I watched..still not sure why the original reef was torn apart. We all know..those pests will return from new rocks added. More or less. it was one of the nicest reefs on the planet- only those reefs done outdoors in tropical climates were more real. Now,what do I think? I think the owner just got tired of incremental changes year after year. Impatience set in and the desire for the excitement of a new Christmas in summer feeling. My plant tank is going on 4 years now. I think to myself if I would just go with pruning or one day say I want a new and better ecosystem? So,I am not apart from everybody else and "newitis".
