My experience with ag lime was that it took months. In fact, full effect didn't occur for a year. But your mileage may differ, depending upon different soil & water conditions.
Interestingly, Calcis rep told me that they recommend adding 5 gallons per acre every year after the first large dose. Probably doesn't last as long as ag lime, if I had to guess.
I'm pretty sure it lasts a lot longer than lime dust, though. Very dense, twice that of water, so sinks to the bottom. Don't know what impact this may have on bedding fish...
