+1 on the clearing. It seems like it should be more clear than that by now. Did you use anything besides honey? If you've added any type of fruit, you'll probably want to throw a bit of pectic enzyme in there, if not, then I'm not sure why it's not clearer. I like the marbles idea, but that is a lot of space to fill with marbles. If you try it, be cautious about moving it after you've added them. If you move those marbles, it will stir up the stuff on the bottom pretty quickly. I would be tempted to buy a 3 gallon carboy and a 1 gallon jug, and split the batch. If you have to rack again, which you most assuredly will, you'll have the 1 gallon to continuously top off with. Bonus, it will give you an additional empty carboy to fill.
