Hi. Congrats on the new tank; I'm sure you'll have lots of fun with it. I really enjoy mine. Have you already bought the heaters? If not, you might consider getting 2 x 150W heaters. It'll only cost a few dollars more and will be a little extra power in case the room ever gets cold. That's just my opinion though... i have a 300W heater in my tank and have had good luck with it.
