Russ and Jeff --
Many thanks for the input and suggestions. I'm really intrigued by those storm wattles and want to see if I can get some locally to try them out.
Visibility increased somewhat in the pond today. It's now almost 8". An improvement, but still not what I'm used to.
I tried my first limited application of aluminum sulfate today. I mixed in almost 8 pounds and distributed it as evenly as possible around the pond (canoes sure weren't designed for tasks like this!).
So, I'll start researching storm wattles ... and wait and see how the aluminum sulfate works over the next couple of days. Many thanks, once again. -- Mike
