AquaTop GH-50W First Impressions

"Works as intended."

My fish likes to get close to it and he has never been hurt by it. You don't have to worry about wide temperature swings with this unit. I like to keep it at 72 and from my thermometer it is reading at exactly 72. This product came in the nick of time! I recieved this product without the instructions or the added thermometer. It's pretty noticeable, but I don't really care. --The heater itself is a bit shorter if your tank is a short one.

AquaTop GH-50W Final Thoughts

"Works great."

I'm in the process of setting up for tanks. Also were nice along the whole process. The line is there due to regulations in certain countries. I went ahead and went with the the larger 300W for my 45 gallon. Ick for instance detaches from fish at 86 degrees and dies at 89. This is a great heater that is very easy to set up and program. We would consider a replacement and then we would return the defective unit.

"Same suckers for years!"

Keeps the water consistent and it's easy to adjust! Takes a little while to drop the temps if it is hot in the garage. Sometimes you may have to tinker around with the dial. The temperature difference was very minor. This has been in my fish tank for a few months now and it's been absolutely perfect! Those turned out to be a hit and miss. Once I opened the box i noticed the quality of the construction.

AquaTop BC003408 Final Thoughts

"I like the size."

I love the heater otherwise, but I'm afraid some water has gotten inside the heater. The heater is super thin and the reflective surface is interesting. All seem to vary between 1-2 degrees of each other which doesn't concern me much. Temperature is slightly off by running a little warmer. Maintains it well except when the weather is already warm then it over heats it. Keeps the water consistent and it's easy to adjust! You program it for temperature you want your tank to be.

"Just bought a second one!"

It does blend well in some setups and may look bulky in others. I have only had minor problems with the suction cups. I hope these suction cups work very well. The setting always stayed the same. So when I first received it it didn't work and I was very disappointed. The temperature gauge is fairly accurate in my 55 gallon tank. This heater is NOT fully submersible.

For Discus you need warm and accurate heater and this seems to do the trick. Now, both points are clear on the package instructions. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. So far I like it setup was super easy. Come on Fluval, expect better from you. We would consider a replacement and then we would return the defective unit. I left seller feedback yesterday but have yet to hear from the seller.

"No copper lines!"

I used to try those other cheap heaters sold on amazon. No biggie, but annoying nonetheless. It is a bonus that the heater is titanium. My heater is fully submerged underwater and works perfectly fine. The heater is easy; turn the dial to set temp and plug in. --The heater itself is a bit shorter if your tank is a short one. There is no protection from it banging on the glass tank.

"This is a quality heater."

Checked the accuracy of the heater with an infrared thermometer. Two inches above that is a waterline for maximum. I use this little heater for my 10 gallon quarantine tank. You program it for temperature you want your tank to be. This is a powerful heater that holds temperature very well. It just cycles through to 93f and starts over. I will definitely be buying another one for my other tanks at bigger one.

Well worth the money the first one I bought still works great. This has been in my fish tank for a few months now and it's been absolutely perfect!

Very easy to install and the adjustable temperature gauge is pretty accurate. 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. They shipped us the upgraded version that also heats! Personally for me the housing doesn't bother me. I wouldn't buy any other heater, unless one of these stops working. Also were nice along the whole process.

"Works fine."

But I am single and don't have to worry about this. I noticed my old hygger heater beginning to fail and my wife ordered this one. I have a few of these and I use them in my 55 gallons tanks and a 29 gallon tank. Well I bought a second one took me only one trying to get the right temperature. So if you set it to 78 degrees, the heater will not kick on until it reads 76. No biggie, but annoying nonetheless. I went ahead and went with the the larger 300W for my 45 gallon.

If the water runs low or air gets in the heater shuts off. This heater warmed it right up and now my Betta and guppies are more active. We would consider a replacement and then we would return the defective unit. The temperature has been holding all day, even in a colder room. It is a bonus that the heater is titanium. It just cycles through to 93f and starts over. Seems to keep the temp n the tank fairly regular.
