I know. Sometimes when printing my pics to paper, the colors aren't always right. But in this case, the color is spot on. Thats why when I saw the first patch of it, I thought it was trash - it really looks just like green string. When I grab/pinch it, it just dissolves where I touch it.

I was thinking that maybe my water was too clear and that the bad algae was growing, but I don't know yet if that is the case. I haven't tried my disc today, but I doubt that visibility is more than 12 inches...
