Normal chores in the GreenHab were performed. The chores are pumping gray water into the tanks, watering the plants, and taking temperature/humidity readings. Lately has included moving the plants from the GreenHab at dusk, and returning them after sunrise.

Measurements Taken:

Tank #1:	pH = 8.4	Ammonia = .4	Nitrate = 5	Nitrite = 0
Tank #5:	pH = 8.4	Ammonia = 0	Nitrate = 5	Nitrite = 0

These reading were taken using the freshwater scale, as instructed. Color match was inexact, but readings were interpolated, and approximated as closely as possible to the color scale. The coloration for pH, in particular, was so intense as to indicate that the actual pH was even higher than the 8.4 value (highest value given on the color scale).

The sump pump was tested this morning, with flow into Trickling Filter Reservoir #1 seen. The water level in Trickling Filter Reservoir #2 is so low as to preclude any further movement to the tank system. One bucket of water was added to the Hab TST (Toilet Supply Tank).

The immersion heaters have been placed into TF Reservoir Tanks #1 and #2, and are ready to go when we receive the temperature settings. If the space heaters are replaced by the immersion heaters, temperatures in the GreenHab may drop low enough to impact the BYU experimental plantings, although there should be a saving in energy consumption.

The solar panels on the south wall of the GreenHab are producing 12 vDC, as is the external Power Pod.

We are just about out of rubber gloves, which are used for the testing of pH, ammonia, etc., with test strips.
