Does Ph Effect Chlorine Effectiveness

Chlorine is known by many as the number one chemical used for maintaining a swimming pool. It works its magic by disinfecting microorganisms.

For chlorine to do its job, it needs to be exposed to the right environment. Its ability to effectively kill bacteria depends on optimal pH and alkalinity levels.

A high pH can cause cloudy pool water while a pool with low pH means the amount of available chlorine is lower. In both instances, an incorrect pH level will hinder chlorines effectiveness.

When Is Ph Too High

4 Ways to Lower Swimming Pool pH

pH is the level of acidity in your pools water.

This acidity needs to be balanced. Too much causes problems as the water becomes alkaline, and too little causes problems as the water becomes acidic.

The pH scale measures from 0 to 14, and the ideal reading you want to keep you water at is between 7.4 and 7.6.

Some pool owners use a wider range of 7.2 to 7.8 for a bit more leeway, but a pH level of 7.5 is what you should always be aiming for.

How To Lower Alkalinity But Not Ph

Unfortunately you cant lower the total alkalinity without lowering the pH. If for example your pools alkalinity was 250 ppm, lowering it to the acceptable range of 80-120 ppm will likely result in a pH that is too low.

Theres no need to worry though. Its usually best to set a target total alkalinity level and adjust the pool for that. After youve hit your target alkalinity, or are close, then you can raise the pH by aeration.

The best advice is to take your time when adjust alkalinity and pH. Do it over several days instead of dumping large quantities of chemicals in your pool at the one time.

How Do You Describe Ph Level In A Pool

The ph level simply refers to the summation ormeasure of overall acid-alkalinity stability. In other words, it tells if apool water is alkaline or acid base.

pH measures from 1-15, but the ideal range fora pool is between 7.2 to 7.6. If a pool pH measures a 7, even better as 7stands completely neutral because it is middle of your scale.

This means that your pool becomes as acidic ashow low the number is. Also, however high the number goes, the more your poolalkalinity.

Pool water that has high alkalinity can makethe pool water appear cloudy and even scalin. Any acidic pool water can destroy your pool equipment, causing unhealthyetching on the water surface. It can worst of all, cause irritation to the eyesand skin.

    The lower on the scale your pool ph levels are, the more acidic and corrosive your water becomes. How to lower ph in pool water. Add either chemical to the pool by pouring in the pool about 6 inches above the surface to avoid splashing.

    The quickest and easiest method to correct this is to add muriatic acid, otherwise known as hydrochloric acid. The ph of the water in the swimming pools is a very important parameter to be able to swim in safety and enjoy a clean water. After you have determined the ph level, then you can start looking for ways on how to lower ph in pool.

    To lower the ph, the most common liquid acid used is muriatic acid, also known as hydrochloric acid. Muriatic acid, or hydrochloric acid, is commonly used in pools to lower the ph. Too low a ph level makes the water acid and can have adverse consequences.

    It plays an important role in the care and maintenance of swimming pools. Simply put, it determines whether your pool is acid or alkaline . How to lower ph in pool a manual or electronic pool tester will check the ph, chlorine level and total alkalinity of.

    Notes On Adding Muriatic Acid:

    • Muriatic acid is caustic. If you get it on your skin it will burn. Wear goggles, gloves, long sleeve shirt, and heavy jeans. Have a bucket of water and a hose with a sprayer attached with the water already turned on, ready to hose yourself or anything else off if you spill. If you do manage to dump it on yourself, wash it off immediately.
    • Do not spill muriatic acid on any concrete, tile, or any other masonry. I cannot stress this enough. If any of you have sealed your garage floor with epoxy based floor covering, a recommended step prior to applying the epoxy is to apply undiluted muriatic acid to the garage floor. This etches the concrete so the epoxy will stick, giving off bluish green fumes that rise off the concrete, plus some bubbling and fizzing that also occurs.
    • When working with muriatic acid over concrete, you can try to pre-wet the concrete with water to help with diluting any potential spills or drops that might end up on the concrete.
    • You typically want to dilute the muriatic acid in a bucket of water to prevent burning yourself, pool surfaces, or equipment. Some muriatic acid containers come pre-diluted so you dont have to mix with water and you can just apply directly to the pool.
    • Although it may seem crazy to put such a damaging liquid into your swimming pool water, even strong acids like this one are beneficial in small doses.

    Tips on Lowering your Swimming Pool pH

    Natural Ways To Lower Pool Ph

    There are a couple of natural household products that could potentially be used to lower your pools pH.

    Vinegar: Wondering how to lower pool pH with vinegar? Ordinary household vinegar could in theory be used to lower the pH of your pool. The pH of vinegar is about 2.5, which is quite acidic when compared to your pool water.

    Household vinegar is very weak though , so you would need quite a bit to lower pH.

    And in addition, using vinegar would cause a reaction leaving acetates in the pool water, which is not desirable. Its generally not desirable to add extras to your pools water.

    Muriatic or Hydrochloric acid is a far better choice for lowering pH and alkalinity.

    Baking Soda: Baking soda differs from the previous two natural remedies in that it has a higher pH of 8.3. If your pools pH is above 8.3, baking soda will bring it down to approximately the same value.

    However, its more beneficial to use baking soda when looking to raise pool pH and alkalinity levels. You need approximately 1.5 lbs per 10,000 gallons of water to raise the alkalinity by 10 ppm.

    What Is Alkalinity

    Briefly, alkalinity refers to dissolved salts, like carbonates, that keep pH stable. If alkalinity is in the right range, pH and chlorine levels are easier to maintain.

    To lower alkalinity, add muriatic acid. Muriatic acid lowers both pH and alkalinity.

    To raise alkalinity, add sodium bicarbonate . This is different from sodium carbonate .

    What Exactly Is Ph

    4 Ways to Lower Swimming Pool pH

    Simply put, pH stands for Power of Hydrogen. It is a measure of the concentration of hydrogen ions in a water-based solution.

    In laymans terms, pH is a scale that determines how acidic or alkaline a solution is. The pH of a solution can measure anything between 1 to 14.

    Any solution with a pH of above 7 is alkaline and a solution with a pH less than 7 is acidic.

    Pure water has a pH of 7, which is considered neutral. Hence, pure water is neither basic nor acidic.

    A higher pH is an indicator of alkalinity and a lower value, of acidity.

    Interestingly, human tears have a pH between 6.5 to 7.6, with the mean value being 7.

    If pool water is too acidic, it can cause eye and skin irritation. Acidity also causes etching on the pool and leads to corrosion of pool equipment.

    On the other hand, if the alkalinity of pool water is on the higher side, it causes scaling and gives the water a murky, cloudy look. While this might not seem like too much of a problem, it is essential to note that a high pH can undermine the effects of chlorine. In such a case, the pool becomes unsuitable, even dangerous, for swimmers.

    What factors affect the pH of pool water?

    Anything that is added to the pool alters the waters chemistry and directly affects the pools pH. Cleaning agents, detergents, perfumes, swimmers waste, source water, rate of evaporation, dirt, debris etc cause a change in the pH. This is why it can be a bit tricky to find the right chemical balance in a swimming pool.

    How Much Acid Should I Add To My Pool

    This depends on how high your pool’s pH is and the size of the pool. If you are using test strips, it’s usually hard to determine exactly how high the pH level is you just know it’s high. A better test kit, or a DPD drop test kit, will use phenol red to give you a better idea of your true pH reading. Some better test kits include an “acid demand” test to help calculate a more precise dosage.

    If you have a pH reading of 7.8 or higher, and an average size in-ground pool, you should add 1/4 gallon of muriatic acid, and re-test after the water has circulated for an hour. If you have a smaller pool, or an above-ground pool, you would start with one cup of acid, and then re-test and add more if needed. If you have a spa, we are talking only capfuls at a time. Very little acid is needed to adjust pH in a spa.

    For a more exact idea of how much acid to add, see the table below or use a pool calculator, which can be found online, that will give you an amount based on estimated pool volume and chemistry.
