The free chlorine to cyanuric acid ratio (FC:CYA) is paramount for effective disinfection in swimming pools. It matters more than just free chlorine ppm! In short, cyanuric acid fundamentally changes the chlorination game.

2024年7月20日 · In this article, we’ll show you how to use our FC/CYA calculator to determine your pool’s ideal chlorine levels and keep your water safe and clear all season long. Use the selector below to choose your goal and current CYA level. Which best describes your goal?

Adjust sliders to calculate pool stabilizer. PLEASE FILL IN ALL FIELDS! The main purpose of stabilizer (also known as Cyanuric Acid, CYA or Conditioner) in the water is to protect chlorine from the destructive Ultraviolet (UV) rays of the sun.

Cyanuric Acid: 30–50 ppm; Free Available Chlorine: 2.0–4.0 ppm; pH Chart. Use this pool pH dosage chart to determine how to properly adjust the pH level in your pool. A low pH of 7.1 is desirable when using chlorine and sock, but 7.4 is best for swimmer comfort, surface protection, and overall water balance. Lowering pH with pH Reducer

2024年11月22日 · What is Cyanuric Acid (CYA)? Cyanuric acid, often called a stabilizer or conditioner, is an organic chemical compound added to pool water. CYA does not naturally occur in water and will only be present if added. What does Cyanuric Acid do in Pool Water? Cyanuric acid interacts with chlorine in two distinct and significant ways:

CYA - Cyanuric Acid. Cyanuric acid, often called stabilizer or sometimes conditioner, both protects FC from sunlight and lowers the effective strength of the FC. The higher your CYA level, the more FC you need to get the same effect. It is important to know your CYA level so you can figure out what FC level to aim for.

2024年7月3日 · To check what FC range you should be in, plug in the current CYA of your pool: You can also refer to this chart for a full overview of the FC and CYA relationship: Notice how much chlorine is needed to be effective when CYA starts to climb up. This is why testing CYA is crucial to ensure it’s always at a balanced level.

2024年7月23日 · Your current CYA level; Your desired CYA level; The calculator will let you know how much CYA you need based on your pool’s size. It’s important to note that CYA can only be decreased by partially draining and refilling water. With this in mind, add CYA in increments and test along the way.

2017年12月30日 · The amount of sunlight exposure and cyanuric acid (CYA) help to determine how much free chlorine your pool requires. Cyanuric Acid, a water stabilizer/conditioner, reduces the damaging effect of the sun’s UV rays on free chlorine.

2018年7月16日 · Cyanuric Acid – 20 to 50 ppm Free Chlorine – 2.0 to 4.0 ppm . Pool pH Chart. Use this pool pH dosage chart to determine the correct amount of pool pH adjustment chemical to add for a desired change in pH level. A low pH of 7.1 is desirable for shocking and sanitation, but 7.4 is best for swimmer comfort, surface protection and overall water ...
