Hey southernstang, I believe it's a 100W. I just plugged it in and it works as it should. I live in Millington,TN...about 10 minutes north of Memphis on hwy51. You can have it if you bring me a pack of Kool Milds in the box (blue box).
Hey Keaton...the 10 would work, but it would be crowded. Are you running a HOB skimmer or are you planning on putting it in the sump? Are you going to put your return pump in the sump or are you going to use an external pump? Are you going to run carbon in your sump all the time or just some of the time?
To be honest with you, Barrett is the master when it comes to the sumps. He could give you some pointers or possibly build you a sump.
Hope I helped...
