Use Pool Water Clarifier

How To Clear Up Cloudy Swimming Pool Water

Finally, you want to consistently add the proper amount of pool clarifier to the water. This will help bind a bunch of tiny particles into bigger particles that your filter will have a better chance of picking up.\

Every pool clarifier on the market is different, so make sure you read the bottle to make sure youre adding the correct amount for your size pool.

Total Alkalinity Too High

Pool water with a high total alkalinity is often associated with cloudiness. This is because it can cause an imbalance in the pH levels and lead to;calcium scaling. Typically if your TA is higher than 200 ppm, youre at risk of a cloudy pool and just like imbalanced pH levels, your chlorine will be less effective.

How To Clear Cloudy Pool Water Caused By Low Free Chlorine

Low free chlorine levels are caused by heavy usage, heavy rainfall , or hot sunny days when UV light oxidizes lots of free chlorine. If you have an outdoor pool, you can use a chlorine stabilizer, such as cyanuric acid, to prevent chlorine depletion as a result of direct UV light. Remember that cyanuric acid is very strong, and if it exceeds the recommended levels, free chlorine will disappear, and the water will turn cloudy and be at high risk of algae growth.

In summary, if your combined chlorine reads above 0.5 ppm, your water may turn cloudy and become unsafe for swimming. If this is the case, you need to shock your pool immediately to clear it.

Liquid chlorine or sodium hypochlorite is the best option for a daily free chlorine boost, because it does not affect pH, calcium hardness, and cyanuric acid in your water, which make pH, calcium hardness, and cyanuric acid scale high above the recommended levelsleading to cloudy water, metal stains, ammonia, algae, and other pool problems.

Failure To Run The Pool Filter

On a normal day, you need to run the filtration system for between 8 to 10 hours. You also need to confirm the filter is working. If you dont run it as often as is required or if you fail to confirm its working as it should, you increase the possibility of getting cloudy water.

The filtration system is intended to relentlessly clean the available water. When it fails, the water becomes stagnant and starts to turn milky in no time.

Check The Filtration System

How to Clear Cloudy Swimming Pool Water

Cloudy water can also be caused by problems with the tubs equipment and filtration system. The pump should be inspected regularly and the filter should be cleaned every 2 to 3 weeks to keep it operating at peak performance.

Heres how:

  • Shut off the power to the tub so you can inspect the equipment.
  • Remove the side panelling on the tub to expose the pump. Check the pump for any leaks , and inspect the impeller to make sure its not clogged. Turn the power back on and check that the pump is pushing water to the tub. Once finished with the pump, turn the power off again.
  • Remove the cartridge filter from its housing. Check it for excess debris and look for signs of damage on the media or end caps.;
  • Hose down the cartridge filter to rinse it of any built up pollutants. If its very dirty, soak the cartridge in a deep cleaning solution for 24 hours to restore it. If the filter is torn or broken, replace it.
  • Place the cartridge filter back in its housing.
  • Reattach the side panelling to the hot tub.
  • Turn on the power and run the tub.
  • Note: If you have a biofilm problem in the tub, no amount of sanitizer and water cycling will fix it. Instead, youll need to add a biofilm cleaning product to the water while running the spa in order to break down the biofilm, as well as anywhere it might be growing in the pipes and filtration system.

    How To Clear Cloudy Pool Water

    • |October 13, 2020

    I hate cloudy pool water as much as I hate cloudy lemonade . Theyre ugly, dirty, and generally not ideal for swimming thanks to a number of potential health risks.

    The worst part? Cloudiness can strike your pool in a matter of hours, leaving you scratching your head as to what exactly went wrong.

    In this article, Ill walk you through the exact steps to identify, clear and prevent a cloudy pool for both inground and above ground pools.

    Need a quick answer? The cause is either chemical imbalance, circulation/filtration issues, or environmental effects. To fix it, youll first want to test your pool chemistry to make sure everything is in balance, then throw in some clarifier or flocculant to clump the debris. Your filter will take care of the clumps and voilà clear water.

    What Happened Reasons For Cloudy Pool Water

    Why do pools get cloudy even after you add chlorine? Primarily for two reasons: first, because of over-shocking the water , and two, because of common debris and other natural contaminants falling inside.

    Cloudy swimming pool water happens because of the same issues:

    • Shocking the water too much or too high, which leads to imbalanced chlorine levels
    • High pH and alkalinity
    • A clogged or broken filter
    • Algae development
    • Debris, bugs, and microbes

    The outdoor environment is naturally destructive to a pool of clear water. Rainwater, bird droppings, twigs and leaves, flying debris, garden debris, algae, bugs, and even the sun can alter the chemistry levels of the pool water.

    When you add chemicals and organics to the water, the appearance and properties change. High levels of pH make the pool cloudy, as does high alkalinity, high chlorine, and high calcium hardness.

    Not only can these chemical changes occur naturally because of outside elements, but even altering the chemistry yourself can give the water a milky and unattractive appearance.

    Check The Filter System

    A cartridge filter, sand filter, or DE filter are the three types you might be using on your pool. Regardless of the kind you have, the filter must be working properly and running for at least ten straight hours every single day.

    If the filter isnt clean, dirt and other particles get filtered back into the pool and make the water cloudy. If you have a pool with a backwashing system, ensure that you are doing this consistently.

    Backwashing cleans out the filter and gets rid of dirty water so that when you turn the filter back on, it works as a water clarifier. If you have a cartridge filter, the best way to clean a cartridge pool filter is to do it regularly. Keep up on cleaning the cartridges as much as possible so that the algae doesnt go back into the pool.

    Can You Swim In A Pool With Cloudy Water

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

    If you suspect that the cloudiness is caused by a lack of chlorine, avoid using the pool until the water has cleared. The bacteria and algae causing the cloudiness in the water can be harmful if ingested and can make you sick.

    If your water does have a good chlorine level however you can most likely swim in a cloudy pool. If the pool has a chlorine level above 1ppm the cloudiness is almost always related to filtration or poor water balance. In this case the cloudiness is caused by harmless minerals and other fine particulate.

    Why Is My Pool Water Cloudy After Opening A Pool

    Depending on how carefully you closed the pool for the winter, at the beginning of summer, you may see algae and cloudy water.

    The main cause is usually imbalanced chemicals. If your water is free of algae, all you need to do is test for all the chemicals and adjust. Starting with the pH, then the chlorine, and then other chemicals after that.

    If the water still appears cloudy after adjusting all the chemicals, you can try using either water clarifier to remove the debris through the filter or use pool flocculant and then vacuum to remove any particles.

    Can You Use Baking Soda To Clear Up A Cloudy Pool

    NO! Baking soda is a base and will hugely increase the level of pH, which actually causes the water to turn cloudy. Some people may suggest using baking soda as a quick fix if alkalinity is high, but it is not a reliable pool chemical. Chlorine should be the only substance used to clear a cloudy pool.

    Some Final Tips On Keeping Your Pool Water Clear For Good

    Clear Up Cloudy Swimming Pool Water | Short Version

    To keep your pool looking flawless all year round, remember these tips:

    • Deep cleaning can prevent cloudiness from starting, even in the beginning, when the water first loses its sparkle
    • You can also keep the water looking fresh by stirring it and skimming for debris or manually using a pool brush to push the particles in
    • Regularly shocking your pool;cleaning the filter regularly by backwashing will go a long way in preventing cloudiness
    • You can also anticipate cloudiness by taking a pressure gauge reading and backwashing whenever the pressure reaches 5-7 pounds per square inch above regular readings

    Remember, keeping a pool is an art project as much as it is managing hardware. Clean the area regularly. Be aware of the most common threats that change the waters properties.

    Keep up to hygiene codes for family and friends, and use all the latest appliances to keep up constant monitoring and maintenance. If you take the time to keep your pool looking beautiful, it will sparkle and look as clear as glass!

    Using The Bottom Drain

    The pool skimmer is at the top of your pool and doesnt help collect the particles that sit on the bottom. Getting those particles at the bottom of the pool is just as important as those at the top.

    You have to help the filters suck up those particles, and the best way to do that is to constantly stir up the water or turn on the bottom drains.

    Every inground pool has one or two bottom drains. The filter system uses these to pour water from the bottom of the pool and circulate clean water to the top.

    If you already tested your water chemistry and utilized the pool shock, this might be the next best option.

    Prevent Dilution Before It Occurs

    The best way to keep your pool water clear is to prevent rainwater from diluting it in the first place. Keep an eye on the weather forecast during swimming season and pull the pool cover in place before any storms settle in over your region. A good quality pool cover is a worthy investment, as cheaper models made with lightweight plastic vinyl are more likely to tear over time and allow the rain to infiltrate the pool. If you dont have a pool cover, you can get a head start on cleanup by adding algaecide to the water and sweeping away any debris in the vicinity of the pool before the rain arrives.

    Whats The Difference Between Tablets And Liquid


    Both the liquid and tablets work in pretty much the same way. With the liquid clarifier, youll need to measure out the amount needed since its in liquid form. Clarifier tablets are easier in a way since you do not need to measure anything. Just drop in the required number of tablets.An added feature is some clarifier tablets are slow-release which means theyll keep clarifying and continuously treat your water.

    Why Is My Pool Water Cloudy

    When contaminants enter your pool, your sanitizer starts attacking them. But when there are too many contaminants to fight or the contaminants are too large, youll end up losing sanitizer quickly. And without enough sanitizer, pathogens and bacteria will grow in the water.

    The cloudiness comes from small particles in the water that reflect light. These particles can be introduced into the water by the environment, humans, and chemicals, or can be the leftover particles of evaporated chemicals.

    Cloudy pool water is not only harmful to your pool filter, but it is also dangerous to swim in because it can be full of harmful bacteria, such E. coli and Legionella, and it is a drowning hazard.

    Here are the most common causes of contaminants entering pools and making the water cloudy.

    Human Causes

    Unless you shower right before jumping in your pool, youll likely introduce contaminants into the water. These contaminants include sunscreen, beauty products, sweat, and urine. And its these human contaminants that require you to keep adding sanitizer to the water.

    Environmental Causes

    Sunlight causes sanitizer levels to deplete quickly in pool water. When you add chlorine to your pool water, the ultraviolet rays of sunlight break down the hypochlorite ions of the chlorine, causing them to evaporate into the air instead of sanitizing your pool water.

    Chemical Causes

    Excessive amounts of pool chemicals can cause cloudy pool water. These include:

    More Pool Cleaning Tips

    • Chlorine comes;stabilized or unstabilized. Stabilized chlorine is coated with Cyanuric acid to prevent;Cl2 from evaporating. Unstabilized chlorine, such as sodium hypochlorite, is not treated with Cyanuric acid.
    • Sodium hypochlorite, also known as pool bleach, is available as a liquid and is highly concentrated compared to household bleach. Calcium hypochlorite is available as a granular powder or slow-release tablets. Both of these chemicals are used to shock the pool in order to raise the concentration of free chlorine in the water.
    • Calcium hypochlorite reacts vigorously with water to release free chlorine; but it dissolves slowly. To get the most free chlorine into the water, add it to your pool at night so it wont evaporate as quickly. Youll need to wait 8 hours to use the pool, anyway. The calcium acts as an alkaline buffer.

    When in doubt, consult the instructions that came with your pool, or schedule an appointment with a professional to resolve any questions and ensure that your pool provides a clean, safe and relaxing environment for you and your family.

    First You Need To Test Your Levels

    The first step to clearing cloudy water in a pool is to determine why it is occurring. Chemical testing is therefore required to solve the problem. Taking any standard pool testing kit, whether in strip form or using liquid reagents, and determining both your pools pH as well as sanitizer levels will give you the first clue as to why cloudiness is presenting in the water.

    Consider Draining And Refilling

    How To Clear Up Green/Cloudy Swimming Pool Water | Short Version

    If youve tried the above fixes and the water is still cloudy, its best to start from scratch by draining and refilling the tub.

    Heres how:

  • Add a line flush product to the tub. Let it circulate for 30 minutes so it can make its way into the filtration lines and remove any debris that may be growing in them .
  • Turn the tub off and begin the drain. You can attach a garden hose to either the drainage port at the base of the tub, or to a submersible pump placed in the tub. The submersible pump takes around 15 minutes to drain whereas using the drainage port can take 1 to 2 hours.
  • Ensure the hose is running the waste water to an area where its safe to dispose of. This is usually a storm drain or sewer, but check with your citys ordinances so you arent unknowingly breaking the law.
  • While the tubs draining, remove the cartridge filter from its housing and rinse it off. If its considerably dirty, deep soak it for 24 hours. If its damaged, replace it.
  • Once the tubs empty, scrub it down using a spa cleaner and a non-abrasive sponge. Rinse it thoroughly so no leftover suds get into the hot tub.
  • Replace the drain plug at the base of the tub, and fill it up using water from your garden hose. For superior water, invest in a garden hose pre-filter. This attaches to the hose and filters the water source, so your tub starts with high-quality H2O.
  • Test the water and add in the necessary chemicals to balance the tub. Turn the power back on and circulate the water for an hour.
