50 watts too much for a 5 gallon?

Or is it good? I feel weird using a 25 watt because the max amount of gallons for 25 watts is 5 gallons. So I feel like I would prefer to have some extra.

Same here, they work awesome. I have one in my 10 gallon and one in my 5.5 gallon and they are always at a steady 79 degrees.

I just feel like the heater won't have to work as hard if it's a 50 watt, ya know?

Yesss! It just wont have to turn itself on as much or for as long since it is a smaller volume of water.
