Pond Boss Forums FISH & FISHING Sunfish-Including Largemouth and Smallmouth Bass Fungus infection on fish

My thought is that if the ground or surface water rose to a level it has never been or has rarely been at, it could have hit something that was otherwise stable which was then set free by the high water then pulled into your body of water and possibly changed the chemistry. I'm obviously not familiar with your geography, but I wouldn't trust the assumption that the water in your BOW includes only the runoff from 5 acres. Do you have water samples from the past that could be compared to current samples? Adjusting PH is relatively easy to do.
