🎏【Care and Maintenance】To prolong the life of your aquarium heater, we recommend you clean your heater rod body frequently, please remember to unplug and cool it for 15-20 minutes before removing the heater rod housing.

Works great Iâd buy it again

Great price
This is a really early review but I bought the 300 watt for my freshwater aquarium with sump. Total water volume of around 46 gallons. Hooked it up and set the temp to 78 and it didnât take long at all to heat the water up to temp. I do have an infrared laser thermometer to check the temp and it was pretty much on the money. I havenât had a power outage to check if it goes back to my heat setting. But if all goes well in the future Iâll definitely buy another canât be beat for the money

Great product for aquariums

Love this heater
I love the big display and ease of setting up. It works well and heats super fast I got the 300w and my older one was on all the time. I also like the out of water feature which turns it off I canât say how many I broke forgetting to turn it off before removing. Itâs a great value and love the hideability it seems to be built well and I will purchase again if needed.

Best tank heater in ever bought.
This tank heater is excellent. It is extremely easy to install taking only minutes. It.is very well v constructed and appears to be durable. The glass tube is.protected by a hard plastic shield. I watched its first cycle and was surprised at how rapidly.it heated the tank. The controller is simple to use, read and very accurate. I checked its accuracy with a laser thermometer. The controller also.has a.mounting hole in the back for wall.mounting by screw or nail. Well.packaged. Arrived a day ahead of advertised schedule.

Not Accurate
At first, the register was only a degree lower than the actual temperature but after a week there is a 3 degree difference. I am worried that if I leave it in, the next time it will be 6 degrees actually higher and boil my fish. Wish there was another way to turn it off other than unplugging it.
