Abstract-
With the rise of fertilizer runoff, algae overgrowth is becoming a larger problem everyday. This has many negative effects on the environment, like drowning out other wildlife inside waterways. A cost-efficient device for eliminating algae would be useful for countering red tides and the effects. The purpose of this experiment is to test the possibility of using a floating lens design to remove excess algae from waterways without harming wildlife. The test sample was made by growing algae in a clear container outside, while gradually adding water. The test device was made by placing a concave lens inside of a pool floater. When placing the device in algae laden water, it should theoretically eliminate a large amount of algae.
