Picked up a Tunze Osmolator from a local reefer yesterday. It wasn't a huge important part (yet) but I had to jump on the deal. Rock purchase is next.
I've been going back and forth between man-made rock and BRS's pukani. I really like the structures that man-made rock can offer but you pay for that and you wind up with much less surface area. On the other hand, pukani has to be nuked/soaked and creating intresting structures requires some elbow.
In the long run, I think I'm going to be happier with some man-made rock and I've finally decided to go with Vidarock. Going to put my ducks aside for a few weeks and pick up a couple of centerpiece items. After that, it'll just be powerheads and light upgrades. I'm holding off on the lights until the very last so I can see what Reefbreeders unveils (referring to the Photon 48 and the Supernova units).
