water for daphnia cultures
I am on city water and do not have easy access to well water or spring water.

pond and they did great until summer heat crashed the culture. The only
thing I added was a few chunks of whole limestone and assorted whole FW and
So what are folks on city water using to culture daphnia? Rainwater? Old
aquarium water treated with something other than "Amquel"? Purchased bottles
of spring water? Any other options?
