I had one of the tetra heaters and it never actually turned on but that was a couple of years ago so I will try that first since its the cheapest and I can get faster shipping. I looked at the 100w one and most people had them for 25g or more. That won't affect my tank right? That just means it won't work as hard?
Using a large heater on a 3g tank might be a bit overkill. I'm not sure how sensitive the thermostat is on those heaters but they will most likely heat the water faster than the thermostat can regulate it. I would opt for the smaller version of the heater if at all possible
