1) There is hardly any muck in the area where the water has dropped. There may be a foot or so where the water is now, not much.
2) I am worried about that as well. I think my only other option is to have a deeper well drilled. However, I don't have the money to do.
3) My main goal is to just have a place to fish and be able to catch some decent fish in the end run. Would like to see some monster sized, CC, BG & LMB after time. I do plan to feed them as well.
I'm not sure if I would gain anything or not, and I'm not sure how to find out that option other than by trying it.
