If your fish have developed Ick I wouldn't put them back into the tank. Set up a hopsital tank so you can treat them with hyposalinty or copper if need be.

Watch your LPS, if they are doing ok then I wouldn't worry about your softies. If your shrimp are doing ok then we're looking better.

Your bristle worms are a good indicator that something is definately wrong though. Did something die in the tank recently, before your first fish, like a coral perhaps? What is the popluation of your bristle worms? Sometimes they reach a critical population and start inter and intra specific warefair with themselves and other creatures. This can ultimately cause a NO3 spike because of all of the death. I've also seen a die off of worms and snails caused by ALK and PH spikes.

Check you electical as well to make sure there are no shorts etc.

I think the most important thing to do though, is not panic. Slow down and really anylize your situation, don't do anything too drastically, that could make things worse.

So you have a sandbed?
