Happy to help! Here are some links to the different pieces for the fuge:
http://www.amazon.com/Marina-Hang-On-Breeding-Box-Large/dp/B005QRDCP2 - for the actual refugium hob box
http://www.ebay.com/itm/Chaetomorph..._DefaultDomain_0&hash=item2a37c429b9#shpCntId - chaeto (don't forget to pick priority mail if the temps are freezing where you are)

Btw, I used a spare tetra 10i air pump and some airline tubing for the intake (which turns out to be pretty noisy), but now I just have a pump in the DT pumping water into the fuge without the noise of an air pump. You should be able to find a cheap fountain pump and airline tubing for pretty cheap at a hardware store.
Here's the link to another moonlight that seems to be exactly the same as the one I got, for around the same price. The one I got says it isn't available anymore, but it's exactly the same on as in this link

One more thing (sorry for so much writing!) You will need a light for the chaeto, which shouldn't be too hard to find. I'm using a cfl spiral bulb, but if you want something less bright I would recommend the tom perch light from amazon. Just in case you want that light, here's a link:

This whole setup currently supports a Kenya tree, four types of zoas, button polyps, pulsing pink xenia, a rhodactis mushroom, some green star polyps, a red elephant ear mushroom, and a neon green toadstool. I think all the corals combined cost $105 (not super expensive for that much coral
) Btw, I'll post a pic of the fuge in the morning when the lights are on.
