Having a visually clean pool is important but just as important is having a balanced pool! The balance of the water is not only important for the safety of you and your family’s health but also to insure that the “finish” of your pool and its equipment stays intact. There are several items that affect the health of your pool that CBP will monitor and adjust using only the necessary amount of chemicals to maintain proper balance.
Total Alkalinity (TA) - When the total alkalinity (TA) is within this range, it prevents rapid pH changes and "stabilizes" the pH level. If the TA is too low, plaster walls can become etched, metals corrode, the pool's walls and floor can stain, the water can turn green and you can have a PH “Bounce”. If the TA is too high, the water becomes cloudy and loses its sparkle and the chlorine loses its efficiency as a disinfectant.
PH level - It is one of the most important factors in a healthy pool. Anything lower than 7.2 will be acidic water and anything higher than 7.4 is considered high PH. A low PH can result in algae growth and metal corrosion (pool equipment) which can cause the formation of pool staining sulphates. Chlorine also dissipates more quickly allowing for bacteria growth. A high PH allows for the formation of scaling along the water line, and causes cloudy water as well as affecting the filter’s ability to remove debris.
Calcium Hardness - If calcium levels are too low water can become corrosive and stains can form. If the Calcium levels are too high, the result will be scale formation on all pool surfaces and clogging of filtration equipment thereby reducing water flow and filter efficiency.
Stabiliser or Cyanuric Acid - Because chlorine is unstable, the Sun’s UV rays and high temperatures can affect the chlorine’s ability to disinfect your pool’s water. Stabilizer protects the chlorine from breaking down and reduces the amount needed in order to disinfect your pool.
Chlorine - The amount of chlorine in the water is important to protect the safety of the water for swimmers. And keeping the minimum amount needed in order to keep the water clean is ideal. Low chlorine content can result in algae and bacteria growth, cloudy water and insufficient sanitation. Too much chlorine can lead to irritation of the skin and eyes.
Total Dissolved Solids - TDS is influenced by many factors; the chemicals we add to adjust the pH, chlorine, water hardness, alkalinity, dust, and dirt. As pool water evaporates the total dissolved solids will become more concentrated. When the TDS is high, the harder it becomes for chemical additives to work and stains can form. The best way to insure proper TDS is to maintain your pool as well as regular backwashing.
