Medium which is for 30-40
A 2 gallon difference shouldn't be a problem at all.
However, I would keep an eye on the temp, because with my heat pad and lamp going the temp gets just 2-3 degrees too high so I'm getting a lower wattage bulb soon.
But with a new heat source, no matter what it is, you should always keep an eye on the temp when you first get it, especially pads because you can't control the amount of heat they give off. Hope this helps!
