Wow,
Get out a biology book. Osmosis is the transport of salts and other ions across a membrane. Ions, especially salts, will always move from the higher concentration to the lower concentration. I think the guys are correct in suggesting there is an
ulterior motive for suggesting softened instead of DI.
PS. Put a tree frog in DI for a day and watch him shrink. Just Kidding, I wouldn't want you to do that to the poor frog.
