Chris,
the words are kind but I know it's not that great. It's usually "fuller" with Halimeda but I've been hand-harvesting all the Halimeda I see to try and give the Uddotea and Penicillus a chance to get established. The Halodule seagrass just holds its ground but the Syringodium does well. Most of the visible algae colonies on the rock collapsed after the high flow vegetative filter got plumbed and I began persistently running the skimmer. This has left the rock rather bare for my taste but at least free from Derbesia and similar pests. As far as coral, I'm experimenting with those I think are found - at least occasionally - in back-reef areas to see how they respond to my husbandry. In a later tank I'd like to have a large expanse of grassbed, with just a few corals selected from the current ones clustered in a single location near the bottom. Then they can have years to grow and establish a natural looking bomme, instead of this menagerie stuck here and there. But I'm still learning the basics and this tank has been a good experiment.
As far as abandoning the skimmer and GAC now that the scrubber is up, I don't think so. I also do large exchanges of water (50%) quarterly using local NSW, which is another large departure from what Adey recommends (and just about everyone else). I've arrived at the conclusion that its better to form my own goals and try to evolve the husbandry to reach them rather than to emulate someone else. Not that I am knocking, in any way, anyone who wants to operate a more (or less) "natural" tank.
