Test pH, hardness, alkalinity (buffering capacity), nitrite and nitrate all with one dip. The technology used in Mardel test strips is the same technology that physicians, clinics and hospitals use to screen for health conditions. Test strips contain absorbent pads saturated with a specially blended set of nontoxic chemicals that turn different colors when exposed to certain substances in water.

Mardel Test Strips provide a quick, accurate, nontoxic and easy to use method to detect adverse water conditions. Because test strips consist of small plastic sticks with absorbent pads attached there is no need to handle dangerous and messy chemicals.

Simply dip the test strip in tank water and remove, wait 60 seconds then compare pad color to the color chart provided.
