Observation 4 11/6/08

Week Four observations began with a tiny slip. The microaquarium fell from fingers as I was getting it positioned on the microscope, and I lost nearly a third of the tank's water. I replaced the lost water with some provided by Dr. McFarland, but the damage had been done. The tank seemed to have undergone a massive die off during the time between observation 3 and 4. A number of Diatoms could still be found in various places throughout the tank, but much of the life that had previously been there seemed gone. Multiple unshelled rotifers were found at plant A; however, plant B appeared nearly entirely void of life.
