Readings:

Time: 15:20
Inside Temp: 100F
Outside Temp: 91F
Relative Humidity: 60%

Normal chores in the GreenHab were performed. The chores are pumping gray water into the tanks, watering the plants, and taking temperature/humidity readings.

Measurements Taken:

Tank #1:	pH = 8.4	Ammonia = 4	Nitrate = 40	Nitrite = 6
Tank #5:	pH = 8.4	Ammonia = .1	Nitrate = 10	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). As a quick check, the pH color strips were tested against pH buffering solutions of known pH, and seemed to correlate well.

The sump pump was tested this morning, with a good flow into Trickling Filter Reservoir #1 seen. Water was spraying into TF #2, over the bioballs, and there appeared to be a slight increase in TF #2 water level, but the water level in Trickling Filter Reservoir #2 was still so low as to preclude any further movement to the tank system. Later in the day, the sump pump was run again, and there was some ensuing flow into Tank #1. About 10 gallons of water were added to the Hab TST (Toilet Supply Tank).
