OK the first test is running now. Optimum car soap was chosen randomly as the first test.
All glassware was first cleaned with a 10% HCl acid wash, then rinsed extremely thoroughly with tap water, then triple-rinsed with distilled water, and finally rinsed with the control water.
I made 6 beakers for this experiment. A control beaker with 80mL of control water, a 1:1000 beaker with 80mL of solution, a 1:10,000 beaker with 80mL of solution, a 1:100,000 beaker with 80mL of solution, a 1:1,000,000 beaker with 80mL of solution, and a 1:10,000,000 beaker with 80mL of solution.
The control water is straight from our fishtank filtration system. The water goes through an activated carbon filter, through the fishtanks, and then into a sand filtration system. The control water was obtained immediately after leaving the sand filter.
6 Daphnia magna neonates < 4 days old were placed into each beaker, and the 6 beakers are being stored at ~72*F.
After 48hrs the test will be completed, and I will then examine all of the D. magna to determine mortality rates. A microscope will be used to confirm that the organism's heart has indeed stopped beating.
