"Another question, who has used entirely dead/base rock for their reef and then seeded? How did you seed? How did you light until established? Did you run your protein skimmer while seeding? That kind of stuff."
Sambo-
I have used only seeds and if I ever started from scratch again I would do the same. A fair number of things I'd do different now, but that part would remain the same.
I started the seed tank when I began making the rock, by the time the rock was cured the seeds were about as "clean" as they were likely to get.
Upon verification that all was functioning in the tank the seeds went in. Skimmer running, all pumps going, lights at regular intensity and interval, etc.
