I'm not sure if I'll run a calcium reactor yet, at least not initially. I've heard so many horror stories (although, I think I've heard a horror story for everything now.)
I am concerned about recycling them though. Seeing as how I don't know what killed them, I'm worried that whatever killed them might be on the skeleton. I've heard about copper actually building into the coral skeletons themselves and killing stuff later (I have no reason to suspect copper poisoning...just an example.)
For the 150g, I'm going to have a crazy quarantine process. I'll do the usual dipping/breaking off the frag plug, etc. Then, it'll go into the 10g QT tank. After it sits in there for a month, it'll get moved to the 55g (I'm tearing it down and starting it back up with the 150g). Once it grows out a bit, a large frag will be moved into the 150g with a small back-up frag kept in the 55g. I'll dip between all tanks...and no bases will be transferred.
At work, we have to do "practice presentations" a lot since we brief so much. I usually brief on coral stuff, so I'm planning to bleach some of those skeletons to use as visual aids in my briefings. I think there's more educational benefit than aquarium benefit from them. My goal is to also put together a "newbie presentation" for the club...and use the skeletons as visuals there too.
