Dangers of a High or Low Pool Water pH

As a pool owner, you know that there is much maintenance work to be done basically every week. A task that you definitely cannot afford to skip on is to balance the pH of the water, meaning that you have to keep the water’s pH between 7.0 and 7.6, the ideal range being between 7.2 and 7.4. Both lower and higher levels of pH can have serious consequences for your health as the chlorine that you add in the water won’t be able to sanitize it, thus algae and bacteria making an appearance. If you want to learn more about the dangers that you subject yourself to when the pH of the water is too high or too low, check out the following lines.

Dangerous Effects of High pH Levels

  • The water will become cloudy and dangerous to swim in.
  • You will have to put about 80% more chlorine into the water for it to make its effect.
  • Rashes and skin irritations will appear.
  • Your eyes will feel like they are burning when you will swim.

Dangerous Effects of Low pH Levels

  • The metal will start to corrode, meaning that the ladders and rails will be affected, as well as the pipes and the fittings of the filter.
  • Due to the metal corrosion, sulfates will form, forming brown or black stains on the walls of the pool.
  • Chlorine will evaporate at a fast pace, thus not being able to sanitize the water effectively.

What You Should Test the Pool Water For

When you install a pool, you install it for the sole purpose of using it as much as you can when the weather is warm. But simply having a pool in the backyard does not mean that you can automatically use it at all times. The truth is that there is a generous load of maintenance work that needs to be done in order to keep the pool clean and safe for use. Unfortunately, there are a lot of problems that can occur with the water at a chemical level, problems that you need to keep an eye on to ensure that you will swim in a safe water. Thus, it is important to test the water of the pool for certain chemicals and potential issues. To find out what exactly you have to test the pool water for, check out the following lines.

  • The pH Level

  • The pH shows how acidic or basic the water is, if the water is too acidic being an issue as it becomes corrosive to the metal fixtures and it will provoke skin rashes and eye irritations, and if it is too basic being a problem because the sanitizer that you use won’t be effective and the water will inevitably become cloudy. The pH ranges from 0 to 14, and you must make sure that it stays between 7.2 and 7.6 for the water to be at an optimal level. Of course, to test the pH of the water, you must use an effective digital test kit.

  • The Chlorine Levels

  • Chlorine is the most commonly used pool sanitizer, and unfortunately, in most cases, people tend to use it excessively. This actually causes a great deal of damage to the pool’s water, an excessive dose of chlorine being required only once or twice per month, when you shock the pool to kill off any bacteria and harmful contaminants. The ideal level at which you must keep the chlorine in the pool’s water is between 3 ppm and 5 ppm.

  • The Calcium Hardness

  • The calcium hardness represents the amount of calcium present in the pool’s water. If the calcium hardness level exceeds 400 ppm, the water will become cloudy and scaling will occur. On the other hand, if the hardness is below 200 ppm, the water will become corrosive to the pool. Therefore, in order to make sure that the calcium hardness level is in check, it must stay between 200 ppm and 400 ppm.

  • The Total Alkalinity

  • The ideal total alkalinity for the pool’s water ranges from 80 ppm to 150 ppm. The reason why the total alkalinity is a factor that you must frequently test with the help of the swimming pool water test kit is that it directly affects the pH balance of the water. If this total alkalinity level exceeds 150 ppm, the water will become cloudy and scaling will occur.

What Makes a Test Kit Be of a Superior Quality

Although the market for digital pool water test kits is not as competitive as other markets are, the best products being clearly delimited from their competitors, it is still advised that you be well informed when it comes to what a quality test must offer so that you will take a smart decision when it comes to what you spend your money on. In the following, we will show you what a quality test kit must offer for it to truly be of a superior quality, so make sure that you read to spend your money wisely.

  • How Many Different Types of Tests It Offers

  • The amount of tests that the kit offers is the most important aspect to take into consideration, by far. The reason why it is so obvious that this is the main factor to take into consideration is that it shows you for how many different types of chemicals and problems you can test the water. Thus, the more the better when it comes to this element, a test like the LaMotte 2056 ColorQ Pro 7 that offers no less than 7 different tests being an ideal option to go with.

  • pH Range That It Offers

  • Just like with the types of tests that you will get to enjoy, the bigger the pH range that it can test for the better as you are ensured to receive accurate reading regardless of what pH level your swimming pool water boasts. A quality test kit should offer a pH measurement from 0 to 14.0 in order to make sure that no matter what the pH of the water is, the test will be able to determine it accurately.

  • Accuracy

  • Obviously, the accuracy of the test is one of the most important factors to take into consideration as the last thing you want to happen is to spend your money on a kit that offers results that are not close to the truth as all, providing wrongful readings of the water’s pH and other factors. A quality product must have a high accuracy, preferably +/- 0.01 when it comes to the pH reading.

  • Ease of Use

  • A high-quality pool test kit must be intuitive and easy to use to ensure that the person who invests in it won’t have a hard time figuring out how to operate it. Also, the results shown are displayed as fast as possible, preferably under 10 minutes. If you want to make sure that your money will be spent on a quality product, we recommend that you go with one of the tests featured in our top.

Pool water could actually have a range of issues that you might never be fully aware of unless you test it yourself.

Frequently Asked Questions

?Why is the pH value of my pool water important?
If the pH value of the water in your pool exceeds the healthy standard – between 7.0 and 7.6 – you expose yourself to numerous health issues. High water pH could lead to rashes and skin irritations appearing, while low pH affects the capability of chlorine to sanitize the water you swim in. Regularly check the pH level of pool water to ensure it is indeed a healthy habitat for you, and do not take any risks as repercussions are severe.

?Is it better to purchase a digital test kit that allows me to check multiple test factors?
Yes, it is indeed preferable to purchase a test kit that allows you to check for multiple factors as this way, you will be aware of other stats regarding the quality of your pool water. However, note that the only crucial test factor a digital test kit must feature is pH as it impacts your health the most, and fluctuations appear rapidly. Thus, it is the one factor you must keep your eyes on at all times.

?How can I figure out what is the pH accuracy of the digital test?
There is no actual way for you to test the pH accuracy of the product yourself, but rather check what accuracy is listed on the specification sheet of the digital test kit or read helpful online reviews about the kit. If you do not want to take chances, we recommend you choose any of the products listed on our top as they boast high accuracies of +/- 0.01 pH.
