AquaChek 641426E Swimming Pool and Spa Nitrate/Nitrite Test Strips, 25 Strips
These 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. Dip and read test strips give
results for both in less than one minute. For a clean and healthy pool, test
the water at each end a minimum of twice a week.
