Easy to use

My daughter likes it

Good value

Easy to install. Does come lose at times from the side of the tank, but overall works great

Good Aquarium Heater

I bought this despite some bad reviews. Glad I did because it was inexpensive and is working perfectly. I use this 300w in my 110 tank. It struggles a bit but does keep the tank up around 76 where I wanted it. Would be perfect for a 50-90G tank. I'm keeping it!

Aqueon Submersible Aquarium Heater 300W

Takes a few days of playing with, but once you get it set to your tank it holds temp very well. Suction cups have to be put toward top away form heatiing element. If you do not do that it will make a load clicking noise as others have said when it is on. It's in a 120 gallon right next to the input of the Fluval FX4, it does not work hard at all but a bit scarry at first because it's not blacked out like others and it really glows when it's on at night. And the big plus it has not filled with water or condensation at all like Marineland garbage heaters. Finally I can trust the temp in the tank I check it quite often but we can go on vacation without the worry of our Marineland heater failures of many. All (4) tanks now have Aqueon heaters. We are very very pleased and impressed with these, after the many Marineland heater faiiures and returns, there is a heater god watching our fish thanks Aqueon. Our Aficans agree...

Aqueon Heater

Let me say this. It does what it says it will do...end of story. If you want to maintain a temp...buy this.

Works like a charm

I replaced the original heater that came with my aquarium. My guppies are happy and the tank is looking healthier.
