Try usein Shock powder. Shock is concentrated, usually unstabilized chlorine. It's used in a pool to quickly get the chlorine residual up to hammer organics ( like the ';greasy film or green'; you have). Normally, if you're pool is clear, you use it once a week. If it's cloudy or green, you double or even triple your weekly dose depending on how bad the water clarity is. Shock, being unstabilized, goes to work fast but also gets knocked out of the pool quickly because it has no defense against ultra violet rays from the sun.I have a 14' x 28' in-ground vinyl liner pool.

You need to take a soft nylon brush and scrub the liner. This is bacteria or algae building up on it and can be removed.
