How To Fix A High Swimming Pool pH Level Problem

If you think your pH levels are off, chances are youve already checked the pool chemistry to make sure. If not, go ahead and check them now to see exactly how far off the pH is.

Ideal pH levels are between 7.2 and 7.6, with 7.4 being optimum.

So if your pH measures anything below 7.2, you need to take the steps to raise it.

Low Stabilizer In Pool: How To Fix A Common Issue

Low stabilizer in a pool is a common issue that can be easily fixed. When a pool is exposed to sunlight, chlorine breaks down and no longer sanitizes causing the sanitizer to be low. This happens quickly and on sunny days the chlorine level can go down to an unacceptable level in a matter of hours.

The following article will teach you about the benefits of using stabilizer as well as how to increase the pH along with the right products to use to do so. You will be on your journey to a clean and healthy pool in no time.

Common Problems With Pool Ph And Total Alkalinity

Now that you have a basic understanding of how Total Alkalinity and pH work together, lets take a closer look at how to resolve specific balance issues in your pool. Weve said it before, but well say it again when making any adjustments to your waters chemistry, ALWAYS read and follow product label instructions, and only add balancing chemicals to the pool if the pump is running. Start with an accurate pool water test to ensure youre dosing the pool correctly. And remember: its far better to make small, gradual adjustments than it is to make large changes. Keep on top of pool water chemistry with regular testing 2-3 times per week.

Reducers To The Rescue

Fix a Green Pool In 5 Easy Steps

To bring down pH, use a made-for-pools chemical additive called pH reducer . The main active ingredients in pH reducers are either muriatic acid or sodium bisulfate . Reducers are readily available at pool supply stores, home improvement centers and online.

Muriatic acid is powerful its used to etch concrete and you need to be careful when adding the chemical to your pool. It comes in liquid form, so you need to protect yourself from accidental spills and splashes. Always read and follow the manufacturers directions for safe handling, applying and storing of muriatic acid. A 1-gallon bottle is about $45.

Sodium bisulfate comes as dry granules and is considered easier to add and safer to handle than muriatic acid. Nevertheless, it should be handled carefully. Protect eyes and skin, and wear a dust mask to avoid inhaling any dust from the granules. A 25-pound bucket costs about $50.

The correct amount of a pH reducer depends on the water volume of your pool and its current pH level. Reducers usually come with a guide that takes into account the variables and calculates the proper amounts of pH reducer to add to your pool.

It Can Be Harmful To Humans

Its hardly a coincidence that the recommended pH level for your swimming pool water is about the same as a human tear.

This is where pool water will have the least wear on a swimmers body, and ensure the best possible water quality.

A pH level thats too high causes dry, itchy, or sticky feeling skin, and even skin rashes. It also irritates the nose and eyes, similar to the feeling of getting shampoo in your eyes .

A pH level thats too low has a similar effect in terms of skin irritation, stripping the natural oils from your body leaving you with dry, itchy skin. It also causes more severe eye irritation, such as redness, puffiness and burning of the eyes.

Note: These symptoms can also be caused by a buildup of chloramine or a high level of total dissolved solids .

Does Low Ph Affect Chlorine

Low pH has a huge impact on chlorine. Chlorine needs a pH of at least 7 to work properly, so if the pH in a pool is below this level, it will have severely reduced effectiveness.

This means that even though you may be adding enough chlorine for effective cleaning and disinfection purposes, low pH levels can increase bacteria counts dramatically which could lead to skin irritation or eye damage.

To avoid these drawbacks, keep your water at an acceptable pH range by monitoring regularly with a test kit and adjusting accordingly when necessary.

How To Raise Stabilizer In Pool Water

If you need the pH level in the pool to rise, you need to add pool conditioner or stabilizer directly to the pool. As usual, follow the directions because some manufacturers may have you dilute the powder in a bucket while others suggest that you sprinkle it directly on the pool surface. If you have a sand filter, the product may suggest that you add it to the skimmer.

Make sure that you are adding the correct amount of CYA because you can actually over stabilize your pool. Test you CYA constantly and double check your pool size before adding so you know how much CYA you need.

If you have the pool drained, still test your water before adding CYA because some places use CYA in their water treatment. Test consistently and carefully to keep your water safe and healthy.

When it comes time to add stabilizer to raise your CYA level, you need to first find out how much stabilizer you need to add. Usually, about 13 oz of stabilizer will raise the CYA level of 10,000 gallons of water by 10 ppm.

Put the stabilizer in the skimmer basket while the pump is running, and keep it running for one day after you add the stabilizer. Dont backwash or clean the filter for a week after adding the stabilizer.

You must remember that stabilizers dissolve in the pool very slowly and you wont be able to accurately test your pool or get a solid reading on the CYA for several days. Wait a week before testing again and only then add more if you need to.

Ph Down To The Rescue

Adjusting Ph and Alkalinity in your pool

If the pool pH is too high, or above 7.6, you need to lower it as soon as possible. To do this, you will need a pH reducing chemical. Our most trusted option is pH Down. It is the perfect and most efficient way to lower your pH to a desirable level again. The amount required is based on the number of gallons of water in the pool and the amount of alkalinity in the water.

You must keep your pool water chemically balanced. It is very important to remember that your pools health is also your health, your time, and your money. This is why iopool is here to help you will all your pool questions and needs.

How To Raise Ph In Pool Water

If the pH level is too low, add soda ash, also known as sodium carbonate or pH Up.

We recommend never adding more than 2 lbs or 900g of soda ash per 10,000 gallons of water per treatment.

Starting at the deep end, sprinkle the soda ash over the entire surface of the pool.

Make sure that the pump is circulating to move the water around and then wait at least an hour before testing again.

If the pH is still too low, try adding some more soda ash. Soda ash may make the pool water a little cloudy at first, but it should become clearer after a day or so.

The Important Role Of Clean & Clear Minerals With Total Alkalinity And Ph In Balancing Pool And Spa Water

Adding the prescribed dosage of CLEAN & CLEAR MINERALS to your pool or spa should have a net zero effect on pH and alkalinity.

This is extraordinarily important when it comes to the health of your pool water. C-Pool CLEAN & CLEAR is all natural minerals that can have a huge impact on the clarity and health of your water without interfering with the pH or alkalinity or balance. Pool owners have all the advantages of healthy water without having to take samples to the pool stores and paying for various chemical concoctions.

How To Increase Ph In The Pool

There are any number of commercial chemical products that you can use to raise the pH of your pool. Usually they have brand names that involve the word pH Increaser, Up, or Raise.

We recommend this pH increaser here.

Whatever their trade name, all these products are based on sodium carbonate otherwise known as soda ash. Be aware, though: sodium carbonate isnt the same thing as sodium bicarbonate, AKA baking soda.

Yes, you can use baking soda to raise the pH in pool, but its not ideal. See below.

  • Make sure that the pump and filter system is running.
  • Test your water in order to determine the current pH and, therefore, how much you need to raise the pH back to the desired 7.4-7.6 range.WORD of WARNING: pool test kits and testing strips typically only measure down to a pH of 6.8. So, if your pool waters pH is showing a reading 6.8, the actual reading may be even lower. What you need to do, first, is to bring the pH back up into the measurable range, and then fine tune from there. We recommend these Water Testing Strips and Liquid Testing Kit here.
  • Calculate how much sodium carbonate you need to add. As a general rule 175 grams of sodium carbonate will raise the pH of an average backyard pool of 32 m2, or approximately 42,000 litres of water, by 0.1.

Grams of Sodium Carbonate Required to Raise pH to 7.4-7.6

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.

How To Add The Right Chemicals To Raise Your Pools Ph Level

Thankfully, adding baking soda and soda ash is really easy.

  • Make sure your pump and filter are running so that the chemical is mixed into the pool water properly.
  • Add a small amount of the chemical right into the pool. Be sure to spread it around as much as possible and dont add too much all at once.
  • Let the chemical dissolve into the pool and circulate before adding more.
  • The act of adding any powder directly to the pool water surface is called broadcasting. Youre broadcasting the chemical around your pool.

    It takes about 20 minutes after stirring to see results. Check out how much baking soda or sodium carbonate is required based on your pools current readings!

    It Can Make Your Water Cloudy

    pH doesnt directly make your pool water cloudy. Instead, its often a side-effect of the issues weve already covered.

    The scaling caused by high pH water leads to circulation issues, which leads to cloudy water. The corrosion caused by low pH water creates debris, which also leads to cloudy water.

    And it doesnt stop there.

    Since your pH level dictates the effectiveness of your sanitizer, improper pH can lead to poor sanitation. This turns your pool into breeding ground for various types of algae, bacteria, and viruses, and can also result in cloudy or green water.

    How To Maintain A Saltwater Chlorine Generator

    SWCG maintenance is all about cell cleaning and replacement, period: Chlorine production happens in the salt cell, and a defective cell will lead to less or no production of chlorine. You need to closely monitor the cell to ensure that there is no calcium buildup, which causes a low production of chlorine.

    Ideally, even if there is no buildup, it is recommended to clean your cell at least every six to 12 months.

    I use Hayward’s AQR15 AquaRite Salt Chlorinator, which has a self-cleaning feature that makes it easy to clean any time. If you need more information, Hayward Chlorinators have a very thorough guide on how to clean salt chlorinator turbo cell.

    What Is Total Alkalinity

    Total Alkalinity is very closely related to pH, as it is a measurement of all alkaline substances in the water. Proper Alkalinity levels are a key factor in maintaining pH many describe it as being a pH buffer. Low Total Alkalinity levels causes rapid pH fluctuations, and high levels make pH difficult to adjust. That said, its best to adjust one and then the other, not both at the same time. If Total Alkalinity is out of balance, address it first.

    The best range for Total Alkalinity depends which sanitizer you use. If using calcium hypochlorite , sodium hypochlorite, or lithium hypochlorite as your primary sanitizer, the ideal TA range is 80-100 ppm. When using dichlor, trichlor, or bromine as your primary sanitizer, the ideal range is between 100-120 ppm. For a salt water chlorine generator, most manufacturers recommend TA levels between 80-120 ppm. Maintaining the right balance of pH and Total Alkalinity is essential to keeping your pool water in good condition.

    If your Total Alkalinity levels are too low but pH levels are above 6.8, you will need to add Alkalinity Increaser . When both Total Alkalinity and pH are too low , use pH Increaser to bring both levels up. If your Total Alkalinity levels are too high, add pH Reducer .

    Cyanuric Acid: What Is It And Why Do I Need It

    Cyanuric acid, or CYA, is a stabilizer that partially blocks sunlight on chlorine. If you have low pH and stabilizer, the most common product to use is Cyanuric Acid. The way it works is .

    With the correct level of CYA in the water, , you will have to add much less chlorine because the levels will be more stable.

    Be advised, however, that while stabilizers do stop chlorine from breaking down they also reduce the effectiveness of the chlorine when it comes to disinfecting your pool. You will need to keep the chlorine level higher than you normally would when there is CYA in the water in order to keep the chlorine effective.

    For example, when CYA is at 30 ppm, chlorine must be at 2 and 4 ppm, but when CYA is at 50 ppm, chlorine needs to be between 4 and 6 parts per million.

    So, if you have to keep higher chlorine levels you will have to add more sanitizer. However, this will be nothing in comparison to the amount required to replace losses caused by UV exposure if you do not use a stabilizer. Also, you will have to add chlorine much less often if you use this method.

    Can You Use Baking Soda To Clear Up A Cloudy Pool

    How to Raise Pool Alkalinity

    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.
