Bummer about the big tank-crash, but mad props on the re-boot. Strange about the bio pellets causing an outbreak like that, but not unheard of. Miracle Mud can have the same effect on a mature system. It's against many companies recommendations to do so. I've told several reefers about following the directions, but they just hate on the products instead.
Your new corals are beautiful. Even though you say they haven't colored up they are still remarkable. I love to see tanks where people have pushed the established boundaries on what fish and corals can successfully be kept. On that subject, have you seen Ching Chai's NPS tank. He has a small tank separate from the large DT where he can keep very sensitive filter-feeders. Once a day he just isolates it from the system and dumps in a huge amount of food for the corals. The corals get to pig out for an hour, and then he turns a valve and the huge amount of food gets quickly diluted in his system's vast water volume.
We're looking forward to seeing your tank mature with these wonderful specimens.
Could you shoot a video of your tank. Nothing special. Just five minutes or so panning back and forth. Your pics are excellent, and I would really look forward to adding another great video to my Youtube fav's.
