Heater Question

I have a 25W heater for my 20 gallon tank. It keeps the water temp to 25-26 degrees celcius (77-78.8 fahrenheit). Is this enough wattage because what if I am overworking the heater? My thinking is that it's safer to go low wattage in case the heater short circuits and doesn't know when to stop heating.

For a 20G, you want to use a heater at least 100W. Generally, 5W per gallon. You might stress your heater if it is unpower. Espicially the days are getting colder now.

That won't really affect whether or not your heater will fail in the on position. Your heater will use the same amount of watts regardless. The only benefit I could think of is that using fewer watts will mean that it will take longer for your tank to overheat if it does fail.

P.S. the way you would overwork a heater is by keeping it on too long, which would happen if your tank was not up to temp, which is more likely with a lower watt heater.

Okay update. Thanks a lot for the advice. I upgraded to a 75W heater. Forgot the brand. Cost my 31.99 + tax. It's temp adjustable. Only regret is that it noticed it wasn't 100% submersible after I bought it. Going to use the 25W for my nano 2.5 .
