Not sure about how "reef safe" if it all any chemicals are, except for additives. What lights are you running it under? What is your salinity? Have you verified that it tests accurately? What are your levels? How large of water changes did you do? What livestock do you currently have and how long has your tank been running for? It is also important that if you do the lights out bit, that you bring your lights on for a shorter time when you start to turn them all back on.

It could just be that they will come out tomorrow, but posting any info you can in the interim would help in concentration on a resolution.
