I cant find info about the water to rinse it with other than "aged pre chilled water" What does that mean? Do we need dechlorinated water? Does the water used to rinse really have to be 40-50F?
It does need to be dechlorinated. The rinse water temp needs to be close to the temp the worms are being kept at to prevent temperature shock. Are you trying to culture them? Check out this thread: http://forum.nanfa.org/index.php?showtopic=3252&st=0. Skip to post 22 for the culturing info.
