Okay, so... For my own sanity, I retested just now about 5 hours after WC, and these are the results I got:
Ammonia ~ 1ppm
Nitrite: still looks off the chart, but I am not completely sure. When I first dropped into the vial, the drops turned blue before shaking it, rather than purple immediately like before. The violet shades on this test are hard to read.
Nitrate: seems about 10-20ppm?
PH: looks somewhere between 7.2-7.6?
Am I correct that I am getting back on track as far as PH and Nitrate goes?
I ran the high range PH test, and it came out at about 7.4, so I know that the PH is back on track.
