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.
Mustard algae is rare and often mistaken for sand, dirt, or a stain in your pool. Itâs not slimy like regular green algae, but it likes to attach itself to pool walls and other items. Itâs also chlorine-resistant and very stubborn. It can even live outside of your swimming pool.
