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.
Know the different types of pool algaecide. 1  Copper-based algaecides use copper to treat algae growth, and are most effective against mustard and green types of algae. 2  Copper algaecides will not cause foam in a swimming pool, which can be a problem when using âquat algaecides.. Add preventative algaecide to your swimming pool on a weekly basis if you regularly experience problems with algae growth. If you have never had an algae problem in your swimming pool, there is no need for the algaecide.
