Just did first cycling water test.  The only parameter that has changed is the pH, which increase from 7.5 (from tap) to between 8 and 8.5.  Hmm.  Must look in to this.  Amm 0.6, trIte 0, trAte 0.

Also bought air lines and bubblers.  Hope to get that installed tonight.

ETA: Apparently pH is quite variable during cycling.  Will stop testing, and test only when cycling is completed.
