Im not sure how long I waited maybe a week and nothing seemed to be falling to the bottom. Should I do another test. I added the alum to one of them and just started playing with how much it took. I ended up adding somewhere like 20 grains of alum to clear it up within mintues. They get gin clear in bout 10. And yes I mean 20 grains im not sure I can even measure that. I might try this on a bigger scale (for test purposes). My next question is where do you buy the alum and lime in bulk? The farm store here looked at me like I was crazy.
