I received and set up my first RODI unit today. After letting it run for a bit and making sure there were no leaks, I went about testing the water so that I could compare it to my tap water and make sure everything is working.
Tap water (with 24 hr aeration)
pH: 8.6
KH: 17 (304ppm)
GH: 15 (268ppm)
TDS: 561
RODI water (no aeration)
pH: 7
KH: 0
GH: 0
TDS: 0
Im assuming that this is exactly what I want, but I wanted to check in with forum folk and be extra sure. The one thing that threw me was that, while conducting the KH and GH tests, the water never really turned any color. It just sort of stayed clear. There may have been the slightest of yellow and orange tinges to the water after one drop each, but I would ultimately describe the color as clear. Is this typical? Does the absence of everything (but H2O) confuse the KH and GH tests?
