Lowering Cyanuric Acid in Swimming Pools Just Got Easier

If you've ever had a pool that just won’t stay clean, no matter how much chlorine you use, you're not alone. This is a frustration nearly every pool owner faces at some point—and the root of the problem is often hidden. The issue isn’t your chlorine itself; it’s the stabilizer levels, specifically cyanuric acid. While CYA plays a helpful role in protecting chlorine from UV breakdown, too much of it turns into a major problem.

High CYA causes a condition known as chlorine lock, where chlorine is technically present but chemically unable to do its job. This means you can test your water and see normal chlorine levels, yet still struggle with algae, murky water, and unpleasant odors. If you’re wondering how to lower cyanuric acid in a pool, you’ve probably come across the old advice: drain and refill. But let’s face it—that’s not practical for most people. It wastes thousands of gallons of water, takes hours, and creates room for more water balance issues afterward.

That’s why more pool owners are switching to a safe, natural, and proven way to lower CYA without the mess or waste. Bio-Active Cyanuric Acid Reducer is designed to solve this exact problem. Our product uses advanced biocatalyst technology to break down cyanuric acid molecules in the water. It’s nontoxic, nonpolluting, and nonallergenic, which means it’s safe for your family and won’t harm your pool equipment or water chemistry.

This is the ideal choice for anyone trying to lower cyanuric acid in a swimming pool without draining. Whether you’ve been using stabilized chlorine for years or just started noticing issues, Bio-Active makes the fix simple. Just add it directly to your pool water and let the pump circulate—it works on its own, no shocking or special equipment needed.
