Aqueon Preset Heater, 100 Watt

Constantly running on a 20 gallon mixed reef tank for the past 11 months as a backup secondary heater and worked great. I removed my main heater to for a few hours for maintenance and let this preset heater in the tank only. I noticed the temperature drop to below 75 degrees f (almost 3+ degrees below preset of 78). Contacted Aqueon as it is still under warranty and now they are sending me a replacement unit. Great customer service, too.

I was shocked about how good this item is. When it first came, I thought it would overheat my tank, but I had to give it a try. So when I placed the heater in, the suction was pretty secure! I was surprised by this, because lots of heaters' suction power does not stick well. It gets better and better! I turned on the heater and I saw the red light. I waited for a few more minutes and the light went down. At first, I thought I didn't plug the cable well, but after a while, I realized it was actually controlling the temperature in the tank. Amazing! It turned on and off, on and off. Then I checked the temperature in the tank. It was perfect! Overall, this heater is a solid 5 star!

Excelente calidad. Funciona perfectamente. Mantiene la temperatura ente 24 y 25 grados. Lo uso en un acuario de 60lts

Very pleased. I’d always thought aquarium heaters would be expensive and for very serious, high-budget aquarium aficionados. I’m thrilled that I can offer a little heater to my betta! I was worried about his water becoming too cold in winter. Now I can keep his tank warm without worrying about the overall room temperature. Great buy! I don’t love the look, but once you’re used to it, it’s just part of the tank. The alternative is to heat the entire room to temperature at all times, which is just unnecessary, so the aesthetic tradeoff is worth it.

Buen producto, marca me gusta mucho, llegó en buen estado y funcionando bien
