Look for information on the AKA web site. http://www.aka.org/

You could be getting improved hatches for two reasons, using bleach to
clean hatching containers. The bleach could be helping to remove the
capsule of the cysts; or, you are sterilizing the containers, thus reducing
bacterial kills of your nauplii. I think that the latter is most likely in
your case. The pros always stress sterility in hatching artemia.

However, decapsulation does definitely improve hatching rates on cysts that
are not optimal.
