Aqueon® Submersible Aquarium Heater
I had 200W unit for nearly 7 months and it struggles to maintain temperature when it gets cold outside. Also within two weeks plastic safety knob start melting. It died and shocked all my fish. Spend $20 more and get a Eheim Jäger unit.

Works great so far.
I purchased this today after I broke my other heater. The 50w is much smaller than the Nat Geo 50w heater. This one is also easier to access. I don't have to take the whole heater out to change the temperature. It keeps my tank a constant 80, as I have it set at that temperature.

Extremely easy to assemble and keeps my tank at a perfect 76 degrees. I've had no problems what-so-ever and my fish love this heater:)

One hot item!
This is the first heater I would recommend to a friend, or anyone else.
I had a Very negative experience with my last heater, thankfully, I was only cycling my new aquarium, and had a few minnows in it.
This one, I set to 80, and 80 degrees it has been night and day for 2 weeks. Love this heater. If you don't want your fish to freeze, or fry, I recommend this heater. it does a great job.
Advice, ALWAYS test Any heater out first before putting it in with your prized fish.
