Tyrone,
   You should put a quart jar of water in the sun for a few days until 
you have green water and then feed the daphnia from the green 
water.  Donot put the daphnia into the green water, but put the 
green water into the daphnia container.  This works fine.

Why use live yeast? Why not used the powder form 
avaiable in shops (brewer's yeast).

Alternatively, why not try other powder foods. I think 
the Mike Reed NO-BS fry food (fine) is good enough to 
feed the the daphnia. I think it would give them 
superior food quality too.

Alternatively, setup an indoor green water culture. Set 
it up and give it regular fertilizer (hydroponic, should 
be available at nurseries) and then give the culture 
some sugar (5% max mass:volume i.e.: 5 g to 100 ml H2O). 
This would supply the carbon needed for bacteri/yeast 
growth as well as the carbon dioxide for the green water.

I hope this helps some what.
