4/13/15 Reports & Observations

*This week, the experiment ends and set ups will be dismantled. It's been fresh.

Reports:

Spring Break/Weekend Causalities: 0

Tank 1- Galactic Branch (Fish population - 4)

• Nitrate: 5 ppm

• Nitrite: 0 ppm

• Total Hardness: 200 ppm

• Alkalinity: 5 ppm

• pH: 7.0

• Vertical Behavior: Bottom

• Raw Plant Heights (cm): 10, 8, 6, 20, 17

• Average Plant Height (cm): 12.2

• Ammonia: 1.0 mg/L

Tank 2- Terrestrial Branch (Fish population - 5)

• Nitrate: 15 ppm

• Nitrite: 0 ppm

• Total Hardness: 200 ppm

• Alkalinity: 10 ppm

• pH: 6.2

• Vertical Behavior: Bottom/Middle

• Raw Plant Heights (cm): 10, 10, 9, 15, 14

• Average Plant Height (cm): 11.6

• Ammonia: 2.0 mg/L

Observations:

The massive increase in hardness (mineral content) is due to the feeding block minerals that dissolved in the tank to keep the fish nourished over the break. Plants in the Terrestrial Tank (2) were flourishing, unlike the plants in the Galactic Tank (1) that had significantly dried out over the break.
