Also note, you don't want to just pour the beer from the primary to the secondary, you want to rack or siphon it... and you want to avoid splashing, sloshing or any other agitation that would cause oxygen or air to get into your beer. Aeriating your beer at this point will cause off flavours.
I usually leave my beers in the primary for a week. Sometimes I've left them in the primary for two weeks. My beers usually get two weeks in the secondary fermenter and they are pretty dad-gum clear.
After a year of sitting idle, Andre's All-Grain Brewery has reopened.
