How many units does it take to treat a 1 acre pond? I thought about treating mine when the pond is half full thus only needing 1/2 the material. If the water level doesn't stabilize till the pond is around 1/4 full then why treat the entire pond? I've read this is an all or nothing treatment for best results but that doesn't make sense to apply over the whole basin if the leak is in the bottom half.
