– While it might look and feel nice to have your pool in a sunny location, it’s actually not good for the pool water. “Chlorine, which keeps your pool from turning green, dissipates in direct sunlight. You put liquid chlorine in a sunny pool on Monday and by Wednesday it will have almost no chlorine in it,” explains Willan Johnson, CEO of pool-management company Vivo Pools. He continues that “algae breeds a lot more in 100 degree weather than 60 degree weather,” which means that a pool getting hit with direct sunlight all day is going to become a breeding ground for germs and algae, even with chlorine in your water.
