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.
6) 24 hours after step 5, shock the pool again. The pool will clear up within the first 24 hours (no more sickening green/yellow color). 7) allow the pool to return to normal levels - test the water and make adjustments as necessary. Mustard algae will return in force if you don't get it all. Make sure the levels of chlorine are kept to the optimal for your system.
