Bryan, cant help ya with the fish and I am no expert on ponds. But I dont live far from you (Batson) and have been working on a similar problem with my pond and mud. You can search the back posts on muddy water and get alot of good info. To start get a glass jug (gallon) of pond water and let it set for a week or so. If it doesnt clear then add lime or gypsum. I used gypsum and started with 1/8 teaspoon and waited for it to clear. Then calculated how much to put in my pond. The next question will be how to apply it. More dicussions on this subject can be found here. Good luck and check back with your updates. JIM
