What should hot tub test strip read?
Hear this out loudPauseThis time you are looking at the middle patch on the test strip and checking against the Alkalinity (Alk) scale. Ideally, the Total Alkalinity of your hot tub water should be between 80 and 120 parts per million (ppm). If it is within this range, you can then adjust the pH level as required.
How do I know my water hardness number?
Hear this out loudPauseWater hardness can be easily measured using a simple soap test kit that will measure in “grains of hardness” (a little bottle with a line marked on it which you fill to the line with water, add a drop of soap, and shake to look for suds. More drops of soap – more degrees of hardness).
How do you read a bioguard test strip?

What is normal water hardness?
Hear this out loudPauseMeasures of water hardness General guidelines for classification of waters are: 0 to 60 mg/L (milligrams per liter) as calcium carbonate is classified as soft; 61 to 120 mg/L as moderately hard; 121 to 180 mg/L as hard; and more than 180 mg/L as very hard. Lime scale buildup inside a water pipe.
What is FCI on test strip?

What causes water hardness on a hardness test?
Total Hardness Test Strips, 0-425 mg/L. Water hardness is caused almost entirely by calcium and magnesium ions. Other di- and trivalent metals have a similar effect, but usually are not present in high enough concentration in potable waters to cause problems.

How does the color change in a hardness test?
Testing. The color progression in a hardness test is from red, to a mixture of red and blue, to blue. To be certain the color change is permanent, indicating you have reached the true endpoint, add one more drop of titrant. If the blue color remains unchanged, do not count this drop.
How does a drop test for calcium hardness work?
To perform a drop test, simply fill a test cell with sample water, add buffer and indicator reagents, and swirl to mix. The sample will turn red if calcium hardness is present. Next, add the calcium hardness reagent, swirling and counting each drop, until the color changes from red to blue.
