To state it simply, I don't have a clue
Nice Joey, that was good for a laugh!
I don't think the muck can be all that thick as the pond was renovated in late 2017, but I don't go to the bottom much. The sediments are probably a few inches thick as the aerator bases seem to be hard to pull up off the bottom, but sediments and muck, in my book, are two different things.
