Rock Anemone: Thanks for the kind words and I'm pleased you have enjoyed the ride too.
Marc: Definitely, the tank has filled in greatly but there is in fact "some" space remaining for the fish to swim.

Unfortunately, the photo has a 2-dimensional look that flattens everything out. For instance, the whole left side section is actually an upward sloping wall with relatively large amounts of open water space in front. The right side is another story though.

Here, it's pretty much filled in except for the channel where the corals haven't been able to grow due to the high flow from the Penductor. You can see this if you look close. Maybe that's the "coral growth inhibiting" action needed. Just blast high flow right above them all and they will stop going surface bound.
Detritivore: I hear you but I really don't think that's going to happen anytime soon.
Jonathan: ... And the Green (yellow) Slimer at the right too.
wonrib00: Read back a few pages. Unfortunately, it didn't survive.
Lee: As mentioned above, it's not quite as "a wall" as it appears in the photos but it's getting close. The channel between the two formations is basically a small tunnel now that the Tangs just make it through. It dose widen towards the back though. Unfortunately, a photo wouldn't show much except the Miami Orchid in the front and the blue/purple Stags behind. But... here's a better center section shot that I must say is my favorite part of the tank. Aside from the PVC returns above, I feel it most replicates corals in the wild.
I can sell frag packs for $200. !?!?!?

I have and do give out frags (locally) but always try and pull for areas that don't disturb the look of colony corals. This is what I've strived for, look wise, so...
As far as future equipment builds, I've been considering converting my dual Beckett skimmer to a recirculating, needle wheel but only as a means of saving some energy. I'm still in the thinking stage of this so it won't be any time soon.
Robbie: Thank you very much for the kind words and you are very welcome.
m1enbo1: Thank you.
Joseph.
