Algaecide in the water your pool shop will give you the right stuff I like copper based algaecide, and scrub the walls of the pool with a stiff pool wall scrubber on a long handle. you will find that a lot of the stuff will die and end up on the bottom after a day or so, Hand vac back wash and scrub the sides again. If that doesn't start to improve things you may have to use a floculent and then vacuum the algae to waste. Just ask your pool shop about it and the will set you on the right path.
