What is cyanuric acid?
This is an ingredient found in many chlorine products that help protect the chlorine from being burned off by the sun. Think of it as sunscreen for your chlorine. The problem is hot tubs are rarely ever left out in direct sunlight for hours at a time so there is no need to have cyanuric acid (CYA) in hot tub water.
Why does cyanuric acid cause problems?
When cyanuric acid (CYA) builds up, it actually makes chlorine less effective. When that happens the chlorine can’t keep up and you start to experience cloudy water with smelly odors and end up spending more time and money trying to keep the water clean and clear.
How do I know if my hot tub has too much cyanuric acid?
A simple test will tell you. You can take a water sample into your hot tub retailer or get a free CYA test trip by clicking here. If the parts per million (ppm) level of cyanuric acid is over 50 ppm, taking care of the water will become much harder. At 100 ppm, you really have no choice but to drain the water and start again.
