NSF food grade typically means low porosity with low leaching of chemicals.The low porosity is for sanitization reasons under the impression the holding vessel or tubing will undergo chemical or heat treatment and will not degrade and can show acceptable levels of pathogen,or organic bio- film reduction.If your holding tank is exposed to unflitered air,you will get something growing.

Hey Greg, have you ever tried cleaning out both barrels to narrow down where the film is coming from ?
Maybe it's the barrel itself ??? Fill the second unit from the first with a jug or something to rule out the hose and pump setup
