Description
Track your pool or spa stabilizer levels accurately with the Valterra Blue Devil Cyanuric Acid Test, an 8-ounce reagent refill made for Blue Devil Test Kits. Cyanuric acid functions as a protective shield for chlorine, slowing its degradation under sunlight and keeping sanitation effective throughout the day. To perform the test, introduce the reagent into a water sample as specified by your test kit instructions, then evaluate the outcome to see whether stabilizer adjustments are required. Works with the full range of Blue Devil Test Kits.
