Easy enough to let it run all the time. The controller is easy to use, very accurate and reliable. I have only had minor problems with the suction cups. The suction cups are large, high quality and seem to stick great. Bought it as a chiller for the k40 CO2 laser. I have 3 of the Fluval heaters, in various sizes. You don't have to worry about wide temperature swings with this unit.

"Until the next time."

I got the 200W variant for my 54 gallon corner tank that's housing goldfish. I think it works well to not stand out like other heaters. Checked the accuracy of the heater with an infrared thermometer. You don't have to worry about wide temperature swings with this unit. I noticed my old hygger heater beginning to fail and my wife ordered this one. The heater is super thin and the reflective surface is interesting. Two inches above that is a waterline for maximum.

I have had to turn the dial to about 78-79 for the tank to stay around 76 degrees. Per my thermometers, they are all staying constant. I'm not a big fan of the big glass tubes.

"Yes, you read that right."

I was worried about the quality but I am thoroughly impressed with this heater! I will definitely be buying another one for my other tanks at bigger one. We received the chiller promptly and put it into use. I emailed the email it says to and told them. This heater warmed it right up and now my Betta and guppies are more active. I waited a little bit to write the review so it could be accurate. The temperature lights up so it's very easy to read.

The red light means it's off, blue light means the temperature is constant. I have only had minor problems with the suction cups. It comes with a hanging kit and can be secured on the edge of the tank. The heater is being used in a 40 gallon breeder. No biggie, but annoying nonetheless. Once attached to the tank wall I've had no issues with it coming off. The heater is super thin and the reflective surface is interesting.

Well worth the money the first one I bought still works great. Maintains it well except when the weather is already warm then it over heats it. I tested it by unplugging and replugging it. I have it set to 81F to get a 77F water temp. This heater is NOT fully submersible. Sometimes you may have to tinker around with the dial.

So if you set it to 78 degrees, the heater will not kick on until it reads 76. This this is amazing and is worth the money. They shipped us the upgraded version that also heats! The temperature has been holding all day, even in a colder room. I think it works well to not stand out like other heaters. I love the heater otherwise, but I'm afraid some water has gotten inside the heater. I was worried about the quality but I am thoroughly impressed with this heater!
