Hello all,

I know this is a dumb question but someone once told me there is no such thing as a dumb question.

Does RO water (unsalted) chemistry change over time? In other words, Is 4 week old RO water better or worse to use in water changes than RO fresh from the spigot? I think not but I'm finding my former chemistry classes lacking with this info.


Please forgive my ignorance on this!!!


Thanks,
