What type of fluid did you use in the PS pump?

I thought slow pedal return indicated air in the PS system.

I just used regular ATF. I read that some people said that you cant get all of the air out of ATF. I did check with it running and inside the P/S pump it didnt look foamy or anything. Maybe I should change out that fluid for Royal Purple Power steering fluid or something to check if thats it.
