How much Ag.lime per accre or gal. of water? I do not have the means to evenly spread it through out the pond. I will have to broadcast from the shore perimeter, that's the best I could do right now, I don't have a small boat and have only a week before I have to leave for about a month, won't be here to monitor any actions I might take. Maybe the safest is to do nothing till I get back?
