Wecome to the forum, Sean.
I think that is a great selection for a tank. I started with a 46 bow myself and always liked the look of them.
For Powerheads, I use
Hydor Koralias. I have a 150 Reef Ready and I use a HK2, a HK3 and a HK4 for circulation, and I have an Eheim Compact+ 5000 for my return pump. I am currently running a reef, so I have a higher turnover rate, about 26X. I would think that an HK3 would work perfect for you. They are 850 gph, about 12x a 72 gallon tank.
For the Skimmer, I personally use a Berlin Classic. I wouldn't reccommend it, but it gets the job done. There is the
Marineland In-Sump Skimmer, I would use the 300. A lot of the guys on this forum are into the AquaC Models, and for a sump, I would think the
AquaC EV 180 would be a good fit. Or maybe the
Berlin X2 Turbo. This is the newer version of my skimmer, and a needle wheel, for better foam fractionization.
Hopefully this helped. What is your stocking list?
