Tournament Poker to NL Ring Games

[Eldog605]

Hi all,
I have a general question regarding the move from NL tournament poker, which i seem to do fairly well at, and ring game NL poker. Lately I've been pretty mediocre at the low limit online NL games.
I realize I am doing things differently in the ring games. I pick up less blinds on steals. I call more with middle pairs, instead of raising. And I seem to be playing more hands in general.
So I was wondering what the major differences are in tournament and ring game strategy. Thanks in advance.
