TDS?

[Manoj's Reef]

Hi Jamie, my understanding is that when fresh RODI is created, it is an unstable state of water as the water is being stripped completly. Hence, to achieve a stable state it starts to absorb stuff from the air and you start to see a little bit of tds

I believe this is one of those inaccurate theories that gets cited a lot. If I recall correctly @AZDesertRat has posted on this very topic (possibly on a different forum).

My guess is that the food grade container is leaching something that's well... food grade.
