I usually add the pectic enzyme to a bit of water. Not sure it's necessary, mostly makes me feel like it will mix better that way--I can mix it in with the water then just drop it in, instead of powder just sitting at the top of my fermentor.
If you do that, make sure you use cold water, as hot water can neutralize the enzyme and it won't do anything.
How long did you wait before bottling? With the way the top is clear and the bottom is still cloudy, I would guess you bottled a bit too soon...a lot of that will fall out over time.
