You know - i have a filter system attached to my tap that makes water higher quality than that stuff - 75 gallons per day of 100% PURE H20 -- not a single contaiminant - NOTHING
5 Stage RO/DI - Polyfilter -> 5 micro carbon block -> 1 micron carbon block -> Reverse Osmosis unit -> De-ionization unit
I made about 1500 gallons before having to change all the "soiling filters" (Everyhing but the RO membrane) - the unit is $250 and a complete filter change is $50
Do I drink this water? NO
I add a specific mineral mix to it to reconsitute it for fish to live in. And they get perfectly mixed water -- makes the things breed like crazy! We have blue rams and angelfish spawning at will in our community tank [the rams babies end up getting eaten by the corydorae after they hatch because the rams then move them to the bottom - we remove the angel egg clusters to prevent them from becoming picsicydal (fish killers)]

Why?
Tap water parameters:
PH 9.2
Hardness: 350 ppm
Addatives: Chlorine, Chloramine, Flouride (all fish-poisonous)
Mineral Contaimnants: Copper (deadly to fish), Zinc (ditto), Magenesium, etc
Microbial Contaiminants: Oodinium (hazardous to fish, and humans in high enough concentration, Oodinium is known to survive water treatment plants) and other unkown microbes
