A: These hard water test strips measure the concentration of dissolved minerals — primarily calcium and magnesium — in your water.

A: Yes! These strips are designed for use with swimming pool water, hot tubs, spas, water softeners, and general household tap water. They are a quick and convenient way to monitor water hardness levels across a variety of water sources.
Q: How many tests can I run with one pack?
A: Each pack contains 30 individual test strips, giving you 30 separate tests. This makes the pack ideal for regular weekly or bi-weekly monitoring of your pool or water softener over an extended period.
Q: Do I need any special equipment or batteries to use these strips?
A: No — these test strips require no batteries, no electronic devices, and no additional equipment. Simply dip a strip into your water sample, wait a few seconds, and compare the color change to the reference chart included in the pack.
