HI. I went and did what you had told me, and, you cant see but 6 - 9 inches int he deepest part of the pond, yet in the shallow end, you can almost see the bottom......I wonder if there is anything to do to get the die out of there...also, would putting aerators int he pond help in this case..even in the long term if (when) things start dying...I hate the feed store guy told me to put the die in there.....
