Adding too many chemicals to your pool can also affect the aspect of the water as the pH, alkalinity or chlorine levels get too high. Not running the pool filter enough during the day or the filter not working properly can also cause the water to become cloudy. Regardless the reason, what matter are the solutions you find.

How to Diagnose It

Now that you are aware of what causes this problem, let’s move on to learning how you can detect whether you are confronted with this issue as well.

If any of these issues apply to your pool, buy a pool water test kit and use it to measure stats such as alkalinity, pH, chlorine levels, and calcium hardness. In case that these parameters are not between normal levels, then you are definitely confronted with cloudy water and you must immediately take action to fix the problem. Otherwise, you expose yourself to a series of damaging health effects if you keep on swimming in the pool.

The Dangers of Swimming in Muddy Pool Water

If you don’t want to spend your entire life treating urinary tract infections that keep recurring, you definitely have to stay away from such water. E. coli is the most common presence in pools that have cloudy water, causing you to become a lot more susceptible to the unpleasant infections.

Therefore, don’t take your chances and avoid swimming in this type of water altogether.

How to fix it

You already know that this is a big problem. Such a problem comes as a result of four things, including the incorrect amount of pool chemicals, poor circulation, faulty pool filtration and environmental factors. It is not easy to diagnose this problem, but now that you the most common culprits you can solve this problem without adding chemicals. Also, you need to take into consideration the fact that all you need to do is to increase chlorine production on your generator. The following steps can hopefully help you fix the problem.

  • Test your Pool Water

  • The most important thing you need to do it is to test your water using a quality pool test kit. Also, you can take it to a local pool store and wait for the results. Sometimes, these test kits can give unreliable results. Therefore, if you own a saltwater pool, it’s recommended to purchase a kit that includes a reliable saline test.

  • Adjust Chemistry

  • Once you have received the results of the test, it is advisable to adjust levels as needed. Hake a look at your pool maintenance information to see if you are within the recommended ranges for things like chlorine, pH, salinity, calcium and alkalinity. After the water is balanced, you can reassess your pool and continue with the next methods depending on your pool’s chemistry.

  • Add a Pool Clarifier to the Water

  • When you look at cloudy water, you see millions of tiny colored particles that make it look blurry. Collecting all those small particles would be impossible unless you can somehow make them larger and easier to collect. A pool clarifier can act as a coagulant and make cloudy pools easier to fix. It would be of great help in keeping your pool clean if you would add a pool clarifier every week. This substance collects the tiny particles that make the water look cloudy and sticks them in larger particles so it will be easier for your pool filter to pick them from the pool. Pool clarifiers can be found in any pool maintenance store and they don’t require the help of a professional since you can add it to the water yourself.

  • Use a Pool Floc

  • Another great solution for fixing cloudy area is a substance called Floc or Flocculant that has a fast result in sending all the tiny particles to the bottom of the pool. Add the pool Floc to the water and let it work overnight and you will wake up to a clear pool water. However, keep in mind that this substance does not help your filter gather the particles because it sends them to the bottom of the pool. The hard part of using pool Floc is just beginning because now you have to set your pool pump to backwash which means it will throw away the water in the pool in order to eliminate the dirt. By vacuuming the water out of your pool, you will keep it from running through the pool’s filter and clogging it. Still, this method remains time-consuming and implies losing a lot of water.

  • What to choose between a pool clarifier and a flocculant?

  • Before using a clarifier it is very important to understand several things. Generally speaking, clarifiers produce coagulation. They bring small particles together in order to form some bigger ones. This allows the filter to catch them easily. On the other hand, a flocculant has the purpose to take all those tiny particles to the bottom of the swimming pool. This way, it will be easier for your to vacuum them out. Although it works quickly, the worst part is that you have to do all the work.

    Frequently Asked Questions

    1What is the optimum pH level for pool water?
    The pH scale goes from 0 to 14, where pH 7 is neutral. However, if the pH is above 7, the pool water is basic, but if it is below 7 then the water is acid. The optimum pH for pool water is 7.4 since this is the same as the pH in human eyes and mucous membranes.

    2 Which tool sould I use to measure and control the pool chemistry?
    You can use a digital pool water test reader or a pool water testing strips.

    3 Which Pool Filter Is Best?
    There are three types of filters: cartridge (paper), DE (diatomaceous earth) and sand. Each has its own pros and cons.
