How Long Does It Take To Raise Ph In Pool Water

How To Fix A High Swimming Pool pH Level Problem

It may take several days to raise the pH level in pool water to the correct the pH level. I recommend to use a smaller portion of pH increaser chemical at first and test again the next day. You can always add more chemical again the next day. If you add too much you create another problem where the pH is too high.

Use Flocculant To Clear Up The Algae

Youve disarmed the enemy , but its presence still lingers.

The best way to clear out the rest of the pool algae is to use a pool flocculant.

Flocculants are normally used to clear up cloudy white swimming pools. They work by clumping particles together and sinking them to the bottom of your pool making it easier for you to clean up and filter out.

Use 1 2 treatments of pool flocculant depending on the severity of the pool algae. After adding it to your pool, give the flocculant some time to settle in.

Once you see the algae sinking to the bottom, its time to finish the job.

What Causes A High Ph In A Swimming Pool

It happens all the time. Swimming pool pH climbs, or sometimes spikes, and all sorts of problems like calcium dust and carbonate scale can occur. But what causes high pH in pools? Why does the pH sometimes climb, and other times stay relatively steady? In this article, we will discuss pH and how it shifts, and offer some remedies to correct the pH, based on each situation.

The most widely used substance to raise the pH level in pool water is sodium carbonate which is commonly called soda ash. There are many branded products with names such as pH Increaser, pH Raiser, etc. which all contain basically the same ingredients in varying concentrations. Any of these will do the job.

Just make sure you follow the instructions on the container and dont add too much on the first application. If you add too much chemical you will increase the pH too high and need to purchase another chemical to reduce the pH. Add the chemical to the water above the outlet jets to ensure its well mixed into the water and leave the pump running for at least an hour.

A common problem for pool owners, especially if they have just bought the house, is they dont know the volume of their pool. To determine the correct amount of chemical to add to the pool you will need to know the volume of the pool in gallons or liters. This is simple to calculate if your pool is round or rectangular. However, if your pool is kidney, peanut, trapezoid, or some other custom shape and the pool varies in depth you will need to find out from the pool builder.

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!

    How To Raise Ph Levels In Your Pool

    Maybe you have noticed something off with your pool water, or perhaps it was just time to test the water. You run the test, and the pH is low. You retake it to be sure and again, it is low. What steps can you take to raise the pH level and get it back in balance?

  • Check your Reagents
  • Check Alkalinity and Add Baking Soda
  • Aerate the Water
  • There are a number of things that you can try to correct the issue and raise the pH level in the pool. Before you go to the trouble of adding products and additional testing, double-check your reagents. Your test strips should be replaced at least once per year, if there is a chance that these are out of date, buy a new test kit and test again.

    You Recently Shocked Your Pool

    Shocking your swimming pool refers to the process of adding chemicals usually chlorine to stabilize the pH level.

    Shocking breaks up combined chlorine killing algae, bacteria, and other pathogens and it rapidly increases your chlorine level.

    Combined chlorine is essentially chlorine thats bound to ammonia and nitrogen. Translation: its an ineffective sanitizer when in this state.

    Adding shock breaks up the combined chlorine and creates an increase in free chlorine. This increase can spike your pools pH level.

    Pool shock is available in both chlorinated or non-chlorinated versions. If your pool already has a high pH level, using chlorinated shock will only make things worse.

    Can I Use Baking Soda To Raise The Ph

    Yes you can. But there are a couple of drawbacks.

    • Baking soda is only about half as efficient at raising pH.
    • Baking soda not only raises the pH, it also raises the total alkalinity. What that means in practice is that you should only use baking soda to raise pH when the total alkalinity is significantly below its desired range of 80-120 ppm. If the total alkalinity is close to or within the 80-120 ppm range, the danger is that baking soda will over-raise the total alkalinity: and then you will suddenly be two chemical levels out of whack instead of just one.

    Why Your Pool Ph Balance Is Important

    Swimming pool water is treated with chemicals to disinfect and oxidize. An optimal pH balance is essential to maintain sanitary swimming conditions and the longevity of pool equipment. Although some other chemicals have been introduced into the market, the most common chemical used to treat swimming pools is chlorine.

    Chlorine works in two ways:

    • It disinfects the water by killing bacteria and algae that cause waterborne illnesses. Bacteria in pool water can cause swimmers to suffer from diarrhea, swimmers, ear infections, and skin infections.
    • Chlorine also oxidizes dirt and debris particles that come into the water from swimmers and the environment.

    Maintaining an optimal pH is important because it can impact the effectiveness of the chlorine and ultimately lead to unsanitary swimming conditions. In addition to health, it is also essential for the comfort of swimmers the optimal pH for swimming pools is the same pH as the human eye and mucous membranes. Unbalanced pH can lead to itchy and irritated skin and eyes for swimmers.

    And if the health, safety, and comfort of swimmers are not enough, pH balance is essential for the longevity of the pool facilities and equipment. Overly acidic pool water is corrosive and will lead to the breakdown of equipment like pumps, ladders, and diving board structures. Unbalanced pH levels also wear down the pool liner and will create the need for more frequent replacements.

    Why Should You Lower Your Pool’s Ph Balance

    DIY Pool Water Testing

    If your pool has a pH balance that constantly gets a little too high, you could start to notice some pretty significant problems.

    It can even be dangerous for swimmers, killing the chlorine benefits and posing some serious health concerns.

    Here are some things you might see:

    • Skin and eye irritation
    • High chlorine demand
    • Cloudy water

    Clogged filters and scaling may not sound like a big deal, but when you consider that it can affect circulation and put a strain on your pool equipment, you might start seeing dollar signs.

    Imagine, for example, that you get some severe scaling in a pipe, which causes your water not to be able to move through it at the same speed.

    In this case, your pump is still pushing water through your pipes just as fast as it was before, but now your system cant quite handle it.

    This can cause pipes to burst or your motor to burn out, both of which can result in some pretty expensive repair bills.

    If your pH dips below normal range in your pool, your plumbing may start to erode and your swimmers will start to complain with itchy skin and burning eyes. Talk about ruining summer fun!

    To raise the pH levels in your pool, try adding sodium carbonate or sodium bicarbonate until your pools pH levels are between 7.2 and 7.8.

    If your pH levels are a little low, keep on reading: in this ultimate guide, well go over what pH is, why pH balance is important, what causes low pH, and how to raise pH levels in your pool.

    Getting The Right Ph Level

    You may not get the right pH level for your pool water in one go, so be prepared for a bit of trial and error. When adding additives, always start on the low end. Check

    out below what to add to the water when the pH reading is either too high or too low.

  • Low pH level: If the pool water is acidic, raise it by adding sodium bicarbonate. The levels vary depending on the pH level. It is recommended to add around nine pounds of sodium bicarbonate for every 10,000 gallons of water.
  • High pH level: If the level becomes too high, heres how to lower the pH in a pool: throw in a dry acid such as sodium bisulfate. Match the amount of dry acid you add based on the pH reading. For instance, if you have a 50,000-gallon swimming pool and the pH reading is 8.0, you should throw in 900 grams of sodium bisulfate.
  • After adding the appropriate substance, monitor the water pH level. If it has not stabilized after two days, continue to add the substance to lower or raise the pH.

    Guide To Raise The Ph Level In Your Pool Safely

    If you have a swimming pool at home, youll need a pool testing kit to ensure that the water levels are all properly balanced.

    If the water in your pool is too acidic, this will corrode your equipment, and its likely to bring about etching on surface materials. Beyond this, acidic water will irritate your eyes, nose, and skin.

    If, on the other hand, your pool water is too alkaline, this can cause scale to develop on the surface as well as all over your pool plumbing gear.

    Neither of these scenarios is ideal. Excessive acidity or alkalinity both impact the efficiency of the chlorine in your pool, and resultantly impede the process of disinfection.

    When youre checking the pH level in your pool, you should aim for somewhere between 7.2 and 7.8. On the pH scale, 0 is extreme acidity, with 14 representing extreme alkalinity. 7 is neutral, so youre shooting for just the alkaline side of neutral.

    Now, before we show you how to raise the pH level in your pool, a few more basics so you can proceed better informed

    Measure And Adjust Calcium Hardness

    If you ever notice a while line or scaling around your pools water line, its probably calcium buildup. And how often you see it is directly related to your pools calcium hardness level.

    Ideal Calcium Hardness level: 200 400 ppm

    How to increase calcium hardness:

    To increase your pool waters calcium hardness use calcium chloride. Follow the usage instructions printed on the packaging.

    How to decrease calcium hardness

    • Partially drain your pool and refill it with fresh water.
    • Use a flocculant to collect and vacuum excess calcium.

    Sanitizer is what keeps your pool free of germs and bacteria. Without it, every pool would quickly become a breeding ground for germs.

    But luckily, we use sanitizers like chlorine to keep the water safe and healthy.

    When it comes to measuring chlorine, there are a few numbers to keep track of:

    • Free Chlorine
    • Measures the amount of unused, or available chlorine in the water
  • Total Chlorine
  • Measures the total amount of chlorine present in the water
  • To find your pools combined chlorine : subtract Total Chlorine from Free Chlorine

    Ideal levels for chlorine: 3 ppm

    Chlorine comes in a few forms:

    • Chlorine tablets
    • Salt chlorine generator

    For this step, you can save time and shock your pool now. This gives you a jump start on refreshing the water and takes care of sanitizing your pool.

    A few other pool sanitizers:


    Healthy pool bromine levels range from 3 ppm to 5 ppm


    Proper levels for biguanide: 30 to 50 ppm

    Cause #: Circulation & Filtration Issues

    How to Lower pH in Pool

    Pool water that isnt being properly circulated is always at risk of becoming cloudy water.

    Thats because circulation pushes your pool water through your filter system, so without it, the filter cant work its magic and keep your water squeaky clean.

    There are a few moving parts to this, so lets go through them.

    Is Your Pump Powerful Enough?

    A pool pump is a core part of your filtration system as it cycles your water through the filter in order to remove debris and maintain circulation, this prevents the water from stagnating which eventually breeds other problems.

    With that in mind, you need to make sure your pump has the ability to cycle the entire contents of your pool at least once per day. Whats more, youll need a pump that can complete a turnover in an 8 hour period.

    The speed at which a pump completes a turnover is based on two factors:

  • The volume of water in your pool
  • The flow-rate of the pump itself
  • Note: Flow-rate tells you how many gallons of water pass through the pump each minute, and its appropriately measured in gallons per minute .

    To properly size your pump, divide your water volume by 8, then divide again by 60. What youre left with is your pools required turnover rate in GPM. The flow-rate of your pool pump should be at least the same.

    Is Your Pump Suited To Your Filter?

    You wouldnt put all that effort into correctly sizing your pool pump only to neglect your pool filter, would you?
