How To Test For Calcium Hardness in Your Swimming Pool

Taylor swimming pool test kits are the best!

If you live in many parts of the United States and especially the Southwest United States, dealing with hard water issues is extremely common. “Hard water” specifically refers to calcium, magnesium and other hardness minerals which are common and extremely high in our tap water. With high levels of calcium hardness in your swimming pool comes many troubling issues and that is what we want to discuss in this blog post. Calcium hardness causes scaling to occur on our shower heads and faucets, it leaves spots on our counter tops, cars, dries out our hair and can be hard to remove when scaling has occurred. Knowing what it can do in your house, car, and to your appliances have you ever thought about what it does to your swimming pool? If you allow calcium to rise in concentration in your pool water it can destroy your filtration equipment, interior finish and can be an eyesore to look at. With that said, we want to explain what it does to your swimming pool, why you should test for it and how to test for it too!

As pool water evaporates, calcium remains in solution and gradually builds up in concentration. When levels get high scaling occurs on the water tile line, interior finish of the pool, filtration equipment, spillways and decorative tile. As this water runs through the pool plumbing it also scales your plumbing as well. Ultimately, if you decide to leave it untreated or choose not to change out the water in your swimming pool regularly it can cause thousands of dollars in damage to your pool and can be extremely expensive to remove. At Pool Services Technologies, we want to make sure you understand the importance of why you should test for it and why using Taylor test kits is your best choice to check the levels.

We use the Taylor reagents and speedster because they are easy to use and extremely accurate. The following is a step by step guide to follow that will teach you how to test calcium hardness:

  1. Add pool water to the plastic container and add the pill (magnetic stirrer).
  2. Turn the speedster on.
  3. Add 20 drops of reagent R0010 to the water which neutralizes it and prepares it for testing.
  4. Add 5 drops of reagent R0011 to the water which will turn it a pinkish color.
  5. Add drops of reagent R0012 to the water and count the drops, each drop has a value of 10 parts per million
  6. Stop using reagent R0012 when the water turns blue. At this point, you can take the number of drops and multiply it by 10 to get your parts per million calcium hardness.

For example, if you dropped 100 drops of R0012 into the mixture you will have 1000 parts per million (ppm) calcium hardness in your swimming pool water. Typically, you will want 200 – 400 ppm in your swimming pool so anything above that is considered high.

Simply put, high levels of calcium hardness can and will destroy your swimming pool. Do yourself a favor and order a Taylor swimming pool test kit today!
