 Tests for the 42 gal hex:
Sunday night (the day after adding all livestock with well-cured rock):
  ammonia 0 ppm
  nitrite 0 ppm
Wednesday afternoon:
  ammonia 0 ppm
  nitrite barely registering a colour change which I judge to be .01 ppm
  (This must be the beginning of the spike!!!!  Egads!!)
Still some scum on the 42's surface.  Tilted the 802 a little more upward, and added a second source of surface agitation at the other end of the back panel of the tank - a Whisper that came with our 2.5 nano - and filled the media chamber with a Mini foam.  This puny thing just barely moves any water compared to the 802, but it moves it right at the surface, so it may end up being useful afterall :-)
