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.

"And I am glad I did."

--The cylinder or rod diameter is bigger. It's pretty noticeable, but I don't really care. This is only day one though, so I shall keep an eye one it. I wouldn't buy any other heater, unless one of these stops working. The heater is being used in a 40 gallon breeder. I emailed the email it says to and told them. I used to try those other cheap heaters sold on amazon.

SunGrow First Impressions

"5 gallon tank."

I went ahead and went with the the larger 300W for my 45 gallon. The heater is super thin and the reflective surface is interesting. The bonus digital thermometer it came with has been super helpful, and is accurate. We wish the controls were available in Farenheit also to make things a little easier. Bought it as a chiller for the k40 CO2 laser. Pressing and holding the button for 5 seconds changes it from F to C readouts. Beware, but we are hoping for a good outcome!

This way the heat is evenly distributed throughout your tank.

"Temperature!"

It would stick out of my 30 g wide tank if I were to put it vertical. It took about an hour to reach 80f, which is fairly quick. My fish likes to get close to it and he has never been hurt by it. Was very impressed with the quality of this heater. I left seller feedback yesterday but have yet to hear from the seller. I will be ordering more of these in the future. We received the chiller promptly and put it into use.

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.

"Works great."

This is a great heater that is very easy to set up and program. Beware, but we are hoping for a good outcome! Also I like how it shows both the current temperature and the set temperature. I recieved this product without the instructions or the added thermometer. Temperature is slightly off by running a little warmer. This little heater is perfect; this is our third purchase of the same heater. The line is there due to regulations in certain countries.
