I am so glad I found this site. They told me earlier today that my CY level was 90. Now I know that seem high however the way that they tested it was by putting my water in a little tube and lifting this rod until you see a little black ball. Now i saw them test it and the bube had marks on the side that had the 25 mark 50 mark and 100 mark. So how they came up with 90 is in my opion is only a guess.

Is that the same way you test it with bens?
