Product Overview

The Taylor Cyanuric Acid Reagent | R-0013-C-12 is genuine Taylor Reagent #13 in a 2 oz dispenser-tip bottle. It is the replacement reagent used to test cyanuric acid (stabilizer) levels with Taylor pool and spa test kits.

Cyanuric acid protects chlorine from being broken down by sunlight, but too much reduces chlorine effectiveness. Reagent #13 reacts with cyanuric acid in the water sample to produce a cloudy solution, letting you read the level accurately.
