i want to use a 5 galloncarboy
i have 3 gallons apple juice
will it be the wrong thing to do if i was to add 2 gallons of water to bring it up to 5 gallons
or should i just do a 3 gallon batch
Yes, if you have 3 gallons of juice make 3 gallons of cider, or buy more juice!
Yes, very wrong...
yes it will, just do a 3 gallon batch, otherwise you will have some really really light cider.

Secondary #2: empty
Bottled: Amber Ale, Hefeweizen, Apfelwein

don't water down a perfectly good cider... just use your 3 gallons, and preferrably get a smaller carboy... that's a lot of headspace for something to go wrong...
or like Yooper said, go get 2 more gallons of juice...
how much headroom should i have
But that's bad because it causes cidery off tastes.......ummmmm.
Yeh use sugar!
