Hardness Test Strips allow you to easily test the level of calcium or 'hardness' level in your spa's water. Easy to use. Results in 15 seconds!
Use to measure the level of calcium, or "hardness" in your spa's water.

Each strip has a single pad, and there is a simple color chart on the back of the bottle for you to compare the results on the strip. The color of the pad indicates the current Water Hardness level in your spa's water.

Test the Water Hardness bi-weekly, especially if you have soft water that needs to be hardened with Liquid Calcium.
