I live in Minneapolis MN. We get our tap water from the Mississippi.
The city sends out a water quality report http://www.ci.minneapolis.mn.us/water/docs/2010_Drinking_Water_Addendum.pdf
This doesn't tell me why the KH is around 3 degrees and the GH seems to be anywhere from 5 to 12 degrees and the pH is around 7.6.
This link http://www.ci.minneapolis.mn.us/water/docs/2010_Drinking_Water_Quality_Report.pdf
tells me that
(Averages in ppm)
Total Alkalinity: 32
Total Hardness: 71
Total Residue: 191
pH: 8.75
Oh ok. So my testing isn't way off but why.
So this is soft water with a really high pH.
The last link also states "We add to the water a chemical buffer that’s safe and prevents the water from interacting with
the metal plumbing. We also maintain a slightly elevated pH in our water, which keeps it from reacting
with the metal."
I am assuming that the total residue has a few buffers like phosphate and what not.
It seems I am doomed to thrive in keeping South American fish.
I am a fool.
I don't know what to do.
