Shock from things we don't measure being different in the new water? Or does old water hold magical powers?

My vote is shock and magical powers. The real magic though is that huge batch of new water mixed in with it. Nothing will ever look quite as awesome as with that first massive "water change" IMO. I always saw my LPS inflate, SPS with super extended PE, it was pretty wild (also that whole new tank look is pretty neat-o). I usually aimed for 40% old water but sometimes it was much less (like 20%) depending on how many extra tubs I had handy.
