Increase Your Pool Circulation

How To Clear Up Cloudy Swimming Pool Water

Your skimmer located at the surface of your pool cant get to the debris or cloudy water at the bottom of your pool. To help all of your pool water pass through your filter, you can increase your pools circulation.

  • Position your return jets. Point your return jet down at a 45° angle and all in the same direction. This will help churn the cloudy water up from the bottom of the pool to the top where your main skimmer can get it into your filter system.
  • Use your bottom drains. If you have an inground pool, make sure the main drain at the bottom is on and is pulling water from the bottom of the pool into your filter system. This will speed up filtering and clear the pool water faster.
  • Turn your vacuum upside down. If you have an above ground pool with no main drain, you can hook up your manual vacuum cleaner and turn it upside down at the bottom of the pool to mimic a bottom main drain.

If Caused By Pool Filtration And Circulation Systems

A pool water-circulation system can also be a big problem. If your water cannot circulate properly, it will become stagnant and cloudy. To fix this problem:

  • Ensure that the return fittings are turned to point down, which enables the water at the bottom of the pool to circulate properly.
  • Make sure you are using the right pump size to adequately clean the water.
  • Make sure the filtration system is running long enough. A filter should run 24/7 for the water to remain clean all the time. However for home pools that are not busy, at least 8-10 hours a day might suffice.
  • Remove particles that may be blocking your filter.
  • Ensure that you regularly clean, backwash or replace the DE and cartridge filter medium as appropriate. Cartridge filters usually last 2000 hours and should be replaced every 1-2 years depending on the usage.

Clean The Pool Filtration And Circulation Systems

A poor water-circulation system can also be a big problem. If your water cannot circulate properly, it will become stagnant and cloudy. To fix this problem:

  • Ensure that the return fittings are turned to point down, which enables the water at the bottom of the pool to circulate properly. However, the circulation system will largely depend on how the pool was built.
  • Make sure you are using the right pump size to adequately clean the water.
  • Make sure the filtration system is running long enough. A filter should run 24/7 for the water to remain clean all the time. However, for home pools that are not busy, at least 8 -10 hours a day might suffice.
  • Remove particles that may be blocking your filter. Your filter system continuously cleans the water, and if it does not function properly, the water becomes dirty, cloudy, and may even develop algae. Large particles are fond of blocking filtration systems, especially diatomaceous earth and cartridge pool filters.
  • Ensure that you regularly clean, backwash, or replace the D.E and cartridge filter medium as appropriate. Cartridge filters usually last 2,000 hours and should be replaced every 1-2 years, depending on usage.

Stay On Top Of Routine Maintenance

If you keep on top of maintaining your swimming pool little and often, this will not only keep the water looking crystal clear and inviting, but youll also remain confident that everyone who swims in your pool can do so safely.

Try creating a weekly maintenance schedule so you can take care of the quality and health of your pool without becoming overwhelmed.

Consider the following weekly tasks:

  • Remove all larger debris like leaves from the pool water
  • Run your pool vacuum
  • Brush the bottom and the sides of your pool. This will remove dirt and algae
  • Test the chlorine and pH levels of your pool
  • Check other levels in your pool water as required
  • Use pool shock

So My Pools Cloudy Does It Even Matter

How To Clear Cloudy Pool Water {Step by Step Process}

Uh, yes. It absolutely does matter that your pool is cloudy. And though you might be tempted to, I would urge you not to add some pool flocculent or pool water clarifier and consider the task done. These will only perpetuate the problem, since they treat the cloudiness and not the actual underlying cause of that milky water.

In most cases, a cloudy pool indicates that your chemical balance is way offand that means that the gunk your pool filter is supposed to weed out and/or the potentially harmful bacteria that your sanitizer is supposed to neutralize is largely living unchecked. And thats surrounding you and yours on every swim. Not only is it gross, but its also potentially harmful. The last thing you want is to get sick from your pool. Are you with me now?

Test And Balance Your Water

Because youve removed water from your pool, youll need to rebalance your water chemistry. Test your pool water using test strips or a liquid test kit and adjust your Alkalinity and pH. Once you get those levels balanced, add your chlorine.

Now that youve gotten the cloudy water out of the pool, you can start running your filter system normally .

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 .

High Calcium Hardness In Pool Water

High calcium hardness levels can lead to cloudy pool water. To check your calcium levels, take a water sample to your local pool shop. They can test your calcium hardness levels for you. Concrete plaster pools require a calcium hardness level between 200-300 ppm. For fiberglass pools please contact your pool manufacturer to obtain the recommended levels for your pool.

Why Is My Pool Water Still Cloudy After Shocking

How To Clear CLOUDY POOL Water FAST! | Swim University

The process of shocking your pool requires about 24 hours, so dont expect immediate results. You also want to make sure to use a shock that has an active ingredient of calcium hypochlorite. Big-box stores will often provide a less expensive product that does not contain calcium hypochlorite, but avoid this as it is less effective.

If the pool hasnt cleared up in a couple of days after applying shock, its likely a water circulation issue. If this is the case, clean your filter and make sure it is cycling correctly.

Will Rain Water Make My Pool Cloudy

With a rain storm, any number of contaminants can be washing into your pool acid rain, pollen, insects, tree droppings, dust, sand and even phosphates. Any one or combination of these things in rain can make your pool cloudy. A dirty rainstorm can deplete your chlorine level, making pool water hazy.

Get The Pool Water Tested

A simple glance at the water will tell you its murky and unsightly. But it isnt possible to know whats wrong with it without proper testing. For this, you have to get a pool water testing kit.

With the kit, it becomes possible for you to measure numerous factors likely to affect the water quality. You also get an idea of how to easily balance the water.

When it comes to water testing, you will have two options:

  • Acquire test strips that you will need to dip inside a sample of water obtained from the pool. Use the strips to measure the pH levels, calcium hardness, total alkalinity, and chlorine levels.
  • Obtain a testing kit containing reagents to be added to the cloudy pool water. The water will change colors depending on the pH levels and the amount of chlorine present.

If you establish there is a problem with the chemical levels, pH, or chlorine levels, making changes to these levels will cause the cloudiness to dissipate.

What Is That Black Stuff In My Pool

  • Black algae is the least common and the most difficult to get rid of.
  • It has a very strong defense mechanism and deep roots that make it very hard to remove. It will normally look like small, dark black spots on your pool walls.
  • To get rid of it, you will need to do heavy brushing, vacuuming, and chlorination.

What Makes Your Pool Water Turn Cloudy

Green to Clean: How to Clear Up a Green and Cloudy Swimming Pool ...

Swimming pools certainly are fun to own and use, but they, unfortunately, are not problem free. Cloudy water is one of those things that can be frustrating for any pool owner to have to correct. There are usually four main things that cause the water in your backyard swimming pool to turn cloudy. They are:

  • Low chlorine levels in the pool
  • pH and Alkalinity that are not properly balanced
  • Dead algae, dirt or debris
  • Poor filtration

The best place to start to determine what is causing the water in your swimming pool to become cloudy is to test your pool water chemistry. When you use a test kit to find out the pH and Alkalinity of your pool water, the pH should read between 7.2 and 7.8.

The Alkalinity of your pool water should be between 80 and 120 parts per million. If you find your pH and Alkalinity are out of balance to the low side, thats when a box of baking soda can be your best friend.

Its important to note that you should only use baking soda to increase your pH and Alkalinity if both of them are on the low side after testing your water. If your pH is low and your Alkalinity is fine, then its best to use soda ash to raise your pool waters pH.

Option : Use A Pool Clarifier To Clear Cloudy Pool Water

Using a pool clarifier will help eliminate all the smaller particles that the filter cannot remove. Pool clarifiers gather the tiny particles that pollute the water and bring them together to make larger clumps that a filter can easily pick up. Pool filters cannot always pick up the smallest bits, so clotting them together makes cleaning up easier. When pouring in the pool clarifier, keep the filter running and ensure that your pH levels are good to go.

If Caused By Chlorine Imbalance

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 causing a high risk of algae development.

Balance Your Pool Chemicals

Once the water is thoroughly clean, test the alkaline, pH, and chlorine levels in your pool using a test kit. You can buy them online or take a sample to the local pool store for analysis.

Adjust chemicals like muriatic acid and use a chlorine stabilizer to maintain your current chlorine levels. Here is a guide for some of the recommended chemical balances in your swimming pool:

Problems With Your Pool’s Filter

How To Clear Up Green/Cloudy Swimming Pool Water W/ DE Filter

One of the most common reasons for cloudy pool water is a problem with your pool’s filter. If it’s not working properly, it won’t be able to clear contaminants from your pool effectively. This is why checking and cleaning your filters and replacing them when necessary should be a crucial part of your pool maintenance routine. Remember to clear out skimmer baskets frequently, too.

According to Swim University , you should also make sure your filter is on for long enough each day for the entire pool’s worth of water to pass through it this will usually take at least eight to 12 hours.

Clear out debris from your pool’s skimmer basket regularly

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.

How Do I Clear My Cloudy Pool

1. Balance levels

The first thing that you will want to do is check the levels of pH, total alkalinity, phosphates and calcium hardness and adjust them to the recommended levels as per Snap Pool Balance Chart .

2. Check filter

Check your filter equipment. Backwash or clean if needed. There could also be a fault in the filter that needs fixing. Is the filter medium old and or worn?

3. Oxidise the pool water

If you are not using an Eco-Oxidizer or other oxidising device in conjunction with the Bionizer, then the use of a chlorine-free oxidiser such as Hydrogen Peroxide or an Oxy Shock such as one that contains Potassium Monopersulphate should clear the cloudiness. Also some liquid chlorine may be used. Add to the pool late in the day and run the filter for several hours and the water should be sparkling again by morning. The liquid chlorine used should preferably be unstabilised.

4. Add clarifier

If the water remains cloudy after these checks and tricks, then use a compatible clarifier such as Bionizer Blue. A clarifier collects the smaller particles together so they become big enough to be filtered out of the pool water by your filter. For a Bionizer pool, make sure the clarifier you use is Polymer based and that it doesnt pull metals from the water in your Bionizer pool.

5. Add pool flocculant

Monitoring Ph And Pool Alkalinity

Example of how it should look by RD Architecture, LLC

Your pH levels determine how your pool chemicals will work. Youll need to monitor your pool alkalinity regularly so that you can achieve the right chemical balance. A pH balance below 7.0 is too low. If your pH balance is too low, you will end up with cloudy pool water.

You will also end up with algae growing in your water. You could also end up with harmful bacteria. If your pH levels are too low, youll need to use a pH increaser with soda ash. This will help you to clear a cloudy pool.

Dirty Or Broken Filter

An issue with the hot tubs filter is a common cause of cloudy water.

The filters job is to remove particles of dead pollutants that chlorine/bromine have killed. Cartridge filters have a finite size. Eventually theyll catch too many pollutants and become less effective over time.

The catridges media will catch various debris, but it will also catch oil and minerals, which can drastically reduce its ability to filter.

A damaged filter can also occur and cause cloudy tub water. This can be anything from a tear in the media, to a broken end cap. When the filter has any sort of damage, it wont be fully effective when it comes to keeping the water clean.

Contaminants Like Debris Or Algae

Contaminants, particles, and small debris in your pool can cause cloudy water. This is especially common during the springtime. Early-stage algae growth may also cause cloudy pool water.

SOLUTION: Treat algae in its early stages by cleaning and shocking your pool. Test, balance, and clean your water after a rainstorm or when debris or pollen accumulates in your pool.

  • Treat algae. If you already have visible algae growth, youll need to get rid of your algae problem before you treat your cloudy pool water. Unfortunately, algaecide wont solve the problem. Its better as a preventative measure, not a treatment. To remove algae, youll need to skim, brush, and vacuum your pool. Be sure to bypass the filter by vacuuming on the waste setting. Then, youll want to shock your pool. If you need a step-by-step tutorial on getting rid of algae, check out our guide on how to get rid of algae in your pool.
  • Test, balance, and clean your pool after a rainstorm. Storms can blow dirt and debris into your pool and the rain can dilute your pool water. That means your chlorine levels can drop, which we know can lead to cloudy water. Test and balance your water after a rainstorm and skim, brush, and vacuum the pool as needed. If you need to lower your water level, follow this guide on how to drain water from your pool after rain.
