One more question, once I get my culture going how is it sustained? Do you just add new water to replace what is used? How long will a culture last?
I’ve kept cultures going for several years.
I would replace the water removed from this culture with tank water from fry grow-out tanks during water changes. It always seemed to have enough nutrient to feed the culture well and keep the water nice and green. I had lots of daphnia back when I had this culture going and used to pull off 2 gallons a day just to feed the daphnia.
