What is the white film? Are you using distilled water or tap water?

Rge as he said is plasticizer...

it comes from the tubing.

Any cheap tubing will have plasticizer leech in it.
Its what makes the tubing soft and highly bendable.

The more expensive tubing uses something else, so you dont get tubing clouding as fast as the cheap tubing.

Typically u wont see clouding on tubing until u go at least 3 months... less if u constantly drain and refill.
