Mr. Huntly I have been raising brine shrimp for over 30 years in a DARK 
room as almost all aquarium suppliers do, for they know as I do that brine 
shrimp need very little light, they need mostly heat! Yes brine shrimp 
will react to light by moving to it, but this is only to get the heat it 
normaly provides. This I have proven by setting up several tanks with both 
bright light sources and dim lght sources with the same amount of heat as 
the bright light tanks and there was NO DIFFERENCE in the development of 
the cultures! I asume your post was well meaning and as such I would 
suggest you go and read the literature and join the Brine-L list before 
making such remarks.
