Mine seems to be pretty much a sodium bicarbonate solution. No calcium, no magnesium, no potassium, no nitrate, KH = 9.0, GH = 0. pH out of the tap is 8.5. Upon standing, some CO2 diffuses out, and the pH goes up to 8.6.
Weird! It is like hard water that has been through a water softener.
I don't like it. I collect rain water and use that. I throw some ground limestone in the tank to get some calcium and magnesium in the water and get the GH up to 3 or 4.
