View Full Version : TDS of storage containers

Hi Guys,

Finally setup my Spectrapure 90g RO/DI since I was tired of lugging 5g containers from the LFS. lol

So here's my problem.
RO/DI coming straight out of the unit is 0 tds when measured from a small bowl.
I have 1 5g jug that I'm getting 0 tds from.
I have another 5g jug that I'm getting 34 tds from.
I have a 30g white food grade container that I'm getting 4 tds from.

I've washed all these with vinegar and bleach so I don't know what's going on, especially from the 5g jug with 34 tds.
The 5g jug I can throw away eventually but what about the 4 tds from the 30g container that the RO/DI unit will run to.
Should I be concerned?

They are still contaminated, and need to be rinsed well with DI water. I stick my tube at the bottom of the reservoir, and I let it overflow outside when it is new to wash the contaminates out.
