The Taylor R-0013-E Cyanuric Acid Reagent is a crucial component for maintaining safe and balanced pool or spa water. This 16 fluid ounce bottle is a direct replacement for depleted reagents found in various Taylor test kits (like the K-2005), providing an economical way to keep your testing supplies fully stocked. 

Cyanuric acid (CYA) levels are vital for outdoor pools, as CYA shields chlorine from rapid degradation by the sun's ultraviolet (UV) rays. The R-0013-E uses a reliable "turbidity" test method: when added to a water sample, it creates a precise cloudy solution that is measured against a viewing tube scale to determine the exact CYA concentration. 

Key Performance Features

• Essential for Testing: Accurately measures cyanuric acid (stabilizer) levels to ensure effective sanitization and balanced water chemistry.
• Genuine Taylor Refill: Official R-0013-E reagent ensures compatibility and reliable results with all Taylor test kits.
• Cost-Effective Solution: A convenient pint-size bottle that is more economical than purchasing an entirely new testing kit.
• Reliable & Accurate: Taylor formulates its reagents to remain effective for at least one year when stored properly between 36°–85°F (2°–29°C).
• Easy-to-Use Method: Designed for use with standard drop-test kits and a viewing tube comparator.
