How to Remove Cloudy Pool Water

Cloudy pool water is undesirable because it greatly affects how your pool looks and it can make guests hesitant to jump in.


Several factors can impact the cloudiness of water, but the main culprit in most cases is hardness. To test for hardness, we recommend getting a TDS testing kit and following the instructions accordingly.


However, let’s first take a look at other pollutants that cause cloudiness and see how to make the water crystal clear again.


Check the Filters


For the most common pollutants, you might need a water filter that can handle chlorine, bleach, and other chemicals.


If your filter gets too dirty, you might need to replace it or clean it with a brush if there’s too much debris. Faulty filters may have issues with their valves and need a replacement for their cartridge.


Whatever the case may be, we recommend looking through your filter’s manual to determine the best course of action. You wouldn’t want nasty chemicals in the same water that you, your children, and guests bathe in.


Check the Chlorine Levels


Sunlight, rain, and other factors can deplete chlorine levels inside the pool, making it more prone to accumulating other pollutants that give it a cloudy look.


Chlorine levels should stay between 1.0 – 3.0 PPM, and you can test this out by using a strip kit that’s capable of showing if the amount of chlorine has dropped below 1 PPM.


Adjust the pH


Get a test kit specialized in measuring pH levels. Acidic water falls below the 7-pH level mark, while alkaline water is above 7.8.


The ideal level would be 7.6, but as a rule of thumb, anything between 7.2 and 7.8 works just fine. Get a device that can increase or reduce the pH level of water accordingly and use it to get rid of cloudy water.

Water Hardness


Now we’re finally onto our main culprit, the one thing that causes cloudy pool water in most instances.


If the TDS testing kit has determined hardness is the problem, there are several ways to solve this issue.


First, you can try using a pool clarifier, but then you might notice that there’s limescale leeching on the pool’s tiles. To remove limescale from tiles, you can use a combination of vinegar and lemon juice.


Is Soft Water Good for Pools?


Now you might think that filling your pool with soft or softened water would be a good idea since water hardness is the main culprit for cloudy pool water in most scenarios.


However, that’s far from the ideal. Softened pool water will seek to balance itself by leeching on the calcium from the pool’s tiles. In short, this will cause grout to dissolve and corrode, making the entire structure look uncared for.


Preventing Hard Cloudy Pool Water


As you can see, the best way to remove cloudiness is to prevent it. And since a water softener won’t work in this context, you’re far better off with a saltless alternative.


Fortunately, you can get the Yarna water descaler to do just that. It works by emitting capacitive electronic signals throughout the pipe so that the water’s calcium and mineral crystals become less sticky.


In short, they will no longer stick to surfaces, cloud the water, or affect pH levels in any way. And because the crystals are still present, the “softened” water will no longer tend to leech on the pool tiles, thus preventing corrosion. You can choose between our CWD24, CWD30, or CWD48 models, depending on your exact needs, pipe size, etc.


Final Thoughts


Cloudy pool water isn’t going to be an issue as long as you take the necessary steps to prevent water hardness and fix your filter to screen out chlorine and other pollutants.
