Description
Protect your chlorine’s effectiveness with the Valterra Blue Devil Cyanuric Acid Test B7518, a 32 oz professional-quality reagent that accurately gauges cyanuric acid (stabilizer) levels in pool and spa water. Because cyanuric acid acts as a sunscreen for chlorine, keeping it within the proper range prevents rapid sanitizer depletion caused by UV rays. This mid-size bottle strikes an ideal balance between value and convenience, producing clear, consistent readings that simplify ongoing water chemistry management for both home pool owners and commercial operators.
