THIS COOKED MY FISHES AND I BOUGHT TWO OF THESE , i set it up accordingly and when I came back to check on my fishes they were floating and the water was hot . It kinda sucks cause marine fishes are expensive but I didn’t have many in there thank god . I wouldn’t recommend this to anyone

I followed the instructions & the heater never came on. I am using a 10 gallon tank, left it under water for 45 mins just to be sure & then plugged it in. I don't understand why this is not working & was looking forward to this. ;(

Keeps the fish tank at 78°. At all times.It's small just perfect for a 5 gallon tank. it's perfect it stays in the corner of the tank. My little fish sometimes kisses the water heater. I guess he appreciates staying at a specific temperature at all times. when he goes in the corner with the water heater,he stays by it. Maybe the warmth that it gives off.
Temp too low

I have a 5 gallon tank and only fill it with 4 gallons of water. After three days, this heater still won’t heat the water above 76. The light turns on when plugged in and turns off within an hour as if the water is 78. I even moved thermometer right next to it and it still was at 76.

This aquarium heater got to me quickly, but sadly after about a week it gave out. It is no longer heating the water at all. The light will not come on anymore. I’ve tried a few things to address the issue, but it is broken.

I got this yesterday and its already heated up most of my 10 gallon tank, my betta loves it, he’s constantly swimming around it and is forming a little bubble nest around it. We’ve been calling it his girlfriend because he loves it so much.

I would like to write a review on it but it doesn’t even work straight out of the package. It’s nice and small which I appreciate but it doesn’t work. So I’m returning it

So I put this in the tank, waited a little over 30 minutes and nothing happened when I plugged it in. Gave it two days and the light never came on and it never put out heat. Do not waste your money buying this
This item works!

It only works if you use it correctly. Read the instructions, the light doesnt stay on constantly, only when its on and if its not turning on your water temp should already be the right temperature. Im using the 50 watt one for a 10 gallon tank and my little betta is happy!
Its not the best of worst

It does heat up the tank but definitely not to where it is supposed to be temperature wise. Also wont stick to the side of the tank very well
