Putting artemia in chlorine

Common practice at hatcheries is to put Artemia in pool chlorine to decapsulate them. This to disinfect the cysts and to increase hatching rate. Artemia use the energy of their yolk sac in the first 12 hours (thereby burning its nutricious value). So the faster artemia gets eaten, the more nutricious it is (I do not want to feed them).

Is it therefore a good idea to put unhatched disinfected decapsulated artemia straight into the display tank to let them hatch and eaten straight away?

Decapsulating artemia comes with health risks

Decapsulating artemia comes with health risks

I've read the instructions of decapsulating the eggs again, and conclude that it comes with serious health risks to do so. NaOH is one of the chemicals involved which bites through human tissue if not handled appropriately. The instructions also you to stir the container when the chemical reaction is running. I doubt that breathing the produced gasses is also safe.
I therefore have abandoned the plan.
I am curious if somebody can share his/her opinion on this practice.

I honestly did not want to go throught that procedure myself. I, like you, wanted the advantages of the decapsulated eggs. I but mine already decapsulated from Brine Shrimp Direct.
 
They recommend putting an alkaline (NaOH) to the liquid bleach to make the pH to be > 10.

SWINGRRRR, have you used only bleach to decapsulate them? I'm curious to know the hatch you got.
 
I used bleach to decapsulate them in the past but I was never able to get them to hatch.

I have done it in the past, but none hatched. It was my fault though. I found some 2 year old eggs in my garage and decided to play with them. I de-caped them and waited, and waited. Nothing happened, but the general consensus was that after 2 summers and winters in a FL garage, the eggs were toast. I just threw them in the tank for food.
