Because I cannot use my house water for my aquarium, I have a friend that gives me 25 gallons of water a month, love this guy...I have to put this water in two 5 gallon buckets to heat it up to the water heat of the aquarium. To do this, I put 2 of these Preset Heaters in each bucket. Bingo! perfect size and perfect heat...Yes, I do recommend this heater for small aquariums or to heat up cold water....and don't forget the price.....did not have to rob a bank to get the two.
Cancer warning on package
on Jul 12, 2020
I never actually ended up using this item, as after it arrived I read the package and noticed a warning on the back about it containing elements known to cause cancer by the state of California. I know a lot of things cause cancer these days, but I really don’t want to risk giving my Musk turtle cancer! I am going to find a different heat source for him, probably an additional heat lamp.
Betta LOVES it
on Jul 25, 2020
Got this for my 5gal tank and my Betta immediately went to the heater! I positioned a plant pretty close so now that’s where he likes to sleep and relax when he’s not swimming all around! Definitely keeps the whole tank a steady temperature, I have checked to make sure it wasn’t getting too hot anywhere.
Betta fish likes it.

I have a 10 gallon tank. It does heat up the tank, I’ve left it running for a few days before putting my betta in with it. He likes it, he’s actually started a bubble nest around the heater. READ THE INSTRUCTIONS! It can be very easy to install it wrong, it won’t work like you would like it too unless properly installed.

I truly like this little heater! Just set it in the tank and go! It is submersible so it works with pretty much any size aquarium- I have 1 in 2 different aquariums without ay problems so far

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. ;(

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.
Aqueon aquarium water heater

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.
