Filtration problems. Usually, running the pool filter for at least eight hours a day is ideal. So be sure your filtration system is running on all cylinders. Too much calcium. How hard the water in the pool is can also influence whether it's crystal clear or murky.
Having water that doesn't have enough calcium can also be an issue. If the pH is too low, less than 7. Having a low pH can cause damage to the lining of the pool, causing it to wear away.
Debris and particles from the corroding lining can cloud the pool's water. Lots of rain. Rainwater might seem like it's the purest type of water out there. Excessive rainwater can also muck up the balance of other pool chemicals in the water. In The Swim Chlorine Pool Shock - 24 X 1 Pound Bags Powerful chlorine shock treatment that is great for regular maintenance Quickly eliminates algae, bacteria, and other harmful contaminants from your pool water.
Sometimes, the best way to correct issues with the water in your pool is to "shock" it. An undesired aftereffect of shocking your pool is this: it can cause cloudy pool water. Having hard water in your pool can also present a problem when you go to shock it. Calcium hypochlorite shock products might not only be an issue for you if you have hard water. How to clear cloudy pool water. Alright, now that we know what we're dealing with, let's get to how to fix cloudy pool water.
Get your water tested. Usually, you have two options when it comes to testing your pool's water. Use a pool clarifier. Read : How to choose the best pool clarifier. Use pool floc. Switch the filter pump off and wait for up to 48 hours. During that time, the particles that are making your pool cloudy should clump together. Instead of moving through the filter, though, they will gather on the bottom of the pool.
To clear the water, you should use your manual vacuum to vacuum up the clump of particles. Help your filter out. Clean or replace your filter. The more debris and particles build up on a filter, the harder it needs to work. Eventually, the filter can become so clogged that it can't do anything to clear your pool. We recommend using a commercial filter cleaner at least twice during swim season.
Regular maintenance. Routine pool maintenance should include:. Bottom line. No one wants to dive in or swim in a pool that's so cloudy it's practically opaque. Also, if using tablet chlorine to shock your pool, you need to watch both chlorine and Cyanuric acid level because tablet chlorine will hugely increase your stabilizer levels in water.
I recommend you use liquid chlorine to sanitize your pool because it won't raise levels of Cyanuric acid in your pool. Question: My pool is cloudy, chlorine and pH levels are fine and I have changed the sand just yesterday. What could be the problem?
Answer: Try using pool flocculant then vacuum the pool to remove any particles that might be present in your water. Question: I have shocked my grandkids pool, it holds gallons of water, but the water is cloudy. What do I do next? Answer: Check out your chemicals readings, especially Chlorine, pH, Alkalinity, and Calcium hardness and ensure that they are all balanced. Low chlorine level is the primary cause of cloudy water. Firstly, ensure that pH is stable between 7. If all the chemicals are balanced, but water is still cloudy, there might be fine particles inside the pool, and you need to use a clarifier or pool flocculant and then vacuum up the pool.
If all do not work, try backwashing your filter since it might be clogged. Answer: Low calcium hardness CH is not associated with cloudy water but it causes damage to pool parts, especially to plaster, vinyl liners, grout in between tiles, metal rails, and concrete around the pool. Your water may appear cloudy though as a result of corroded plaster or cement. You need to raise your CH as soon as possible to avoid damages that might cost you a lot to repair. Question: I super shocked my pool after putting in 4kg of alkajuster and now the pool is cloudy.
Will it clear on its own and how long will it take? Answer: If sure all chemicals are balanced, you can try using poolfloc to collect any debris at the bottom your pool then vacuum the pool. Question: Our pool has turned cloudy blue and can't see bottom after adding soda ash, it's been 48 hours and has not cleared up. Tried backwashing etc. Pool people recommended a bag of balance pack for low ph. Post this they still can't register a ph level.
What do you think? Answer: You don't need to add soda ash in a cloudy pool. You need chlorine to clear chloramine by raising FC level to at least 3pp and maintain it there. Blue or greenish colour might indicate green algae and if so, you need a lot of liquid chlorine preferably in order to kill algae. Answer: First, you need an accurate test kit to measure your total chlorine and free chlorine. Total Chlorine is the sum of combined and free chlorine. In most cases, your total chlorine and free chlorine should be same or close and the wider the range, the more your combined chlorine will be, which makes your pool appear cloudy.
So when balancing free chlorine, make sure it reads 3ppm, which means your combined chlorine noneffective chlorine should always be 0ppm or slightly above 0ppm but not more than 0.
In short, just make sure your free chlorine is always 3ppm by taking readings daily and adjusting it to 3ppm. You can use liquid chlorine for daily shocking, and Calcium hypo chloride for cloudy and algae infected pool. Question: I added citric acid to my pool to remove a stain. I realized later that was a mistake, since it eats up chlorine. How do I get out of this trouble? Answer: Leave the pump running for a day or two for the citric acid to be used up, then balance the pH and chlorine starting with the pH.
We have been cleaning the filter daily. We added shock treatment, Muriatic acid, clarified, phosfree two bottles and a bottle of mineral and stain control, Not all at one time, but following instructions, our pH is low, and our pool is cloudy.
There is no algae. What do we do now? Answer: Balance the pH first to be between 7. After Balancing pH, add liquid chlorine in the pool and make sure free chlorine is stable at 3 pmm; cloudiness will disappear only after you balance chlorine.
Answer: Yes, you can use pool floc in a pool with any type of filter. Pool floc collects debris and dirt at the bottom of a pool and you need to Vacuum the pool to remove all the debris after using pool floc.
Question: Our pool was completely clear. We had to get a new furnace. The chemicals are all where they need to be but the pool got really cloudy. What can we do to clear it up? Answer: Try using poolfloc and vacuum the pool, you might be having debris in your water. You need to lower stabilizer first. I am sorry but the only way to lower cya is by draining and refilling the pool.
I suggest you stop using stabilized chlorine to shock your swimming pool since they add cyanuric acid in your water. Thank you for the reply. I'm confused about the Cy Acid as it seems to be in range 30 to according to my local pool store and my last two readings are and Also, I had my pool refilled just last July so the thought of refilling, even partially, is quite upsetting.
For reference I have a 23, gallon pool, vinyl liner. You also need to raise your calcium hardness as it's too low, it should read between ppm and ppm. Hi Rob, the problem seems to be high Cyanuric acid level, the higher the stabilizer level the more chlorine you will need to clear cloudy water. Lower the Cya level to read between 40ppm to 60ppm by draining and refilling a portion of your pool water.
High phosphate levels also contribute cloudy pool water. Get phosphate remover and lower phosphate levels in your pool. As a follow up to the below I had my water tested again on Monday and gave the cartridges a thorough hosing off this morning. They were pretty dirty. Unfortunately, the pool seems even cloudier than the previous days. I did use a clarifier Monday evening which didn't seem to do much but I probably should've cleaned the filter cartridges before hand I just cleaned them today.
Any thoughts? Hi, after heavy rains from the hurricane last Wednesday my crystal clear pool is somewhat cloudy - ie. Immediately after the storm I fished out several branches, lowered the overall water level, vacuumed and cleaned out the filter basket. I have noticed I am getting green algae staining along the walls and deep end floor which seems a bit odd as the pool is properly chlorinated.
It does easily brush away but seems to come back quickly. The only way to lower your Cyanuric acid Cya without causing more chemical problems in your pool is to drain and refill a portion of your pool water. After lowering Cya to recommended level, start by raising pH and TA to their recommended levels, then add chlorine to raise FC to 3ppm.
Best way to lower Cyanuric acid levels. It is reading high. Some say drain your pool, buy cyanuric acid granules, or wait for a heavy rain lol. When all chemical levels are fine but your water is still cloudy, that means you have debris in your water that is coming in due to faulty pool filter that needs backwashing or replacement of filter media.
Try backwashing your pool filter or replace the filter media ie filter sand or D. E filter media if you have not changed it for more than years. You can then use pool flocculant to collect the debris at the bottom of your pool and then vacuum the pool properly to clear all the debris. I don't think the problem is coming because of the vacuuming machine, your filter might be the problem allowing debris into your pool.
Try to backwash your pool filter as it might be clogged, or change your filter sand or D. E filter media if worn out and has not been changed for more than 5 years.
Jim, free chlorine level is too low in your pool and you need to raise it to 3ppm before you get algae or ammonia in your pool.
We recommend using liquid chlorine sodium hypochlorite to shock a swimming pool to avoid raising Cyanuric acid levels without knowing. Remember to maintain your Cyanuric acid level between ppm before adding non-stabilized chlorine. PH no is 7. My filter run about 8 hours a day. What is your Free Chlorine and Cyanuric acid level in water? If they are all too low and you have been using a lot of chlorine, you may be having ammonia in your pool and you need a lot of liquid chlorine to clear it.
To clear ammonia you need to reach high levels of FC above 10ppm and maintain that level by topping up chlorine when FC drops 3ppm. If it's not ammonia then it could be your filter that needs replacement of filtering media i. E filtering agent. I did resurface of my pool and i followed all the instruction in running the pool pump for the first 72 hours after filling my pool with city water and all the chemicals required by the pool guy and changed the filter and clean it almost daily and brushing the pool twice a day now is almost 21 days passed for this procedure and still getting cloudy water can you help thanks.
What is your Cyanuric acid level? If Cya is also low, you could be having ammonia in your water. To clear ammonia you need a lot of liquid chlorine. Liquid chlorine is recommended because it will not raise your pH, Calcium Hardness, and Cyanuric acid levels like granular or tablet chlorine.
Repeat the process of testing FC after 15 minutes and raising it back to 10ppm until FC settles between ppm to be sure your pool is free of ammonia. Leave your FC to come down to 3ppm then raise your Cyanuric acid to 40ppm for non Saltwater pool and 70ppm for Saltwater pool. I have Very Cloudy Pool Water. My PH level is normal at 7. What is the remedy to clear the water. Thank you for your help. First of all, I will recommend you use liquid chlorine sodium hypochlorite which won't raise your pH.
I can see you have very high pH level and Calcium hypochlorite is most likely the cause of that pH scaling. High pH will make your chlorine less active in killing bacteria and algae and will make your water appear cloudy and dull. I recommend you use pH minus to lower your pH to around 7. Opened my pool this year with a foot of clear water and a floor covered in algae. The water got cloudy. Assumed dead algae. Have vacuumed it a number of times, pH is currently 7.
Recently tested very high for phosphates. They gave me 2 bags of shock, said 12 hours after shocking to dump in a bottle of Pool Complete which would cause phosphates to drop to the floor of the pool, then vacuum to waste. It's been around 36 hours since dumping that in and no change. Cloudy water, can't see the floor. New media zeobryte in sand filter last year. White water through the returns may happen because of the air in the tubes and that shouldn't be a big problem since that is normal.
Air gets pulled in through the skimmer, goes through the filter, and back out to the jets where it makes those white colored water. Also, if the stuff coming back in the pool is sand, your filter might be faulty and you need to check that your filter is not releasing sand into the pool.
White film on top of the water that I can't dip out with net. NB: The right amount of chlorine shock to add in a swimming pool: For liquid chlorine or Sodium Hypochlorite with For Calcium Hypochlorite or powder chlorine, add 1 pound for every 10k gallon pool.
In case of algae, triple-shock the pool by adding 3 pounds for every 10k gallons. Only use Sodium Hypochlorite for pool sanitization, and Calcium Hypochlorite for fighting pool algae.
Hello Shonnel, using baking soda in a swimming pool is not a good idea as it has a lot of side effects like affecting pH and Alkalinity at the same time and at a different rate. Instead, you can use pH plus and Alkalinity increaser to raise pH and Alkalinity respectively and Muriatic acid to lower both. Hello Ann, the problem might be with the chlorine shock you are working with; try using plenty of liquid chlorine to shock the pool.
Also due to the heat, free chlorine must be eaten up at a higher rate and you might need a chlorine stabiliser cyanuric acid to help keep chlorine in the water longer. I went to my local pool store I have a 16' x 16' x 48" above ground, 6, gallons to find out why it was cloudy I live in Vegas.. I was told it had no chlorine and I have 2 3" tablets in it at all times. I was told to add a bag of shock and that every other reading was perfect.
I did that and the next day added a line of clairifier then vacuumed the pool the next day. I went back 3 days later cause it was still cloudy. He took another reading and said NO chlorine and I need to add shock every 3 to 5 days.
Kept pump running all night and was told all I would have to do the next day was clean the filter and it would not be cloudy. I went out at am and pool is still cloudy. I pulled the filter cartridge from pump GPH and it was like new, nothing on it.
Why is it still cloudy? Yes Aquamahn, the post worth reading to keep away cloudy water and have a trouble-free pool in the summer. Hi Ginger, please take accurate readings for other chemicals in the pool especially the alkalinity, calcium hardness, and any stabiliser you are using and make sure they are all balanced before adding chlorine.
Chlorine will not balance until all chemicals are balanced. I have an in ground concrete pool that has a painted surface. The ph is 7. I have been battling with this for a month now. Hi Chrissy, you are not doing anything wrong, just keep vacuuming the pool till all the sand are removed.
Also make sure your chemicals are all balanced all the time to avoid pool problems like cloudy water and algae. My pool water is cloudy and i have been doin everything right. I found out that one of my kids through sand in my pool. So I been vacuuming making sure the filter is clean I have good levels. I just dont know what else to do can someone help me figure out what i need or if im doin something wrong.
Hallo Teresa, to reduce the pH, you need to add pH reducer into the pool. Unfortunately, for Calcium Hardness to be reduced, the pool has to be partially drained and replace with fresh water. Hallo Smith, confirm that all chemicals in your pool are well balanced especially Chlorine, pH, TA, and Calcium hardness. Again, runoff water which sometimes carries phosphates and nitrates into the pool might be the cause of the persistent cloudy water, so try testing for these substances.
However, if you just opened the pool recently, don't mind as the water will eventually clear up as you continue maintaining the chemicals in the water. On another though, make sure that there are not debris in the pool since pool floc works only when there is dirt in the water. Finally, your filter might be clogged, try backwashing your filter so that you can be sure it's not the filter.
Hi Sam, if chlorine level is OK, the cloudiness could be as a result of small debris. Try pool flocculant and then vacuum the pool. Hello, I have a 30, gallon in-ground pool with a liner. We had it opened a couple of weeks ago. We purchased new filter cartridges 3 days ago and have been cleaning them once a day. The water levels seem balanced.
The water is still cloudy - blueish color. When the company came to open the pool, they added 25 alkalinity as well as 25 calcium. I have used clarifier as well. We have a variable speed pump - we have been running it at RPM for 24 hours per day for the past 3 days. What can i do to clear it up? This is kinda a hard job being that it's a Well and you cannot drain the water and replace with a fresh one. The only option for you is to saturate the Well water by adding a strong acid like Muriatic acid as directed; while this will not directly reduce the Calcium levels, it will balance the water and take care of the hardness caused by the Calcium.
Good luck! Hi Rupra, the cloudiness must be as a result of insufficient chlorine in the pool. Test for Chlorine and ensure that it is 3ppm. Also measure for all other pool chemicals like pH, Alkalinity, Calcium Hardness and see that they are all balanced.
If chlorine and all other chemicals are balanced but the pool is still cloudy, try using pool clirifier and then vacuum the pool as the white substance at the bottom might be particles or dirt accumulated when people are swimming. Hallo Tammy, the first step you should take is make sure that your pH remains stable between 7. Try using a stronger pH plus so that you can get the pH higher faster. After the pH is stable, take the reading for chlorine and make sure that total chlorine is reading 3 ppm and not less.
Chlorine level cannot stabilize unless your pH is stable so work on it first. The cloudiness is always due to low chlorine levels. I am new to pools. I have a 30k gallon built in pool that has been cloudy for several days. I took a sample to the local pool store and the only level off was a low PH below 6.
I purchased GLB up because the PH was low and I'm not sure how long it takes to work or how to know if it's even working. I don't know what my next step should be because it doesn't look like any changes habe occurred. Thank you for your response!! It was very prompt I think! I have not heard of this so I will definitely give it a try! Hi Katertater, phosphate remover may just reduce phosphate levels in your water but will not clear up the cloudiness.
There must be another course of the cloudiness may be pH or alkalinity levels if not chlorine. If all chemicals are OK but your water is still cloudy, you will have to try pool floc to collect all the particles at the bottom of the pool first and then vacuum the pool, or use pool clarifier which will remove all the particles through the filter.
High level of phosphate means your water has some foreign bodies like dirt, body lotion, hair products etc etc that needs to be removed. Finally, continue adding chlorine shock after using pool floc or clarifier and run your pump high for 24 hours and you will see some change. Sorry for the late response though. I have an above ground 24 ft round gallon pool. Up until about 2 weeks ago the water has been crystal clear.
We maintain out pool very well. My husband tests it everyday and adds chemicals when needed. We have backwashed the pool, vacuumed the bottom, shocked it and it is still very cloudy. Took a water sample to out local pool place and they tested the water and all levels tested perfect. Chlorine was a little high but all the other areas was great.
They did a phosphate test and we have a high level of phosphate. Purchased phosphate remover yesterday, poured the whole bottle in the pool as told and used two bags of shock as told and today the water is still cloudy. Even more cloudy then yesterday. Can't see the bottom of the pool. I don't know what else to do and really want the pool nice and clean for Labor Day weekend. Hi 4boymomrealness, a light green color means your pool is developing algae.
An algaecide should make some changes, however if you notice no change, you will have to use a little of liquid chlorine to shock that pool until it clears up and do it fast before algae gets too much: Add 1 pound of chlorine to your gallon pool and watch it for a few hours as it clears up. The pool is not safe for swimming until the green color and cloudiness clear up.
Hello, all of my chemical readings in the pool are at almost perfect levels and my pool is still super cloudy. I went to my local pool place, and they said try algae cleaner, did that, scrubbed and vaccumed bottom and sides.. Still really milky light green color. Click here to see all of the filters in our collection. Now if you have a Sand Filter, these are the questions that you have to ask:.
If it's been a few weeks or months between back washes depending on the usage of the pool your sand filter could be due for a good backwash. The general rule of thumb is to backwash once a fortnight. Chances are, you'll notice that the water that comes out of your filter during the backwash is very brown and dirty. This means that you should be doing it a little more often!
Let the backwash run for 2 minutes or until the water turns clear. Set the handle back to filter and you're good to go. Filter sand lasts for anywhere between five and ten years.
Pool water clarifiers are a good quick fix, but they should not be used if you have a cartridge filter as it will clog the paper pleats, leaving you needing to replace your cartridge filter element. Pool clarifiers work to gather the tiny particles that have made your pool water cloudy, bringing them together to create bigger particles that will be easier for your filter to pick up.
They are a form of a coagulant. Most swimming pool chemical retailers will carry more than one form of swimming pool clarifier. Confirm if the chemical is a coagulant and you will be well on your way to a crystal clear swimming pool. Again, flocculant should be avoided if you are using a cartridge filter as it will clog the paper pleats. You can use it in an emergency, but be prepared to replace your cartridge filter element in the weeks to come.
Let's say you have a pool party tomorrow and your swimming pool is cloudy. By using pool floc and a little extra work on your part, you can clear your cloudy swimming pool overnight. Pool flocculants work by gathering all the particles that are making your pool water cloudy and sending them to the bottom of your pool, creating a cloud of particles on the floor of your pool.
Unlike a water clarifier, this chemical will not help your filter trap the particles as they settle at the bottom of your pool. Once the particles have settled, you will need to manually vacuum them out of the pool using your pool pump instead of an automatic pool cleaner. The idea is to vacuum the cloudy water right out of your pool, as putting that much dirty water through your filter will not work, sending the dirty water right back into your pool.
You will lose a fair amount of water from your pool, so be sure to keep a fresh hose of running water in your pool during vacuuming. A manual vacuum must be used for this process. Automatic pool cleaners will not work and will end up blowing the larger particles formed at the bottom of your pool, right back up.
It is a difficult process and a lot of water is wasted, but it will clear your pool in 24 hours if done properly. 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. Number one, checking your filter, is the clear winner in our eyes. Having a good quality filtration system and staying on top of cleaning your system regularly will help you to avoid cloudy pool water.
