What would cause my pool water to have a brown film on it? How do I get rid of it?

I have algaecide and shocked it, the water seems clear except for a film on top. The filter doesn't filter it out and when I use my net it will bead up. If I am careful it will skim off if I gently let the net grab it. Can't figure it out and it's driving me nuts. Is it makeup maybe? There also seems to be some that has sunk to the bottom. I've tried vacuuming it but it doesn't seem like it's going out of the pool. Help me please
