I split these out from the stickied thread, since they will get more attention as a separate thread instoed of buried within the previous topic. Not sure why it still shows the previous page count and originator--my apologies!
UV lighting is not the same as 50/50. UV refers to a specific light spectrum. Many bulbs will provide a small amount of UV light. The 50/50 bulbs are 50% "normal" spectrum and 50% actinic light--not the same at all, and not for use in a UV sterilizer.
Cycling with uncured live rock does not require the addition of a shrimp, but I would treat it as fish cycling and do frequent water changes to prevent dramatic spikes. As wtih fish, many organisms on the live rock will be damaged by exposure to high levels of ammonia/nitrites.
