I have a 1.5 acre pond in Texas, In the summer it receives a ring of vegetation about five feet out or so, and did I mention it is clear,! The vegetation creates only a ring because the pond goes deep in the middle, around 15 feet. The pond has , numerous hand size greensunfish And I recently stocked it 2 years ago with 9" bass, and they have spawned, and grown just a liile. I`m thinking of adding BG and crawfish,to supply a good supper! or fertilize. However I`m afraid of fertilizing because I fear the cost,THE CORRECT PROCEDURE, AND THE MESS UP? OOOOPS! Any knowlegeable advice sure is helpful!!!!
