Shock will typically lower alkalinity in water. Alkalinity is a measure of the ability of a water to neutralize acids. It is generally composed of bicarbonate and carbonate ions, with some contribution from other minerals such as hydroxides and phosphates.
When shock is added to water, it reacts with these components to produce other compounds, and consequently, reduces the alkalinity. The amount of alkalinity decreased through shock treatment will depend on the amount and type of shock used.
For example, the use of calcium hypochlorite (cal-hypo) will reduce the alkalinity more than potassium monopersulfate (mp-shock). Of course, pH changes as well, and without regular monitoring of pH, alkalinity, and other important water parameters, shock treatments can easily go awry and result in poor water quality.

Should I shock pool if alkalinity is high?
The answer to this question depends on the alkalinity levels and other related factors. Generally, it is not recommended to shock your pool if the alkalinity is high. High alkalinity can contribute to cloudy water, but it is rarely the sole cause.
It is important to test all the chemical levels in your pool before determining the best course of action. If the alkalinity is much higher than the ideal range of 80-120 parts per million (ppm), it is best to first address the factors that are causing it.
That may include correcting pH and calcium levels, or testing the water for metals such as copper or metals that bind to alkalinity, such as manganese. If after correcting other factors and the alkalinity is still high, then shocking the pool may be necessary.
Be sure to use the correct type of shock, follow manufacturer instructions and wear the appropriate safety equipment.
What to do if alkalinity is high in pool?
If the alkalinity in your pool is high, the first thing you should do is to check the chlorine levels. If the chlorine is too low, the alkalinity will rise because the chlorine is required to keep the total alkalinity in balance.
Once the chlorine has been adjusted to its recommended levels, you can then adjust the alkalinity by adding an acid, usually muriatic or dry acid. However, before adding any type of acid, it is essential to make sure your pH is within the optimal range of 7.
2 – 7. 6. Lower or higher pH levels will make the alkalinity adjustment difficult or even ineffective. The ideal way to reduce alkalinity is to use a product specifically designed to lower alkalinity.
Follow the product instructions carefully and make sure to add it slowly to the pool, in small amounts at a time, so that it does not cause any shock to the pool. Additionally, it is recommended to test the alkalinity regularly, at least once per week, until the levels are back within the ideal range.
Do I add shock or alkalinity first?
When adjusting your pool’s chemicals, you should add alkalinity first and shock afterwards. Alkalinity helps to maintain the pH balance of the water, so if it is out of range, you will want to adjust the water to get the alkalinity back in proper range before anything else.
Then, once you have the alkalinity in balance, you can add shock to your pool to keep chlorine levels healthy. By shocking the pool, you are helping to eliminate bacteria and contaminants in the water, ensuring clean and safe swimming conditions for everyone.
It is important to note that you should always follow the manufacturer’s instructions for adding chemicals to your pool.
How do I lower the alkalinity in my pool but not pH?
Lowering the alkalinity in your pool but not pH can be done by adding a pool buffer or a specialized alkalinity reducing product. A pool buffer is designed to bring down total alkalinity and not impact pH, while a specialized product works by counter-balancing high alkalinity.
It is important to keep the pH between 7. 2 and 7. 8, so pH adjusting products should not be used to lower the alkalinity. When adding the producst, make sure to follow the instructions on the package to ensure proper dosage.
When adjusting alkalinity, be sure to test the pool water and measure alkalinity levels after each addition, continuing to add product in small increments until you reach the desired alkalinity level.
After adjustments, continue to make regular tests to ensure that the alkalinity does not drop.
What order should I correct my pool chemicals in?
The order for correcting pool chemicals will depend on the specific chemical levels that need to be adjusted. Generally, you will want to adjust the chlorine levels first. Test the chlorine level and then adjust it, if necessary, to between 1 and 3 parts per million (ppm).
After you are done with the chlorine testing, you should then test and adjust the pH level. Aim for a pH level between 7. 2 and 7. 8. You also should test and adjust the alkalinity level to be between 80 and 120 ppm.
Lastly, you should check and adjust the calcium hardness level to be between 150 and 250 ppm. Regardless of what chemical levels need to be adjusted, it is always important to follow the manufacturer’s instructions for your pool chemicals and to use appropriate protective gear when working with the chemicals.
What is the correct order for pool chemistry?
The correct order for pool chemistry is Test, Balance, Clean, and Shock. Test the pool water first with a test strip and measure the levels of pH, alkalinity, calcium hardness, and chlorine. Once you have the water chemistry levels, balance the levels to the optimal range for healthier and clearer water.
After the water is balanced, you should clean the pool of debris, oils and any dirt that is on the surface or on the walls of the pool. The final step is shocking the water, which refers to shocking the pool up with a large dose of chlorine to remove any remaining bacteria, algae and other contaminants.
This process should be repeated weekly for optimum pool health.
How long after adding alkalinity increaser can I add chlorine?
You should wait at least 24 hours after adding alkalinity increaser before adding chlorine to your pool. This is to give the alkalinity increaser time to fully dissolve so that chlorine can be added to the pool safely.
For best results, make sure to test your pool’s alkalinity before adding chlorine to make sure it is at the proper level. Once alkalinity has reached the corresponding range according to your pool’s chlorine recommendation, it is safe to add chlorine to your pool.
Does it matter what order you put pool chemicals in?
Yes, it matters what order you put pool chemicals in. Pool chemicals are powerful and can damage your pool and its equipment if not added in the right order. Generally, the rule of thumb is to start with the least acidic chemical first, then move on to those with a higher pH level.
Always add liquid chemicals in the skimmer before powder and granular chemicals, which should be added directly to the water. Additionally, some chemicals, such as algaecides, should never be added directly to the water but instead should be pre-diluted first.
Finally, it’s always best to add the chemicals while the filter pump is on, which will help the chemicals to become more evenly distributed.
Should I adjust alkalinity or chlorine first?
It is important to decide when to adjust alkalinity and when to adjust chlorine levels in a swimming pool since the two are closely related. Chlorine is essential for keeping a swimming pool free of bacteria and safe from contamination, while alkalinity helps prevent the pool water from becoming acidic.
Generally speaking, adjusting alkalinity should come before adjusting chlorine levels, as chlorine can help reduce the alkalinity of water. High levels of chlorine can cause a pool’s pH to drop, and as alkalinity helps to stabilize pH levels, it is best to adjust alkalinity first before adding chlorine.
This ensures that it is easier to maintain a balanced pH level without having to constantly adjust levels of both alkalinity and chlorine. Additionally, testing the pool water both before and after any chlorine or pH adjustments is important to ensure proper balance and water quality.
What decreases alkalinity in a pool?
A decrease in alkalinity in a pool can be caused by a variety of factors. In most cases, it is simply a sign that the pool needs to be balanced. Common external elements, like rainwater, can also be a factor in decreasing alkalinity in a pool.
Rainwater can be high in acidic elements, like carbonic acid, which can slowly decrease the alkalinity of a pool over time. Swimmer waste, such as sweat, urine, and body oils can also contribute to a decrease in pool alkalinity.
When chlorine is used to sanitize a pool, it can also decrease the alkalinity—though the degree of the decrease depends on the total alkalinity of the pool and the type of chlorine being used. Running the pool’s filtration system can help to correct the balance of alkalinity, but if all else fails, a professional can help to diagnose and fix the issues with alkalinity.
Does alkalinity up clear pool water?
No, alkalinity does not necessarily clear pool water. The clarity of pool water is actually determined by the presence of contaminants, such as organic matter, and chemical balance. Alkalinity is a measure of the water’s ability to resist changes in pH, not clarity.
To clear pool water, it’s important to first test for proper chemical balance to ensure that pH, free chlorine and total alkalinity levels are balanced. Regular pool maintenance, such as brushing the walls, vacuuming and skimming the water surface, and maintaining circulation is also beneficial in helping to keep the pool clean and clear.
Additionally, certain pool products, such as clarifiers and flocculants, help to bind small particles together, making them easier to filter out.
What causes pool alkalinity to be high?
Pool alkalinity can become high for a variety of reasons. One of the most common reasons is that the alkalinity level of the tap water used to fill the pool is already high. Hard water generally has a higher alkalinity than soft water.
Additionally, excessive use of baking soda to raise the alkalinity of the pool could cause it to be too high. Lastly, water temperature can also be a factor, as warmer water can cause the alkalinity to increase.
A high alkalinity level can decrease the efficiency of chlorine, thus leading to more frequent pool maintenance and increased costs for pool chemicals. It is important to keep the alkalinity level in balance, as it affects many other factors in a pool’s chemistry.
Most experts recommend an alkalinity level of 80-120 ppm for optimal performance.
How do you reduce alkalinity in water?
Alkalinity in water can be reduced by using a combination of treatments. First, reverse osmosis is a very effective way of eliminating alkalinity from water, although it can be cost prohibitive in some cases.
Second, by using an acid like sulfuric acid, muriatic acid, or nitric acid to lower pH, alkalinity in the water can be reduced. Third, different types of water softeners can also be used to reduce alkalinity.
Fourth, ion exchange technology can be used to remove bicarbonate ions in water, which is responsible for increasing alkalinity. Lastly, blending treated water with untreated water can also be a useful option depending on the circumstances.
