Bassman - I just finished a experiment on water clarity. Using two jars and a silver dollar size piece of half inch drywall. I filled both jars with pond water, floated the dry wall on top of one of the jars, left the second jar with just the pond water. The drywall sunk to the bottom after about 45min. I then left it in the jar for about four weeks, shaking both jars once a day to represent any movement that may occur in the pond. After four weeks there was no visible difference in the water clarity that I could see between the two jars. The drywall was still intact, but only the size of a half dollar.I can't tell you when the drywall finally dissolved, because my wife got tired of looking at the jars on HER deck and dumped them out.
