Time and Cold are the two things that work best for me.
Also, when you transfer always try to leave stuff behind - kettle to fermenter, primary to secondary, secondary to bottling bucket, bottling bucket to keg/bottle. At each stage, stuff settles out - try not to stir it all up and end up moving it along to next vessel.
If you moved it after a week of primary, it definitely would be cloudy. Generally, I just go 3 weeks in primary with no secondary. As fermentation winds down, most things clouding the beer settle out. Some people do a couple days of cold crashing after their 3 weeks of fermenting to help drop more out of suspension. Also, beer tends to really clear up after carbonation and as it sits.
