That sounds like a really cool fish for the reef. Where can I get one

True but maybe not true too You have to also look at the levels of things like chloroform in the water. Simply having some present is not necessarily dangerous. You have to ask how much is there in the water? How much is then absorbed by your digestive tract? How much is then inactivated by first pass metabolism in your liver? How quickly is it excreted by your kidneys? And of course how much was required to give rats cancer? Cholorform is fairly volatile too so if you use a Brita for example and then have the water sitting in the Brita in the fridge a good portion of any chloroform would probably evaporate out of the water. Toxicology is complicated and you can't simply say there is some chloroform in our drinking water and it will cause cancer.

Drinking tap or filtered water, does not have any direct impact on your mineral/vitamin uptake unless you are drinking good "mineral water". Even then intake is minimal, plus most people do not use mineral waters as any kind of significant nutrient uptake anyways. So drinking really pure water would only have an effect on your body at the excessive side of the scale. Pure water will make water intoxication, or Hyponatremia develop faster.

P.S.
RO/DI coffee IMO tastes way better.
and i'm not sure on this, but in my mind since your drinking water is also powering your bodies waste filtering systems that the purest water will help it work better. I.E. ~1 TDS can absorb more toxins then +100 TDS water.

I still think you would have to drink a heck of alot of RO/DI water to suffer water intoxication. As for helping your bodies waste filtering I have to say probably not. Once the water is absorbed it goes into your blood where it basically mixes with all the minerals /proteins etc. in your blood anyhow. It is the blood that is then filtered by liver and kidneys etc. Drinking RO/DI water will not affect your blood chemistry or composition so would not have any effect on your bodies ability to remove waste or toxins.
