AquaChek Total Hardness 25 Test Kit Strips

Tests: Low Range and High Range Total Hardness

Our Total Hardness test strips measure calcium and magnesium, the two minerals that primarily make up hardness in water, up to 1000 ppm. High hardness contributes to scale formation and cloudy water. Low hardness can leave water aggressive and corrosive. Maintain appropriate levels of hardness to prevent the water from becoming corrosive or scale-forming.

Just dip an AquaChek Total Hardness strip in your pool or spa water for one second and remove it immediately. You get test results in seconds!

For a clean and healthy pool, test the water at each end a minimum of twice a week!
