Use chlorine as your go-to algae killer. When your pool water is green or contains visible algae clumps, your pool does not have enough chlorine. Shocking the pool with a large dose of chlorine is the most effective way to kill the existing algae and bring your pool back to sanitary conditions.
Why Does My Pool Keep Turning Green? Recurring algae can be a problem this time of the year. There can be several contributing factors, heat, rain, letting chemicals get out of balance, and even transfer form one pool to another. Recurring algae is usually Mustard Algae. It is a yellowish green color that usually starts growing on the pool walls and on the pool floor. It will then turn the pool water green.
