Re: Daphnia water changes



Well of course you can split old daphnia cultures and start new ones, but eventually you will run out of tanks, or galaxies to put the tanks in.  I change about 20% a day and feed the daphnia I suck out with the "bath water". Read Jim Langhammer's article on the killifish site about how he does it.
