I use the arrowhead spring water for my tads. I will add a little tad tea or Methyl blue. Add an oak lead or two. Nothing else done to the spring water.
For misting tanks though distilled water only, or you get the hard water mineral deposits on the glass.

Blackwater extract is excellent. It is just cheaper to go up in the foothills near my home and collect oak leaves to boil and make tad tea.
