TDS
Tap water = 105
Water before DI pod = 2
Water from RO outlet = 0
Water in storage container = 94 !  :S

The tank will be fine, it's almost impossible to store water and it stay at zero.

Don't forget RODI unit will strip oxygen and other gasses from the water, but oxygen and other gasses then redissolve into the water, giving a TDS reading again.

So does that mean it's pointless trying to store it?

No, because it's had all the bad stuff removed. What you're storing is pure water, that's re oxygenated, and that's a good thing. Put a freshwater fish into RO water and watch it die quicker than it would out of water...

If you put an airstone in it, it'd reach that TDS sooner.

So with that in mind is it best without the airtight lid fitted to reoxygenate it or should I fit the lid to keep it?

I store 300L at a time in water butts in the back garden I've had no issues but then it does get turned over often

It'd be ok with the lid, it won't go stagnant as there's no life in it, bacteria etc. If you take the lid off, then it would eventually so I'd put an air stone in it to keep it fresh. I'd probably prefer an air stone, but it's not a big deal, just like to keep water moving.
