I followed directions on the bottle by adding 1/2 teaspoon of powder per gallon to two five gallon batches of very cloudy cider - one after fermentation as I racked it into a secondary carboy and another five gallon batch that I was starting in primary.
How long do you think it will be until the cider is more or less clear?
