In our second observation, we have noticed that the water is not as clear as it was last week. There are particles and what appears to be algae floating around in the water. Our snail was very active and stuck to the side of the bottle. We cannot find the Daphnia in the bottle, but the water is so dirty it would be hard to see them. There is some condensation above the water line and in the top of the bottle above the dirt. We do not see any plant growth yet. The tips of our plant in the water are not as green as they were last week.
