I'll assume you mean "rinsed" off all of the soap....and made sure there was no residue under and in the corners of your nails etc... Honestly I am pretty paranoid about soaps and tanks as like
@Salty Cracker said even trace contamination can do serious harm to a large system. I avoid working in my tanks if I have used soap recently and if I plan on working in the tank I avoid contact with chemicals and wash with just water beforehand. If I have recently used soap or washed dishes etc and suddenly have to put my hands in the tank then I put on some gloves.
Regarding other questions...many of us have pulled a bunch of corals out chopped them up into frags and glued a pile of things all at once with no issues other than a crazy skimmer for a bit...so I would look elsewhere for the culprit. Some carbon or Poly Filter pads (that's a product not just filter floss) will pull metals or organic contaminants out.
If a WC was the cause then doing another may make it worse...if the issue is with your source water, your container or your salt (just opened a new pack of bad salt? Salt left unsealed near soaps or cleaners will absorb contaminants easily...)
Before you potentially add more contamination make sure you have eliminated those items as potential sources...
