I have always grown daphnia outside, usually in an old fibreglass fish pond. I just filled it with water and then waited. Over the weeks, daphnia turn up from somewhere!
- Do water changes? NO but would have to top up due to evaporation.
- Do you use rain or chlorinated/dechlorinated water? Out of the tap but our supply is not chlorinated.
- Feed them regularly? Mine seemed to be doing well on Spirulina. NO
- Use an air stone or let the water stay stagnant? No airstone, it just sat in the sun.
- Cover the tank/container at all? NO
- Try to keep it cool during the summer? NO, in fact mine got very warm over summer months.
