To properly balance a freshly filled pool, you need to add the following chemicals. First, add a metal sequesterant to prevent staining if using a metal-rich water source. Next, adjust the pH level to fall between 7.2 and 7.6 using pH increaser or decreaser. Balance the total alkalinity to 80-120 ppm using alkalinity increaser. Add a chlorine shock or another sanitizer to kill bacteria and algae. Lastly, use a calcium hardness increaser to maintain hardness levels between 200-400 ppm.
FAQs & Answers
- Why is it important to add a metal sequesterant to freshly filled pool water? A metal sequesterant prevents staining and discoloration caused by metals like iron or copper commonly found in some water sources.
- What is the ideal pH range for pool water after filling? The ideal pH range for freshly filled pool water is between 7.2 and 7.6 to ensure swimmer comfort and effective sanitizer performance.
- How do you properly balance total alkalinity in new pool water? Total alkalinity should be adjusted to 80-120 ppm using an alkalinity increaser to help stabilize pH levels and prevent corrosion or scaling.
- Why is calcium hardness important in pool water maintenance? Maintaining calcium hardness between 200-400 ppm prevents water from becoming corrosive and helps avoid damage to pool surfaces and equipment.
