Well, after becoming fed up with the sheer number of Aiptasia I had infesting my system, I became bold and tore everything apart. I purchased all new, dry sand, mud, and live sand from various sources. All the infested sand, rock, and (sadly) seagrass is gone. I was able to save 2 sprigs--one of each species of seagrass. I'm in the middle of receiving more types of live sand from various sources, as well as boosting my seagrass population. As of now, I've got more shoal grass (Halodule) coming and I'm going to attempt some turtle grass (Thalassia). The new setup features deeper, finer sand. There will be no rock for now, though I may add a piece of dry rock later. The few corals I still have are covered in Aiptasia, so they've been relegated to a quarantine setup lit by some spiral compact fluorescents in order to be de-Aiptasia'd with some Aeolidinella ("Berghia") nudibranchs. Hopefully, the new setup will be successful and the corals will be denuded of Aiptasia. I still plan to feed heavily, which is why it is vitally important to not have any Aiptasia, since even one could explode into hundreds with the kind of feeding schedule I typically use.
Anyway, some pics:
