The last time I did a jar test, couple months ago, I found what looked to be some dead or decaying material floating in the test water. Have not check it this time. I have a bottle of pond water that has been in my truck for a few days and the water has a green tent to it. When checking the visibility in the pond I can only see about 8 to 10". I put the water in a bottle and the water looks pretty clear with a green tented color but looks like I should see a much greater distance because it's not all that green and it's not dirty water or cloudy. I was thinking if it was the sun screen I might see a reduced number of microscopic plants and animals. But now I am thinking it would need to be looked at before and after. Or if it was sunscreen dye would there be no plants or animals in the sample? That is what I was thinking when asking Mr Cody.
