How is algae in the Lincoln Memorial Reflecting Pool managed?

The algae in the Lincoln Memorial Reflecting Pool are kept under control with a special kind of cleaning schedule and some help from water filters.

Imagine you have a big bathtub that's always full of water, and sometimes little green spots appear on its sides, that’s what happens to the reflecting pool. Those green spots are algae, which grow when there's not enough movement in the water or when it gets too sunny.

1. Every so often, workers come with big machines and vacuum out the algae, just like you might use a vacuum to clean your room.
2. Sometimes they also add special chemicals into the water that help stop the algae from growing too fast, it’s like giving the pool a little treatment to stay healthy.

The reflecting pool has water filters, which work like strainers in your kitchen sink. They catch tiny bits of dirt and algae so they don’t spread all over the water. This keeps the pool looking clear and shiny, just like how you might use a filter to make your juice look prettier.

By using these methods together, the workers keep the Lincoln Memorial Reflecting Pool clean and ready for everyone to enjoy!
