Not sure about the feather dusters, my Bariene Tang's got a weird appetite and has cleared mine out.
The shells I got at a craft shop(I think linens and thigns?), they had a Large bag for $4, about 3/4 where useful in the fishtank.
10K should work fine in a refugium, I was using old halide's for a while that where 10K and they worked fine. I use CFL's now, cheaper, they're daylight bulbs that shoudl be somewhere around 6500K.
