20 Gallon Tank How many watts do I need for my tank?

MyFishAddiction

What size heater for a 25 gallon tank? I have heard 100 watts.

100 or 150 watt should be plenty fine. Or even a 125 watt. The basic figuring is 5 watts per gallon.

Room- 68-74 typically desired- 75-80. I probably shouldn't need a heater much now till bout september.

yeah i think 100 watts is more then efficient if its no more then an 7 or 8 degree difference between room temp and desired tank temp. as Betta'sAnonymous said maybe 125 watts would be best once winter arrives and you get those colder nights. and tbh the 150 may be ideal. me personally i keep my heat around 68-72 in the winter and i need a quality 150 watt in my tanks to keep them warm. a lower watt may get the job done, but it will probably be on consistently. its probably a small difference in price for the higher wattage.
