Does anyone here use 7th generation powder detergent? What do you recommend?
I did not have good luck with the 7th gen liquid on my pocket dipes -- they were leaking badly -- but haven't tried the powder. I think the enzymes they put in there are bad news for diapers. We had bad ammonia smell with soap nuts, and repelling/leaking with most name-brand detergents. We've had the best luck with generic store-brand free & clear detergent, honestly.
There's a pretty good chart of recommended detergents here: http://www.diaperjungle.com/detergent-chart.html
