Is There a Pool Urine Indicator Dye

Have you ever wondered whether there really is such a chemical as a pool urine detector or pool urine indicator dye? Such a dye supposedly clouds the water or produces a color when someone urinates in a swimming pool, as weve seen in movies and on TV. But does a urine indicator really exist? Is There Truth to the Rumor? No. There is no chemical which changes color when someone urinates in a swimming pool. There are dyes which could cloud, change color, or produce a color in response to urine, but these chemicals would also be activated by other compounds, producing embarrassing false-positives. Though there is no such thing as a  urine-detecting dye, you can purchase signs that prey upon the misconception that a urine indicator exists. The signs, which warn the pool is being monitored with a chemical wee alert, are believed to be an effective deterrent against urination in a pool, particularly with adult swimmers.
