I think lime trucks like in the picture above will usually deliver 4 to 6 tons. I have had them disperse half of it in and around the pond and then had them empty the truck into a mound where I could go back with the front end loader on the tractor when I needed to add more lime. How much really depends on how well it is spread around the pond and where it is spread. Windy shoreline do better than a protected shoreline.
