VIVOSUN Final Thoughts

"I bought the 7."

It is a bonus that the heater is titanium. I use a 50 for a 5 gal and a 10 gal tank. Sometimes it gets outside of it's ability to cool but only within a few degrees. I contacted the manufacturer and they sent me a new unit in less than a week! But my guys don't read them and don't listen! It took about an hour to reach 80f, which is fairly quick. I used to try those other cheap heaters sold on amazon.

"16-26 gallons 75 watt 10."

Keeps the temperature within 1 degree of what you set it to at all times. It's pretty noticeable, but I don't really care. I bought a similar one at the pet store and it barely worked. This is a great heater that is very easy to set up and program. And kids love pushing all sorts of buttons. 210 gallon ones and one 90 gallon bow front tank. Checked the accuracy of the heater with an infrared thermometer.

"Pricing was good."

This has the best controller that I have found on the market. The temperature lights up so it's very easy to read. I have a 10gallon tank that was at 72 degrees. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. Checked the accuracy of the heater with an infrared thermometer. Now, both points are clear on the package instructions. This little heater is perfect; this is our third purchase of the same heater.

"Until the next time."

I wouldn't buy any other heater, unless one of these stops working. Easy enough to let it run all the time. I'm not a big fan of the big glass tubes. They promptly fixed the issue without any delays or drama. It took me a few days slowly turning the dial up to finally get it where I wanted. I noticed my old hygger heater beginning to fail and my wife ordered this one. Sometimes it gets outside of it's ability to cool but only within a few degrees.

HITOP Final Thoughts

"The seller was wonderful."

The heater is super thin and the reflective surface is interesting. The design is sleek and modern looking. Ick for instance detaches from fish at 86 degrees and dies at 89. This is a powerful heater that holds temperature very well. We wish the controls were available in Farenheit also to make things a little easier. Just be careful and keep an eye on your temp settings when you have kids over! So far I like it setup was super easy.

Very easy to install and the adjustable temperature gauge is pretty accurate. Two inches above that is a waterline for maximum. This is a great heater that is very easy to set up and program. The temperature difference was very minor.

"Overall happy."

At this time I highly recommend this product. I wouldn't buy any other heater, unless one of these stops working. The controller is easy to use, very accurate and reliable. Personally for me the housing doesn't bother me. So if you set it to 78 degrees, the heater will not kick on until it reads 76. --Temperature adjustment labeling is on top rather than on the rod. The heater is being used in a 40 gallon breeder.

This has been in my fish tank for a few months now and it's been absolutely perfect! Checked the accuracy of the heater with an infrared thermometer.

"5 gallon tank."

The suction cups are large, high quality and seem to stick great. My fish likes to get close to it and he has never been hurt by it. I noticed my old hygger heater beginning to fail and my wife ordered this one. I have only had minor problems with the suction cups. Keeps the water consistent and it's easy to adjust! I love the heater otherwise, but I'm afraid some water has gotten inside the heater. Two inches above that is a waterline for maximum.

"What a long."

It just cycles through to 93f and starts over. Bought it as a chiller for the k40 CO2 laser. I had a thermometer on opposite side of tank and the heater was dead on true. This has the best controller that I have found on the market. The cover over the heating tubes is great, the turtles claws can't damage the tube. It does blend well in some setups and may look bulky in others. After several weeks of running the heater.
