Experiment
  • The purpose of our experiment is to simulate the
    effects of fertilizer runoff.
  • Every week approximately .58 grams of KNO3 is
    added to the tank, and then nitrate levels are
    measured after 10 minutes of adding the KNO3, and
    after a week.
  • Our expected results were that the excess
    nitrates would be used by algae, and have a
    negative effect on the aiptasia due to decreased
    light intake

Nitrate Levels
  • Originally we increased the nitrate to 25 ppm,
    and assumed that it would be used in a week.
  • After a week, nitrate levels actually went up.
  • Another .58 grams of KNO3 was added after the
    first week, and nitrates increased to 62 ppm.
  • Last week we tried to measure the nitrate before
    we started our tests, but they were too high, and
    we were unable to read them
