Hi pshaw730. It depends on the temperature of the room where you are fermenting the juice. Can take two or three days to ferment dry or can take several weeks. Will it clear? Possibly, but you might want to add pectic enzyme before you pitch the yeast. Even without the enzyme it can still clear but it can take several weeks.
When you ask when you can put in another bottle - do you mean how long before you can add another bottle of the juice to the cider or how long will it take before you can bottle what you have made? If the first question, you can add more AJ today. If the second question you may want to wait until the cider has fully fermented (a gravity below 1.000). With Mott's AJ you may want to add some acid blend to help give it a better kick and perhaps some tannin
