You can also help get rid of the film by laying a dry paper towel on the surface and lifting it gently back out. It will catch oils and such on top of the water.
When the regulator and needle valve are set, you shouldn't have to adjust anything for a steady output. When the tank starts to empty, the low-side pressure increases which will increase the co2 output. In stead of adjusting regulator or needle valve at that point it's best to get the tank refilled.
