Easy Testing Instructions
Easy Steps for Testing Hardness of Water:
- Tear open Water Hardness Test Strip package and remove test strip. Keep package to refer to key indicating levels of hardness.
- Insert the grayish-green colored end of the water hardness test strip into the flow of water for a few seconds then remove from water. We recommend you test the water you use to shampoo and bathe (shower or tub).
- After 12 seconds, compare water hardness test strip to key on side of test strip package indicating the levels of hardness.
KEY:
< Green = Soft < Brown = Hard Water < Orange = Very Hard Water
Easy Steps for Testing Chlorine in Water:
Note that chlorine evaporates rapidly. Therefore, test for chlorine as soon after you draw your water sample as possible.
- Allow cold water in shower or bath to run for one minute. Collect up to 2 ounces of cold water into a clear glass. Do not draw hot water.
- Pour contents of Chlorine Indicator (orthotolodine) into the clear glass and swirl the water around the glass.
- Wait a few minutes for chlorine indicator to reveal the amount of chlorine in the water.
KEY:
Clear = No residual chlorine in the water
Yellow = Chlorine is present in the water
Bright yellow or a greenish color = High level of chlorine is present and may even exceed the amount required by law for sanitation in public swimming pools
