| Day 20
Finally I see some changes...the ORP has climbed back to 250 (my usual reading).
TDS,pH and nitrates still the same.
I note the BS/BH has done nothing to my DO (yet?) which I have expected.
Yet to note any extraordinary change in water physical appearance (same crystal clarity), koi appetite or skin lustre.
Still significant sedimentation in 1st chamber. I don't think this will ever stop.
