Seems very well built."

It is a bonus that the heater is titanium. If the blue light is flashing it means the heater is not fully submersible. Once attached to the tank wall I've had no issues with it coming off. Pressing and holding the button for 5 seconds changes it from F to C readouts. There is a misconception on the internet that the heater isn't fully submersible. I like to keep it at 72 and from my thermometer it is reading at exactly 72. You don't have to worry about wide temperature swings with this unit.

"Easy to unpack."

This heater warmed it right up and now my Betta and guppies are more active. My heater is fully submerged underwater and works perfectly fine. I bought a similar one at the pet store and it barely worked. The temperatures are pretty accurate. Temperature is slightly off by running a little warmer. I use a 50 for a 5 gal and a 10 gal tank. I got this heater for my 55 gallon aquarium.

"9 degrees."

Would be great to be able to tune that to. But I am single and don't have to worry about this. --The heater itself is a bit shorter if your tank is a short one. I recieved this product without the instructions or the added thermometer. I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. Keeps the temperature within 1 degree of what you set it to at all times. I like the fact that it comes with a digital thermometer.

I was worried about the quality but I am thoroughly impressed with this heater! I adjusted the set temperature a little lower to be more in the range I wanted. My fish likes to get close to it and he has never been hurt by it. Keeps the water consistent and it's easy to adjust! You program it for temperature you want your tank to be.
