AquaChek 641426E Swimming Pool and Spa Nitrate/Nitrite Test Strips, 25 Strips

AquaChek's Nitrate/Nitrite test strips give pool owners an easy, effective way to test for high nitrate/nitrite levels in their pool or water, which can cause uncontrollable algae growth and chlorine depletion that wreck pool usability. Considered the X-factor when diagnosing difficult pool problems, these test strips produces a quick, accurate reading of your nitrate-nitrite levels, which if high can be treated to restore chlorine's normal effectiveness and eliminate out of control algae.

This product can also be used for jacuzzis, aquariums, ponds and other water sources where nitrate or nitrite levels need to be kept in check.
