Aqueonプリセットヒーター、100ワット

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

This heater is fine provided you are ok with it being off the rated 78*F a slight bit. Mine kicks in at 77* and then the red light goes on and it holds steady at 77*F in a 20 long and rarely lights to maintain temp. Even though my room temp was 73*, my LED tank lights were high enough to make it never actually light until I tested with ice cubes and a thermometer. It's liertally half the size of the top rated German 100 watt which won't even fit well anywhere but the back and the black and small size makes it blend well in a planted with dark substrate. Long term reliability is iffy at under $15 based on Utube vids but so far, I am very happy. Only a 6 footish cord, so you may need an extension from the outlet, especially to place it low and horizontally.

I have 2 of these heaters in my 30 gallon tank just in case one goes out. Reliable, not a problem since.
