Re: [Live-foods] Daphnia


That's interesting.  So the daphnia "shells" are mainly protein!  There goes
another illusion!

Much of the daphnia culturing information of the web suggests hard, alkaline
water, although Dr. Masters' "Encyclopedia of Live foods" does not mention
water hardness in daphnia culture.  (He does say that a neutral or higher pH
is preferable.)

It might be that some populations of daphnia have adjusted to vastly
different kinds of water.  

It also might be that the organisms on which daphnia feed grow better in
harder water.

If you had your druthers, would you use hard or soft water for a new
culture, or would it make no difference to you?

Thanks for this information!
