How To Use A Liquid Test Kit

How to test your pool water the right way

For regular maintenance testing, you really only need a basic liquid test kit. Just make sure it includes phenol red and orthotolidine to test pH and chlorine, respectively.

  • Collect a water sample in the collector provided in the test kit.
  • On the side designated for pH testing, add the recommended number of drops of phenol red to the water.
  • On the side designated for chlorine testing, add the recommended number of drops of OTO to the water.
  • Hold the collector up to a white background, and compare the colors of the water to the color scales on the collector. The redder the water, the higher the pH, and the yellower the water, the higher the chlorine level.
  • Important: If the levels are low, the water colors will be fainter, and can be difficult to see. For higher accuracy, be sure to hold the collector up to a white background. Just a sheet of printer paper will do.

    How To Use Liquid Test Kit

    The two pool water test kits I use and recommend are the Taylor K-2006 and TF-100. For quick and easy pool water testing, you can use use a basic 4-way kit that includes phenol red and orthotolidine to test pH and chlorine. Your OTO kit comes with a 2 compartment vial. One side is for testing the pH and the other side tests for chlorine. To test your water using a 4-way test kit you will:

    • Collect the water sample using the vials that are included with your test kit.
    • Per the instructions for the pH, add the recommended number of drops of phenol red to the corresponding vial.
    • Per the instructions for the chlorine, add the recommended number of drops of yellow OTO to the corresponding vial.
    • Place the caps on the vials and gently shake for a few seconds to mix the solution.
    • Hold the vials up to a white background and compare the colors of the sample water to the corresponding chemical chart. Bright red indicates a higher pH. Bright yellow going to orange indicates high chlorine. Light or faded yellow indicates a low level of chlorine.

    Testing & Measuring Basics

    Keeping clean water in your requires that you maintain correct water chemistry. Although the word chemistry may seem intimidating, the process is actually very simple. There are four or five measurements to take, and some simple actions to take based on that information. The four key properties to monitor are Chlorine Level, pH, Alkalinity, and Calcium Hardness. Pools that use a saltwater chlorine generator will also require salt levels to be measured. Continue reading to learn about basic test kits, or you may skip directly to our recommended kits.

    How Often Should I Test For Salt

    To maintain the right salt level and keep your chlorine at 2 – 4 ppm, you will want to maintain your salt level between 2500 – 4500 ppm. This is the industry average, but always follow the manufacturer’s suggested salt level. Salt test strips can be found online and at your local pool store. Your pool store can also test for salt levels when you take your water sample in. It’s quick and easy for them to do.

    Test strips are the go-to for most pool owners, and salt water test strips are just like regular test strips. Get a sample of pool water, dip the salt test strip into the water, remove it, then wait for about 15 – 20 seconds for the results to show.

    Chlorine Pools Vs Salt Water Pools

    How to Use a Pool Test Kit to Check Water Quality

    A sparkling pool where you can relax is like a slice of paradise, but only when you maintain it most appropriately.

    Typically, there are two ways of maintaining the water quality of pools chlorine pools and saltwater pools. And while each of the two methods come with awesome features, it is essential to know the differences.

    Test Chlorine And Ph Levels Daily

    Gauging water quality begins by monitoring pool chemical balance. You must be aware of specific chemical levels throughout the year.

    This begins by checking chlorine and pH every day.

    Chlorine plays an important role in maintaining your pool by killing harmful bacteria.

    pH measures the balance between acid and alkalinity. If this balance is off, your pool will be a site for undesirable chemical reactions.

    Here are the parts per million levels of properly-balanced pool water:

    • Chlorine: 1 3 PPM
    • Calcium Hardness: 200+ PPM
    • Bromine: 2 4 PPM

    You can measure these pool chemical levels at home using water testing kits purchased from a pool store.

    But its best to ensure accuracy through professional tests at a water analysis centre, which are run by many qualified pool companies.

    Best Ways To Test Pool Water

    The two most popular ways of testing pool chemicals are pool test strips and pool testing kits. Whether you use a kit or a strip, it should measure chlorine and pH levels. These measurements show two of your pools most important chemical readings.

    Its best to find a kit or strips that also measure total alkalinity and total hardness. Total alkalinity can negatively affect your waters pH. Unbalanced total hardness can cause damage to pool surfaces and equipment.

    As you conduct pool water testing, track the chemical levels. Use a journal or logbook to write down the data from each weekly test.

    There can be quite a lot that goes into making sure your home pool is looking and feeling great year-round. However, one of the most important aspects of pool care has to be testing water chemistry, such as the chlorine, pH and total alkalinity levels of your pool!

    There are many ways you can go about this, but the most important thing is ensuring that youre getting accurate results from your tests. Here, we take a look at the whole process and what you should be looking out for when water testing your home pool.

    How To Read Your Test Results

    Each test strip brand may be slightly different. The following explains how to read pool test strip results for Clorox® Pool& Spa Multi-Use Smart Strips and 6-Way Test Strips. For all other strips, refer to the product label instructions.

    Total Hardness: Total Hardness measures the amount of calcium and other minerals in your water. Having water either too hard or too soft, combined with other balance factors, can damage pool equipment and surfaces. Maintain Total Hardness between 175275 ppm.

    Total Chlorine: Total Chlorine is the amount of chlorine in your water, including free available and combined chlorine. Maintain Total Chlorine between 14 ppm.

    Free Chlorine: Free Chlorine measures the amount of chlorine available to sanitize your pool water, which is necessary to kill bacteria and control algae. Maintain Free Chlorine between 14 ppm.

    pH: pH measures how acidic or basic your pool water is. The measurement is critical to the health of your pool water. Having an imbalanced pH can damage pool equipment, cause swimmer discomfort, and hinder the performance of your sanitizer. Maintain pH between 7.2 to 7.6.

    Total Alkalinity: Total Alkalinity and pH are closely related. A low total alkalinity may cause fluctuations in your waters pH and exacerbate low pH. Having highly alkaline water can cause pH to drift upwards. Maintain Total Alkalinity between 80150 ppm.

    Do I Need To Test For Phosphates

    Honestly, I’ve cleared up over 700 green and nasty pools, most times in under 5 days, and I’ve never tested for phosphates. In fact, I’ve never used a phosphate remover on any of my customer’s pools and they always come out perfectly balanced and crystal clear.

    Phosphates are a food source for algae, but they’re not the only food source. Phosphates in your pool, unless they’re at extremely high levels, should pose no issues.

    How To Fix High Iron Levels

    Again, because theyre both metal elements, the same remedies to fix high copper levels will also work for high iron levels.

    You can use a metal sequestrant, which wont remove the iron, but will keep it from rusting and staining your pool. Just remember sequestrant will dissipate, so adding it must become part of your regular pool maintenance.

    Also, controlling pH levels can help control iron levels, so keep a good handle on those.

    Finally, a metal trap filter or a hose filter works just as well for iron as it does for copper. So if your water has turned a yucky brown color due to high iron levels, dont worry. Its fixable.

    Ph Levels Of Water In Your Pool

    How to Use a Pool Test Kit to Check Water Quality

    Another critical consideration when it comes to maintaining pool water quality is the pH of water.

    pH refers to the acidic or basic inclination of water. Maintaining the pH value is essential in pools because it can significantly affect chlorine effectiveness for pool sanitization.

    Chemically, pH is measured on a scale from O to 14, with 7 being neutral. With lower side indicating acidity, whereas the higher side of the scale resonated with alkalic properties.

    As the value approaches 7, both acidic and basic properties tend to neutralize. Here, it is important to note that alkaline should not be confused with the pool waters total alkalinity. While pH and total alkalinity are different, one may be the other and vice versa.

    Ideally, the pool water pH should be maintained within the range of 7.2 to 7.6. Pool water with a pH of less than 7.2 can be corrosive to the pool structure and equipment. It also negatively impacts the ability of chlorine to disinfect water.

    In case of acidic water, you will need larger quantities of chlorine than would be used at normal pH levels. On the other hand, with a pH higher than 7.8, you are more likely to have scaly or cloudy water.

    When the water pH is higher, it affects the water solubility of calcium, resulting in scales and cloudiness of water. Moreover, a higher pH also affects the effectiveness of chlorine for pool sanitization.

    Time Between Sample And Result

    One of the biggest reasons for inaccurate water testing results, besides where you take the water sample from, is time. Leaving your water sample exposed for too long before testing it can lead to inaccurate results.

    Similarly, when using a solution-based test, leaving the final solution for too long can lead to changes in the colour, giving inaccurate readings. Thankfully, simply performing the test as instructed without unintended breaks will remove this issue.
