Bleach Ratio for Decapsulating Artemia?

[fishydaddy]

I'm going to try decapsulating artemia cysts for the first time and I am seeing so much conflicting information on tutorials, especially when it comes to the amount of bleach used. Some say use straight 5% bleach, and others say 2cups water to 2/3cup bleach, 1:1 water to bleach, 1:2 water to bleach, etc...
Does it matter much what the concentration is? I am assuming the concentration just changes the amount of time it takes to remove the shell. In y'all's experience, what has worked best for you?
