I just went out and got a sample of water, nobody has been in today. I could see thru the water in a bottle. The water is not muddy until somebody goes in. I went back out with a flashlight and I guess I could see down about 6-10". No fish or live stock, also hardly any grass around the pond. I have also put aqua blue in it and it turned the water a nice shade of blue green, that was about two months ago. Its not as blue now. I have no aeration systen yet either and have noticed a muddy like sludge that some of it floats, I can also pick it up and throw out. thanks for getting back to me so soon. I am new at this pond thing and just want it to be a nice place for my family to enjoy
