Description

Last summer, many fresh water lakes began their mornings with the stench of hundreds of dead fish. The cause was an overgrowth of algae in lakes. Bacteria ate the algae and when this happened, oxygen was taken out of the water. When there was too much algae, there was not enough oxygen for the fish, and they died, in large quantities. Unnaturally large amounts of algae in lakes have become a common problem in America. The goal of our project was to create a device that can remove algae quickly and easily, and do so without disturbing each lake’s fragile ecological system, to save our lakes and our fish. Using natural water collected from a pond, we created an environment ideal for algae growth. We used special cloth filters normally used in landscaping, and sent samples of our pond water through a variety of filter types and sizes. We tested each filter to determine which one was most efficient in removing algae. The filters we used were created to be environmentally friendly, so we know the best results of our project will also be the best for protecting the wildlife in our lakes.
