OK, so my post has gone unanswered, but I won't be deterred. I'll take this lull as an opportunity to add some pertinent information. Here is a photo of the same jar of water to which I added about 1/4 teaspoon of alum (from the spice section of the grocery store). I stirred it in and allowed it to settle for 20 hours.
The before and after photos are dramatic. Now that I know alum does the trick, does this mean I have to use it to clear our new pond? Will the eventual growth of weeds, or some other natural process clear the pond too? Again, any help is most appreciated.
