water for water changes? (a little off topic)

[Rudiger]

Hi. I found a source for RO water and Im going to bring it home in plastic gallon jugs (like you buy milk in...). To get the jugs I went to the store and bought 3 gallons of pure distilled water, no added sodium or anything. This store bought water is also okay for water changes, right?

ooo, just found out from the other forums here that store bought distilled water can have traces of copper, since the disstilling machines often have copper pipes. Another question though, I have learned that octopus blood is based off coper, while ours is based on iron. Its good for us to have iron in our diet, so why is copper deadly to an octopus (and many inverts as well) ?
