So I got a 30 gallon tank off craigslist and I need a new heater for it.
So what size heater should I get for my 30 gallon?

Maybe. IF the room temp won't vary greatly from the tank temp. I keep my house at 65-67 and if I need to maintain a temp of 78-80 a 100w heater will just not cut it. I'd spend the extra dollar or two and go to a 200w heater. There's more than just the 5w/gallon equation that should be taken into consideration...Yep, but an 100 watt will just about cut it too. Depends on how different the ambient temp is from your desired temp, I suppose.
