๐จ Is your pool suffering from โchlorine lockโ?
Many pool owners think they need more chlorine when their water turns cloudy or green. But sometimes the real problem isnโt low chlorineโitโs excessive cyanuric acid (CYA).
When CYA levels become too high, it binds to chlorine and reduces its effectiveness. You may keep adding chlorine, but it struggles to sanitize the water properly.
Signs of possible chlorine lock:
โ
Chlorine tests normal or high
โ
Water stays cloudy or develops algae
โ
Constant need to add more chlorine
The solution isnโt always more chlorine. It starts with proper water testing and balancing.
Understanding water chemistry saves time, money, and frustration. ๐ง
