DaToo 50 Watt Aquarium Heater Submersible Adjustable Temperature Fish Tank Heater 50W

This is perfect for my 10-gallon molly fry tank, and I really like the included sticker thermometer.

it works great in my tank ty

This is for 10 maybe 15 gallons max depending on your ambient temp fyi

works well in my 20 gallon and 10 tank you

Works. And it's actually pretty accurate, the set temp is matching my floating thermometer

Reliable to keep our Betta fish warm in his tank.

Works great. Just a little hard to adjust. Sticks.

There wasn't a way to set the temperature. The whole thing fell apart exposing wires and such. The most disturbing thing was that the glass tube shattered with the tiniest bump. I can't imagine what could have happened if it were inside the tank when it happened.

I think something is wrong bc my water is still not warming up even though the red “on” light is on and it is near the filter.

was broken when rcvd didnt realize and was shocked when going to adust it
