Cyanuric Acid : When it comes to pool chemistry, more isn’t always better. This is especially true for cyanuric acid (CYA). While it plays a critical role in stabilizing chlorine and preventing it from degrading in the sun, excessive levels of CYA can weaken chlorine's effectiveness , leading to cloudy water, algae growth, and unsafe swimming conditions. In this guide, we'll show you how to identify high CYA levels, what causes them, and the safest methods to lower cyanuric acid in your pool. 🔍 Signs Your Cyanuric Acid Is Too High Persistent cloudy water Chlorine demand increases, but effectiveness drops Algae growth despite proper chlorine levels Test readings show CYA over 80–100 ppm (for traditional pools) High CYA can lock up chlorine, making it "inactive" even when levels seem sufficient. ✅ What Causes High CYA Levels? Overuse of stabilized chlorine products (trichlor, dichlor) Infrequent water changes Using CYA products without testing existing levels If you ...
