These results have not changed since Week 4, It is definitely because of the sufficient water changes per week. The same results are shown in Week 6 as well.  From week 4, I noticed that i could not see my fish because the water was so murky. I was very worried about my fish. I realized that the water was not murky and unhealthy because the water chemistry results shows that it is balanced. Why was it looking so green and murky? Then it clicked, ALGAE! There is so much algae on the jar and in the tank. I Picked the plant up and examined the tank from a superior view, The water was clear and i could see the fish! The circumference of the jar was covered in slim and algae. The Jar was not been cleaned since the duration of this experiment. The reason there is such a large amount of algae in BPI2 is because its i direct sunlight. Algae need sunlight to grow. Out of all the experiments, my jar is the most green. To control the growth of Algae, the Jar should be kept in a darker place. The other way is to limit the light source, what i mean by given your plant and fish a time limit in the sunlight. This will help control the growth of Algae. That is Just a small tip for next years experiment:)
