It's a list of all the people and things I hate so much I want to hit them in the face with a shovel.. Concept coming from the Marian Keyes novel, The Mystery of Mercy Close (2012).
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.
Algae doesn't need to be the bane of your existence. The simplest way to get rid of algae is never to get it in the first place. If you maintain the appropriate free chlorine (FC) level at all times, algae will never be able to get started. The earlier you catch algae, the easier it is to get rid of.
