Thanks for giving a lot of information. But, I do have some more questions for you.

What kind of algaecide did you use? A lot of those can make a mess of the water. What kind of chlorine did you add and what are the ingredients of the shock that you added? Is the water still green? What size is your pump and filter? Is this an inground or AG pool? Vinyl or gunite?

Do yourself a favor and order a good test kit instead of having to rely on the pool store. (Often their testing is not very accurate.) We recommend the Taylor K-2006 or 2006C that you can get through the test kit link in my signature below.
