Today I switched the bulb on the light for the experimental beaker from a 90w bulb to a 15w bulb. I had to replace the Daphnia in the experimental beaker because the daphnia from before had died. I took all the live daphnia in the control beaker, there were 11, and replaced the water in their beaker. I fed both beakers one pellet of daphnia food each.
