Aqueon Adjustable PRO Aquarium Heater Up to 100 Gallons, 300 Watts

I bought this heater for a 55 gallon tank. It has worked flawlessly for 2 years now. It keeps a constant temp and very accurate. I have never had to adjust it at all. Highly recommend.

[This review was collected as part of a promotion.] This was an outstanding heater for our salt water tank. It heated up quickly, and maintained the temperature as needed. Definitely recommend this, especially for a saltwater tank. Would buy again in a heartbeat!

[This review was collected as part of a promotion.] What an amazing little powerful aquarium heater! What's great is that you can have a tank as small as 5 gallons and can heat up to 100 gallons! This is great for any fish that require heat. It is so accurate as well so you won't have any issues with getting it to the temperate you need. Highly recommend to all aquarium owners out there

[This review was collected as part of a promotion.] We have several large aquariums and always need quick replacement heaters when something goes wrong. We swapped this in and were pleased with the ease of installation and how quickly it got to temperature. We will be ordering more in this line.

[This review was collected as part of a promotion.] The heating range on this Aqueon Pro Heater 300 W is amazing, going up to 100 gallons! The heat adjustment is easy to use and understand and the electronic thermostat is so useful. The cool feature I love about this heater is that there is a gravity shut off feature so that when the top of the heater tilts below the bottom it turns off. The less likely there is for an accident the better.

[This review was collected as part of a promotion.] Keeps the water warm without being too hot or cold. I used it with one of the tanks offered through Influenster!

[This review was collected as part of a promotion.] I love this heater, mostly because I can use it in the tank I need it no matter the size. Love it! Five stars.

[This review was collected as part of a promotion.] Very easy to install even for a beginner like myself. Keeps your tank at an even heat and the temperature can also be adjusted if needed. Works very good.

Works great but takes little longer to heat up a 100 75 gallon tank.

Purchased about 15 months ago and heater worked well but LED light always did a weak flicker. Yesterday I came and checked my tanks temp and it was 86F when my settings are 78F. I tested this thing again in 72F water with a setting or 78F and it continued to heat the water past 83F. I stopped the test and this thing isn't reliable. All the reviews are great but the this not lasting a few years or having a working safety shutdown sucks! (All temperatures verified by mercury thermometer and two different digital thermometers)
