Hello everyone. Have a 1.5acre old (at least 70yrs)sand pit in nebraska. Main portion is 12-14ft deep. Over half of the edges are covered in cattails. I know there are carp unfortunately. My question is, most pits around here are pretty darn clear water but not this one. I'm just guessing its' from years of leaves, cattails decay, and carp. I'd guess the visibility is about 12-18in. Any suggestions on what may be causing it or anything to help it? Or is 12-18in fine? Drives me nuts as most other pits are clear as a bell around here and I like clear water.
