R/O water storage & TDS

remember reading on RC the same question awhile back. This isn't the thread I was looking for but similiar.

Either way sounds common to get a rise after storage.

Interesting. Kinda makes you wonder sometimes why we even bother buying a R/O unit. Heck, my tap water is 12ppm which is not bad considering the R/O water's TDS is only going to rise anyway. Huh!

I think the best benefit of the RO is to remove unwanted minerals and chemicals like chlorine, flouride and COPPER. If you put clean water IN and TDS rises slightly(remember this is ppm) when stored it is probably a benign bacteria growth eating something left behind from a water change. If the rubber maid plastic is soft, it is probably scratched and that is where the bacteria are finding their nutrients. The amount is SO small that they soon starve out and what you are detecting is their dead cells or whatever. Unless the TDS is REALLY high or the water has an "organic" smell(Phew!) I would not be concerned. T

This is just one theory for the mysterious rise in TDS with stored water.

Maybe the bin is leaching something into the water.

X2 you are probably better off with a food grade bucket try the wine store they sell food grade buckets.

Im going to go look for a food-safe container today or tomorrow: I was never really happy with the Rubbermaid anyway. The plastic is too thin and flimsy.

I am testing the recycle containers (The Big Blue and round one.) dont know how it turn out yet.
Any one tried it before? -pls let me know how is this material turn out. thanks.
I am planning to turn every related containers for aquarium to PlexiGlass. I still dont have a good feeling about plastic, even trying to test some.

Any other thought?

Thanks,
