Tried to find this out in a different location..
I'm about 4 weeks into my first batch of 2+ gallons. Used half filtered and half unfiltered AJ/C. Didn't know about measuring pH with cider and didn't add nutrients. Later found this yeast (M2) loves nutrients. On racking a week ago, the SG was 10.. down from 60. It's very cloudy.. same as when I pitched.
Also didn't know about Pectic Enzyme. So.. aside from that first paragraph.. Is it too late to pitch PE? I'd like mine to clarify.. at least somewhat. What about fining with gelatin? That works with beer.. but, I'd bet that what clouds the cider is different what clouds beer??
