AquaChek Pink Nitrate – 25 Strips

AquaChek Pink Nitrate/Nitrite tests use the most accurate method for nitrate/nitrite testing: a one step, one minute, nitrate/nitrite test. Check nitrate/nitrite levels if you are seeing excess chlorine demand. Positive nitrate test also indicates the potential for algae growth. For a clean and healthy pool, test the water at each end a minimum of twice a week!
