Chlorine Demand Click Here: https://www.pinterest.com/bestpoolvacuumforalgae/ Chlorine demand is one of the most common problems that swimming pool owners face. It can be frustrating and confusing, and it may seem like a daunting task to solve. A good place to start is with understanding how chlorine is consumed in your pool and what factors are responsible for it. This includes the chemicals used in and around your pool and how much water is added to it from the local municipal supply or a lake or well. When you add chlorine to your pool, it oxidizes non-living contaminants in the water. This includes metals, nitrogen compounds, and non-living carbon-based bather waste that get oxidized when chlorine is added to the water. This can lead to the development of green algae, which is a major source of chlorine demand. It’s also important to remember that phosphates are a primary food source for algae growth, so removing phosphates from your pool can help reduce its growth rate.
