Created specifically for pools or spas that are disinfected with chlorine, AquaChek Yellow contains a specific test for Stabilizer (cyanuric acid) that is especially important in outdoor pools or spas that are subject to chlorine dissipation by UV rays. I also control the free chlorine, pH and alkalinity values.
Immerse the analytical strip in water and remove immediately. Wait 15 seconds with the analytical strip facing the test side up (do not remove excess water). Compare pH, free chlorine, total alkalinity, and stabilizer tests (in that order) with the color chart provided.
