I've never had any luck with daphnia in containers any smaller than 150
gallon kiddy swimming pools in my back yard. An active culture of dapnia seems to
depress mosquito larvae for some reason. I start out with a leaf of hay from a
hay bale, I weight it down in the middle of the pool add a little bit of
miracle grow and a small amount (gallon) of mushroom compost. I let it set until it
turns green and them add daphnia, about a tablespoon of them. In about two
weeks I can harvest all the daphnia I want.
