I bought them from coralfanatics.com and it looks like they were under 250W and 400W metal halide radiums. I'm guessing that they have a large propagation tank setup so judging by most that I've seen, they probably were pretty close to the light. I did find that when I moved some reds that I bought from them up higher, they opened up better. But for some reason, I seem to think that the mean greens should be fine further down. Who knows...anyway, it's really frustrating because I probably only have 1/3 of the colony left from what you see in the pic in my first post of this thread. I did see a bunch of striped pods on the colony last night under the moonlights but as most people have said, they are just probably feeding on the already dying zoas. I'm running out of ideas and I may try to frag what's left to hopefully save a few zoas from whatever it is that is killing them. Argh!
