To make pool chlorine last longer, consider using stabilizer chemicals to protect against UV degradation, regularly cleaning and maintaining pool equipment, and using a pool cover to reduce evaporation.
To clean pool water naturally, consider using alternatives to chlorine such as salt water, ionization, or ozonation systems. You can also use natural enzymes or bacteria to break down contaminants.
The amount of chlorine needed to maintain a pool can vary based on pool size, usage, and other factors. Typically, it is recommended to keep chlorine levels between 1-3 ppm.
To winterize a pool, clean and balance the water, drain the pool equipment, and add winterizing chemicals to protect against freezing and other winter damage.
