My Pool Water Is Cloudy Is It Dangerous

Why Your POOL WATER Is CLOUDY (And How To Clear It Up) | Swim University

In a word, yes it is.

Not only is there a higher risk of drowning due to not being able to see struggling swimmers or if someone has fallen in through the murky water, the levels of scary bacteria such as E. coli and Legionella may also be at dangerous levels.

Less frightening, but still nasty is high-levels of chlorine in the pool can cause skin irritations and rashes, and also cause breathing problems for those who have asthma.

When your pool water is cloudy, it is essential that you close the pool until the water ph has been restored.

How To Prevent Cloudy Pool Water:

  • Maintain proper water balance. Chlorine and pH levels should be maintained at 1.0-3.0 ppm and 7.4-7.8.
  • Proper levels of calcium hardness and total alkalinity help to prevent solids from precipitating out of solution.
  • Pool pumps should run long enough daily to filter all of the water at least once, or twice during warmer months.
  • Shower before swimming. Cosmetics, hair and skin lotions, deodorants and other products contribute to cloudy pool water.
  • Super-chlorinate the pool at the first sight of hazy water conditions, before it turns cloudy and then murky.
  • Cyanuric Acid or stabilizer should be 30-50 ppm to help reduce the summer suns effect on chlorine levels.
  • Very Small Suspended Solid Matter

    Cloudy water is also caused by dirt particles that are too small for the filter installed in your pool. There are two solutions. You can install a new filter that has a lower micron rating, which will trap even the finest particles, or you can deal with the problem using a chemical clarifier. A clarifier will cause the fine suspended particles to clump together, so they can be removed by your filter.

    In the end, a properly balanced and sanitized pool is your best insurance against cloudy pool water. An ultraviolet pool sterilizer is a popular choice for pool owners who need to lower chemical usage, improve health and safety, and resolve cloudy pool water with one device.

    Some chlorine resistant pathogens can survive in chlorinated pool. SpectraLight destroys viruses that chlorine cannot.

    Best Practices For Water Clarity

    • Optimize chlorine by supplementing it with either enzymes, secondary systems like Ozone/UV/HDO, or both.
    • Regularly backwash, clean and maintain filters to avoid channeling and other problems
    • If you have cloudiness that is small enough that it’s still passing through filters, consider using a clarifier to bind particles into larger clumps for easier filtration
    • Manage the LSI and maintain good calcium levels. If using soda ash, pre-dissolve in a bucket of water and add slowly, rather than just throwing the powder into the pool directly.
    • When CYA, nitrate, metal or TDS levels get too high, drain and dilute some of your pool with fresh water.
    • Keep phosphates to a minimum to slow the growth rate, and help chlorine stay ahead of reproducing contaminants

    Any pool can have world class water clarity. Why not yours?

    Vacuum Waste Out Of Your Pool

    How to Deal With Cloudy Pool Water

    Your pools main skimmer is located at the top of your pool, helping to clear the upper portion of your pool water. It does not help to collect the cloudy particles situated at the bottom of your pool. Knowing this, we need to help your filter get to those particles.

    Simply hook up your manual vacuum cleaner as if you were about to vacuum your pool, but instead of using it as per usual, leave the vacuum centred at the bottom of your pool and turn it upside down. Now your pool filter will be pulling water from the bottom of your swimming pool and releasing the clean filtered water at the top.

    Iii How To Clear Cloudy Pool Water In 6 Easy Steps

    Heres all you need to do to fix cloudy swimming pool water like a pro:

  • Test your pool water
    • Total alkalinity

    High calcium hardness, high pH levels, and high alkalinity can all trigger cloudy pool water.

    Other types of pool testing kit contain reagents. You add these reagents to your pool water and they turn a variety of colors depending on how much chlorine is present, and also on the pH levels.

    Whichever method you employ, its vital to source your pool water the right way. Ideally, grab a sample from 18 inches below the surface. Get the water sample first thing in the morning before the sun has the opportunity to burn off any chlorine.

    Sometimes, simply adjusting these levels is enough to correct cloudy pool water.

    When pool water is too acidic, add some sodium carbonate and youll raise pH levels. If the pool water is too basic, pop in some sodium hydrogen sulfate or hydrochloric acid and youll lower pH levels.

    You should always use cyanuric acid to protect and stabilize your chlorine levels.

    Why Is The Pool Water Still Cloudy After Shocking And/or Adding Algaecide

    In most cases, your pool water may still be cloudy but FC is fine or high. Cloudy or milky water after shocking is normal, and the water should clear up within an hour or so. Just make sure your pump and filter are running properly.

    If you add algaecide, keep in mind that some algaecide contains copper, which can actually make a pool cloudy. If the cloudiness persists 24 hours after shocking, then it’s possible that you used a poor-quality chlorine shock. In this case, you should take another reading of free chlorine and do the shocking again using liquid chlorine .

    You should also check that all chemicalsespecially pH, total alkalinity, cyanuric acid, and calcium hardnessare within the recommended levels. Remember that calcium hypochlorite chlorine shock and chlorine tablets are not recommended for daily pool sanitization, because they raise calcium, pH, and cyanuric acid in your water. You need to be extra careful when using them, or else these chemicals will get off the chart, causing cloudy water, algae, or ammonia in the long run.

    Finally, debris could cause continued cloudiness in the water even when chlorine level is fine. You can try using a water clarifier to send all the particles to the filter, or you can use pool floc to gather all the debris together and then vacuum it up using a manual pool pump.

    Chlorine Is Too Dilute Or Concentrated

    Adding chlorine to pool water helps to keep your pool safe for swimmingsimple as that.

    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 .

    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. .

    The sun’s UV rays can destroy the chlorine , 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.

    You should test your pool’s levels each day to make sure they aren’t too low or too high!

    If a lot of people swim in your pool regularly, you might need to test the levels more frequently.

    The suggested amount of free chlorine is between 2.0 and 4.0 parts per million .

    Can Too Much Chlorine Cause Cloudy Water

    Is your pool water looking a little dishwater-esque?

    It happens to even the savviest of pool owners, so dont hit the panic button yet.

    It is not unusual to have cloudy water with high chlorine levels in the pool. But while it is possible to have both cloudy water AND high chlorine levels in the pool, the cause of cloudiness is NOT because of high chlorine levels rather, your pools cloudy water is caused by some other underlying issues such as water balance, filtration, algae, or water mold issues. The very first step you need to take in fixing cloudy water is to test your pool water. Once you have your results from your test strip or test kit, read on.

    Total chlorine is high & free chlorine is low

    If your total chlorine level is high, but your free chlorine is low, that means most of the chlorine you have in your pool is already combined into something called chloramines combined chlorine is not available to sanitize your water. As a result, you may not have enough active chlorine to keep the water clear. So, this is a situation where your total chlorine is high and your water is cloudy, but its not the high chlorine thats causing the cloudiness its the low free available chlorine level thats actually making your water murky. In this case, youll need to shock your pool to get rid of the combined chlorine and keep the pool clear.

    What if my total chlorine and free chlorine levels are both high?

    So, what now? How do I fix a cloudy pool?

    Filter Your Pool Water 24/7

    In order for this method to work, you need to keep you pool pump and filter running until the water is clear. Your pool filter is going to do all the work filtering out the tiny particles that are making your water cloudy.

    Dont worry, once the water is clear you can go back to running your pump and filter around 8-12 hours per day instead of 24/7.

    Note: If you have a D.E. filter, your pool will clear faster. DE Filters pick up fine particles. If you have a sand filter, it will take longer because it doesnt have the same filtering power as a DE filter. And if you have a cartridge filter, thats right in the middle between the two other types of pool filters.

    Could It Be Ammonia Or Algae Starting Up

    In rare circumstancesespecially during the beginning of summer when swimming pools are opening after closing for winteryour pool may have severe cloudy water that is difficult to clear. FC and cyanuric acid levels drop to zero or close to 0 ppm, there are very high CC levels, and there is a high demand for chlorine in your water, but FC levels will not rise easily, even after adding a lot of chlorine. If you notice these signs in your swimming pool, you have ammonia and you need to use a lot of chlorine to get rid of ammonia in your pool.

    Early stages of algae make pool water look cloudy and dull. To be sure it is not algae starting up, perform an overnight chlorine loss test , which is done by adding chlorine to pool water in the evening when the sun is down to avoid depleting FC and taking the FC reading the following morning. If FC levels drop by more than 1 ppm through the night, the result is positive, and you have algae starting upand the sooner you get rid of the algae the better. Ammonia and algae come as a result of low FC levels, and the only way to keep them away from your pool is to maintain proper FC levels.

    You Have Problems With Your Pool Filtration System

    Your pool pump and filter need to be running for a certain time each day to keep your pool health strong.

    How long you need to run your filter and pump depends on how big your pool is, how often its used, and the type of filter .

    As a guideline, running the filter for 8 hours daily is optimum.

    Failing to run the filter for long enough can cause the pool water to stagnate. As debris and microscopic particles accumulate, so the pool water becomes opaque and turbid.

    Give Your Filtration System Some Assistance

    Your pool filter is typically situated at the top of your swimming pool. While this helps to remove particles floating to the top efficiently, it doesnt work so well when debris gets captured on the bottom.

    You have several options for improving the efficiency of your pool filtration system. By taking these steps, you should improve the clarity of the pool water.

    • Draining the water: If you have an in-ground swimming pool, you will likely have at least one drain on the bottom. If you occasionally open this up, this will boost the circulation of the pool water so the particles rise from the bottom to the top of the pool. Here, the filter will clear them out efficiently
    • Vacuuming the pool: If you have an above-ground swimming pool and no drains to take advantage of, you can replicate these effects by using your pool vacuum. Place the pool vac on the bottom of the pool in the center and turn it upside down. This will agitate the particles and channel them upwards into the filter
    • Stirring the water: If you use a pool brush, you can help remove some debris from the bottom and push it up toward the surface

    You Dont Use A Pool Clarifier

    How to Clear Cloudy Pool Water
    A pool clarifier collects the microscopic particles that are causing your pool water to turn milky and binds them together to create larger particles that your filter can absorb. Using a pool clarifier after shocking the pool is essential to keeping the water clean and clear.
    In most cases, cloudy pool water after shock is only temporary and will clean up itself overnight. To keep your pool water clear, make sure that the chemicals are balanced and you have a proper functioning filter.
