decapsulating brine shrimp eggs

[Brown_D at kids_wustl.edu]

My brine shrimp hatching is not yet optimal, and I am considering
decapsulating them before hatching.  The standard protocols include bleach
and sodium hydroxide:  where do you get the sodium hydroxide?  Is there any
common source of lye that is pure enough to use, or do you get it from
pharmacies or chemical supply houses?  I can use a small amount from my lab
to do a trial batch, but that's not a good solution for the long term if I
decide that's how I want to prepare them routinely.
