Current state:
PH - by controller - 7.2
PH - by 'low ph test' - 6.6
PH - by 'high ph test' - no higher than 7.4 (that's as low as the test goes)
KH - 5
GH - 125.3
Ammonia - 0
Nitrite - 0
Nitrate - 40 (maybe 80, tough for me to read the test)
So. Couple of questions. Look at those different PH readings. Something ain't right!
Could be the controller is bad, maybe I calibrated it incorrectly, maybe the PH test kit is bad or I took the tests incorrectly. I think my next move is to recalibrate the PH controller. It's a Milwaukee, I calibrated it with the 7 ph solution that came with it (I've done this type of thing before, successfully, too!
).
I know there's a relationship between PH, KH, and CO2 levels, so I've kept the controller set to about 6.6 (the KH reading last time was 4). I'll adjust that as I figure out the PH mess. Can someone tell me exactly what the GH is telling me, as I have no idea.

The E. Tennelus that is melting (kinda). I am getting new leaves, so that's good:
