I had to buy a second heater for my 55 gallon tank because it didn’t adequately heat. I’m sure if would be ok for small tanks though.
Best heater I’ve ever used and I’ve tried many! Use the 50 watt for a 20 gallon long Betta tank. Keeps water at perfect 79 degrees.
This is by far the worst heater I have ever invested in. I placed it in a 75 gallon saltwater aquarium two days ago checked this morning and it is completely full of water and has put toxic chemicals inside of my salt water tank killing all fish. Do not buy!!
I recently noticed that my tank is no longer warm and fish started to die off. Finally realized the heater was not working anymore and I bought it less than 2 months ago.
Heater worked good for a few mouths then just stopped working
