Welcome, and congrats. There are a lot of pro's for the Tunze 9004 skimmer, over the ghost skimmer. I'm going with the ghost for more flexablity. Plus the Mini Max reactor (GFO) If you go this route make sure who you are buying tank from gets you and IM preformace pack. Check it out at IM or MD. I'm going with AI 26 light. Again there are a lot of various opinions about this one as well. For me it was cost and controls. Also I'm converting first chamber to refug, using custom caddy and IM mag led light. Plus I really like the IM ato tank. I will be getting one of the new APS stands. Hope this helps, its a lot to take in, but review a lot of past post form others. Also a lot feel that the return pump is junk, some are replacing that too. Since I'm like you own tank and above gear, just waiting for stand to arrive at WS.
Can't wait to hear you process and what you end up with..
