First non-turbo cider attempt

[fivegoldstars]

After umpteen turbo ciders and assorted varieties, I decided to make a non-turbo version this week.
A friend dropped me off four large carrier bags of assorted apples - crab, cookers and eaters - which I have juiced. The juice has been in demijohns for a day with a crushed campden tablet in each. I plan to treat them like turbos after 36 hours, except that I will not bother with the mug of strong tea, and I will use pectalose.
Question for anybody who has done this before - my juice has currently separated to a layer of fine sediment, the juice, and then a foam head (not a fermentation head). Should I pitch and ferment with all of this in place (obviously a vigorous shake to mix), or try and extract just the juice?

It was my first attempt this year at making Cider and I pressed my own and saw what you have described. I added nothing to the juice and let nature do her thing and I've ended up with lovely clear Cider. The juice from the press went into 2 litre milk containers first only cause I didn't have a spare fermentation vessel, as soon as I had I emptied all the containers into the one and left it there doing its thing. When it had stopped fermenting I transferred into a plastic brown 5 gallon keg and that's where it is now waiting until this time next year when I shall be sampling it..
