From there, you can test the alkalinity once again after 6 hours. One example of that is when you want to lower the water’s alkalinity but you do not want the pH level to go lower. So the process of waiting out the alkalinity may be the most natural way to do it but it is not the most viable option for most people.
The process takes time and there is a high chance that you might lower the pH level below the recommended level. However, muriatic acid is the best chemical to use in order to lower the alkalinity levels. Consult the directions on the bottle to determine how much dry acid should be added, bringing the total alkalinity to between 80 and 120 ppm. When the pH goes up, it enters into alkaline territory on the pH scale. This rise will gradually increase the total alkalinity level as well. Muriatic Acid if broadcast and splashed across the pool surface will lower pH greater than it will lower alkalinity.
Why you need to lower alkalinity
Oils enter pool water from swimmers – the oil on their skin, as well as from sunscreen. Pool chemicals like chlorine and oxidizers are normally what help to remove these oils from your water, keeping it clean for swimming. Simply lower both the pH level and total alkalinity using muriatic acid, then aerate the water by disrupting the surface for a prolonged period of time.
It’s not uncommon to see your total alkalinity rise over time because pH naturally rises over time, and we know alkalinity always increases with pH. For most pools, the ideal range for total alkalinity is anywhere between 80 and 120 parts per million. This is the sweet spot for most pools where alkalinity keeps the pH level stable enough to keep everything in balance. It’s better to go ahead and stay on top of keeping your pool’s levels balanced than to risk unsafe or unclean water. Once you’ve gotten out your vial and reagent for testing, collect a sample of pool water about 12” below the surface. Then drop the reagents slowly into the water sample and use the manufacturer’s directions to determine your reading.
Do You Really Need to Lower Alkalinity?
One reason could be that the pH level in the pool is low, and the alkalinity is being used to try to balance it out. Another possibility is that there is something in the pool water that is raising the alkalinity levels, such as high levels of calcium or magnesium. Yes, it is safe to swim in a pool with high alkalinity. High alkalinity helps to maintain the pH balance in the pool water, preventing it from becoming too acidic. This ensures that the water is safe for swimming and does not cause skin irritation or other problems.
You should see that your pH level is now very low (don’t panic, this is normal) and your alkalinity is about where it needs to be. Remember, lowering alkalinity can only be done through lowering pH. The problem with trying to adjust one of these values is that pH and alkalinity are very closely related.
How to Lower Total Alkalinity and Adjust pH in a Swimming Pool
It could be the addition of rain water, which is naturally acidic, or it could be from swimmers entering the pool, as our bodies are slightly acidic. Baking soda is another option for lowering the alkalinity of your pool. Sodium bicarbonate comes in powder form and can be sprinkled directly into the water. However, the amount of baking soda you add should be proportionate to the amount of water in your pool. You should measure the pH of your water before and after adding muriatic acid to ensure that you add the right amount of muriatic acid.
If you find that the pH level of the pool is lower than 7 ppm, you need to give more aerators as an addition to the pool’s pump. The unstable alkalinity level also affects the pH level of the pool. Typically, you will need to add the pool water to the tube then add the reagents, then follow the manufacturer’s instruction to check the alkalinity level. Having a swimming pool is not only about the fun, but you also have to pay attention to the regular maintenance that it needs. Most of the regular maintenance of a swimming pool is all about keeping the chemical of the water in an ideal level, so you can swim around comfortably.
It will determine the amount of muriatic acid which will be the main material for the lowering process. Test the pool water.Retest the total alkalinity level after six hours, but before 24 hours after you have added the dry acid mixture. You need to add more muriatic acid to farther lower both TA and pH, then give your pool time to aerate in order to raise the pH level. Please take readings for both TA and pH after 24 hours and not immediately as this process may need more time to get perfect balance of TA and pH.
This may seem obvious, but please make sure to use the unscented brand of bleach. If you add a half gallon of bleach to the water you can raise the chlorine level in a 10,000-gallon pool by 5 ppm. Another method to lower the pH in your pool water naturally is to just leave it alone. Minerals that decrease the pH build up naturally over time. If you let this happen the pH is going to go down on its own. Continue to use the test strips to check the levels and you should change the water once it gets below the recommended pH.
Other alkalinity-lowering products include sodium bicarbonate and muriatic acid. These are safer to use, but require storage in a dry place and must be kept away from moisture. They work by lowering both the pH and alkalinity of the water, but you should always retest both after adding the acid. Hopefully at this point, your pool’s alkalinity levels are back within normal range, but you might still have a few common questions regarding the process.
Getting a perfect balance of pH and alkalinity is a little tricky since acid will lower both but not at the same rate. If you have high pH and TA in your pool, here is the easiest way to lower and balance pH and TA in your pool without using any extra equipment like an aerator. If not, today you can find a lot of websites that offer the manual pool calculator, you can use them for this step.
Get pH to at least 7.0 first before adjusting total alkalinity. Swimmers will often experience irritation while swimming in a pool with high alkalinity. Skin and hair will feel sticky, and their eyes might burn. Next, you should determine how much of this acid you need. Manufacturers provide clear direction on how much to use. Combining this information with your alkalinity measurements should help you figure out how much to use.
People have been using household products in their pools for years and they definitely work. However, they are meant for tradition chlorine-based pool systems only. Although the next technique is a laborious one, it is definitely doable. You can lower the pH in your pool naturally by directing the downspouts from your house into the pool. If a pool becomes too full due to backwash it dumps water. Since rain is about 5.6 pH it is going to bring down the pH of the water naturally.
How to Lower Alkalinity in Pool: Everything You Need to Know
However, it is still essential to test it at least once a week. Pool water requires proper balance to remain safe for the swimmers. Therefore, when the alkalinity level is too high, there will be problems. Common issues that result from high alkalinity include irritation to skin irritations, burning eyes and premature degradation of swimsuits.
Burning eyes and itchy skin are signs of high alkalinity, and it will also prematurely degrade bathing suit fabrics and goggles. Total alkalinity keeps your pool water’s pH level in check by absorbing fluctuations in the water balance. Turn the swimming pool pump off.Wait one hour for the water to stop circulating in the pool, as you want the water to be as still as possible. Also, remember to test the levels several times at least a few hours apart to ensure you get accurate results.
