It does sound like the algaecide you used had copper in it and that the subsequent shocking raised the pH that then colored the water green, though now your FC and pH are down. Your CYA level is high which means it will take a higher FC to get rid of algae, but assuming that the green is solely from copper you can 1) lower the pH and see if it lightens up and 2) use a metal sequestrant.
Depending on how much copper you added, you could have a difficult problem to clear up, but the sequestrant and clarifier are ways to get there. I just hope you don't get significant staining -- at least with a vinyl pool that's less likely -- if you had a plaster pool, well, it could be a lot worse.
In the future to control algae I suggest you read the Pool School
to learn how to properly maintain your pool and the FC/CYA ratio to maintain.
