I know the feeling, I've done that by moving things around�� If you are able to do a water change that might help, but just letting the filter work its magic is what will do it. Did you rinse your substrate at all first? If you didn't and you'll be adding more in the future, it just helps lower a bit of the 'dust' but I still seem to have it happen.
Everyone seemed to survive in mine, but I was able to crank up my canister filter to get rid of it quickly...if you don't have this ability then yea, I'd say water change maybe before putting anyone back in?
