Hi there, If your goal is to make green water to feed the daphnia, you will be running out of green water quickly. Also, culturing green water becomes a task in itself. You're better off buying nutritional brewer's yeast, you need very little, a $13 bag of it will last you over year if not 2-3 years. I use about 2 tbsp/3 times a day to feed all daphnia cultures.
