You need an algaecide.
Algae can grow on the walls and bottom of your pool and in your pool water after a rainstorm, during cloudy stretches or if your pool isn't properly maintained. If using an algaecide doesn't work, you might not have enough sanitizer, the circulation could be poor or you've got improper filtration.
You need shock.
Treating your pool water with shock once a week helps eliminate waste products, like sunscreen, from the water. When the weather gets warmer and you've got more swimmers, you'll also need to add shock.
