Chlorine kills off bacteria and other micro-organisms which cause unpleasant diseases and health problems like athlete's foot, Legionnaire's disease and ear infections source.
Your pool's chlorine levels will fluctuate based on how many people swim in it, based on the amount of rainfall you receive, and based on the amount of sunlight that shines on the water. Read : how to help when your pool is overflowing with rain. The sun's UV rays can destroy the chlorine source , and lots of rainfall will also dilute its levels, giving microorganisms a chance to multiply, which affects the appearance and safety of your pool.
If the chlorine level in the water is too high, it's also possible for the water to take on a murky or opaque appearance. As the levels drop, due to swimmers using the pool or the sun's rays burning it off, the cloudiness should clear up. If a lot of people swim in your pool regularly, you might need to test the levels more frequently. Your pool filter and pool pump need to run for a certain number of hours daily to do its job properly.
How long you should run the filter for each day depends on the size of your pool, how frequently people use it, and the type DE filter, or cartridge filter. When the filter doesn't run for long enough, the water in the pool becomes stagnant. Bits of debris and tiny particles build up, making the pool water turbid and opaque. Water that's too hard—meaning it has high amounts of calcium in it read how to remove calcium from your pool —is more likely to be turbid than soft water.
High calcium levels don't only make a pool cloudy—they can also cause damage to the pool filter and plumbing , thanks to the buildup of calcium deposits.
When the water is too soft, surfaces can wear down or corrode more easily, shortening the lifespan of the swimming pool. Let's not get super technical here, but the pH of your pool water, or how acidic or basic it is, can also cause it to be cloudy or clear. When the water is too basic, meaning it has a pH over 8. But it can spell trouble for your pool, as even a bit of rain can be enough to mess with your carefully calibrated chlorine levels.
Since it's super impractical to suggest that you cover up your pool every time it rains, the better option is to monitor your pool after rainfall. If the water looks cloudy, test the chlorine, pH, and other chemical levels with a test kit, then adjust as needed. If you notice that your pool has a powerful chlorine odor or if the levels of combined chlorine are higher than they should be when you take a water sample, shocking the pool is in order source.
Shocking your pool raises the chlorine to up to 10 ppm, and the super high dose of chlorine leads to the breakdown of dangerous chloramines which are responsible for that distinct "pool" smell. The high level of chlorine also kills bacteria and pool algae in the pool or pool's filter system. In some instances, the cloudiness is a temporary thing source. Running your pool's filter right after shocking can help it quickly clear away the particles and debris that cloud the water.
The condition of your pool's water before you shock it can also play a role in whether or not it ends up as cloudy pool water afterward. For example, if the water is fairly basic, with a pH over 7. To keep that from happening, test your pool's pH before you shock and only use the treatment if the pH is 7.
If you add a product that has a high level of calcium to a pool that is already pretty high in calcium hardness, you're likely to end up with water that's clouded by calcium particles. Your best option, if you have hard water, is to choose a pool shock that doesn't contain calcium hypochlorite.
The quality of this type of product tends to be lacking, mean it leaves a fair amount of undissolved solids floating about in the water. If you are concerned about the shock product you use dissolving quickly or at all , it might be your best bet to choose a product made of very fine particles or even a shock product that is chlorine-free. Although you can clearly see that your pool water is murky, you won't be able to tell what's wrong with at a glance. That's where a pool water testing kit can come in handy.
A testing kit lets you measure a variety of factors that affect the quality of your water so that you can balance your water. You can purchase test strips, which you dip into a water sample to measure pH, chlorine, total alkalinity and calcium hardness. Remember that high alkalinity , high pH, and high calcium hardness can cause cloudy water.
Another option is to purchase a kit that includes reagents, which you add to the water. There are three main causes for cloudy pool water, including poor filtration, chemical imbalances, or environmental factors, like nearby construction, trees, or wildlife.
If the chemical composition of the water is balanced and the filtration system seems to be functioning normally, then the cloudy pool water may be caused by an environmental factor. Construction, severe storms, and large groups of people can dump high levels of dirt, dust, and other debris into the pool water. Trees, wildlife, and algae spores cloud the water with pollen, sweat, algae blooms, hair, feathers, and other organic matter, making it difficult for the filter to quickly clean the water.
However, fixing these environmental issues is typically as easy as adding a pool clarifier to the water. This chemical acts as a coagulant, bonding together the loose dirt, pollen, and other small debris, which increases the size of the loose particles and makes it easier for the filtration system to pick up the particles. After applying the pool clarifying coagulant, it can take up to 24 hours for the pool water to clear up.
Unfortunately, environmental factors, like nearby construction or wildlife, may be outside of your ability to control. If the pool is frequently contaminated, add a pool clarifier to your regular pool maintenance schedule to help maintain the clarity of the water.
The range of pump and filtration problems starts with simple human error and extends to worn-out or broken parts. During the swimming season, the pump and filtration system need to run for at least 8 hours every day to properly clean and filter the pool water.
The jets also need to point downward in order to move the water at the bottom of the pool through the system. Regularly empty the skimmer basket and backwash the pump and filtration system to help prevent clogs. Clear the clog or hire a pool repair professional to clear the clog before restarting the filtration system to avoid further repairs.
If any parts are severely worn or broken, they will need to be replaced. The filter media also can become dirty and clogged over time. It needs to be removed and chemically cleaned with a filter cleaner. However, some people may prefer to replace the filter media.
First, use a pool test kit to test the chemical composition of the pool water. It will always take a few days. Make sure that the pool water is continuously filtered.
This will give you the quickest result. The steps below should help you get the water clear again:. To prevent white or milky swimming pool water, you should check the water quality regularly. In the swimming season this means that after each swim. You can adjust the water quality based on the measurement results.

Cause of milky pool water Milky water is often due to an imbalance in the water. A sudden thunderstorm can also cause poor water quality. Making milky water clear There are no silver bullets for clearing a swimming pool. The steps below should help you get the water clear again: Check the water quality with a good tester.
The pH value is particularly important in this respect. Make sure this value is stable between 7. Perform a chlorine shock as explained in the video below. After the chlorine shock, the chlorine value should be between 1 and 2 ppm. Be careful when adding chlorin e. Too much chlorine can cause adverse effects or damage to the pool.
