Yes green is very normal. It will vary from
tea/coffee colored to green colored. The green is
from algae. If you look at it under a microscope you
will see bits of algae, and also single cell algae.

Well, it actually started producing today. Its not as much foam as I see
other skimmers producing, but it is getting a little stuff out. Alot of
people I have seen say the waste should be brownish, but mine is green.

This sound about right?
