Hi Dave,
I believe your baby Trochus snails will do just great in the CPR. They'd also probably be just fine in your sump and would definitely do just fine in the main tank.
Like you, I'm a little surprized that they're in your skimmer
and can't really imagine them surviving too long in there, but hey, they've made it this far right?
If you don't break it down and pull 'em out, you can let us know how long it is that they can actually handle that kinda treatment.
As far as what you could do to promote their well being, I'd say that (except for the ones in the skimmer) they'll do just fine on their own. According to Dr. Ron, a lot is still unknown in regards to their specific diet so *I* certainly couldn't tell you precisely what they eat. As I said, I think if they've made it this far, they're finding enough food and should do just fine. Here's an interesting link to an article from Dr. Ron over on AQFM:

Other than that, I'd say if you really want to track down more info on the "procedures" for captively breeding/raising these snails, you might want to send a nice inquiry to somebody who is doing just that, like IPSF. Maybe they could shed some more light on the situation, but I imagine they're doing just about what you are, simply on a larger scale.
Whenever you get ready to let go of some of your babies, I'm sure you won't have to look any farther than this board to find lot's of willing adoptive parents!
Regards,
Steve
ps-no need to worry about the bristle

A couple in my one overflow and 2 in my skimmer of all places. They are no bigger than specs, but are absolutely tiger trouchs with the marron striped shells
