I'm very curious about this as well. I have just set up a Marineland Eclipse System 6 in a co-workers office and am trying this method.

Actually, I wonder if slowly filling it up via daily misting with a hand sprayer isn't a bad way to go about it. It'll keep the humidity levels up, and opening the top to do this will also allow some air exchange (not sure how important that is, but I would think it to be beneficial). After nearly 1 week since setting it up, there's approximately 0.5in of water above the lowest level of substrate (which is angled back to front, not flat).

I wonder if spraying a weak nutrient solution to be beneficial as well? Would mixing KNO3 and KH2PO4 in one sprayer, and CSM+B in another and rotating them each day be of some benefit? Sort of a "pseudo-EI" misting?
