7.1.8.Things to remember

• People swimming in the pool are the main source of bacterial contamination.
• The keys to maintaining water quality in your swimming pool include filtration, chlorination, pH level, total alkalinity (TA) and calcium hardness.
• Check your pH and chlorine levels daily - preferably, these tests should be done before the first swim of the day to make sure the water quality hasn't altered overnight.
