How To Lower Total Alkalinity
Although not as common as low total alkalinity, high TA can affect your pool water. For instance, you can get skin and eyes irritations when swimming in a pool that has high TA. Adding a pH reducer will stabilize the pH levels in your pool while lowering the total alkalinity.
Turn off the pump and sprinkle the pH reducer into one spot in the deep end of your pool. Let the chemicals react for around 30 minutes before turning the pump on again. Test the water again to ensure that TA has reached an optimum level.

Simple Science Goes A Long Way
Maintaining the proper balance of chemicals in your pool is a continuous process. Any new material that enters your pool , will influence the waters chemistry. In addition to pH, it is important to monitor total alkalinity, calcium hardness and total dissolved solids. Pool health is also your health, your time and your money. With the proper professional products and weekly testing, maintaining balanced water chemistry will become an efficient, simple process.
Why Raise The Pool Water Alkalinity Level
This Page at a Glance
One of the biggest reasons to keep your alkalinity level balanced is low pool water alkalinity can be damaging to your pool. Pool walls and surfaces can be etched, pitted, cracked, and delaminated. Metals surfaces can discolor, corrode, then finally dissolve. This can result in stained pool walls. With low alkalinity, the water pH is no longer stable, and minor changes in the pool chemistry can cause large fluctuations in pH, often called pH bounce.
Not only will you have trouble with damaged pool surfaces and equipment, but any chlorine added to the pool is less effective. The result is you have to add much more chlorine to achieve the same sanitizing effect. This adds expense and takes more time to keep the chlorine level at the desired concentration.
Swimmers will also complain, as water that is low in alkalinity will also often bring the pH level down in the water. The resulting water is acidic, which can sting eyes, nasal passages, and skin.
I discuss all the individual ways low pool alkalinity can cause trouble in the article: Maintaining Swimming Pool Alkalinity.

How To Lower Alkalinity With Muriatic Acid
There are a few chemicals you can use to lower your pools alkalinity level, but muriatic acid is the most common.
In order to lower the alkalinity levels, just follow these easy steps:
- 1Turn off your pools pump and wait about an hour for the water to stop moving completely.
- 2Read the directions on the bottle to determine how much acid needs to be added to your pool in order to lower it to under 120 ppm.
- 3Follow the manufacturers directions on how to add it to your pool. Muriatic acid is always somewhat diluted, but certain brands require further dilution before adding it to the water.
- 4Pour the product into the deepest part of your pool and allow to sit in still water for about an hour.
- Test the pH levels.
The problem with unbalanced alkalinity levels is mainly how it affects the pH levels.
If your pools pH levels are still low , you may have to use an aeration process along with adding muriatic acid.
I only recommend this process in extreme situations where you are unable to lower the pH levels naturally after using the muriatic acid process more than once.
Usually, leaving the pools pump running on high is enough of an aeration process, but if an extra process is necessary, you can use a compressor at the surface of the water or use a special aerator to insert into the pool.
If you attempt this process, do it slowly and carefully as you can also risk over-aerating.
Lowering your pools alkalinity levels is sometimes a slow process.
How To Use Muriatic Acid To Lower Your Pools Alkalinity
You dont have to shell out a fortune for fancy additives to manage your pools unruly alkalinity level. Good ol muriatic acid readily does the trick. Dont just pour some acid into your pool, though, or youll be doing way more harm than good.
Left untreated, high alkalinity can cause damaging scale to form inside your pool and circulation system. It can drag pH up with it, and throw your water chemistry all out of whack. Adding muriatic acid is an easy, inexpensive way to lower your pools alkalinity. All you need is a bucket, some safety precautions, and a little patience.

Calcium Hypochlorite Chlorine Shock
The most common cause of high pH in a swimming pool or spa is the type of sanitizer or chlorine shock we use in the pool.
Calcium hypochlorite or granular chlorine is non-stabilized chlorine that comes with high pH levels, and if pH level is not monitored properly, you will have high pH issues in your pool and spa.
At The Summer Pools, we always recommend using liquid chlorine, also known as sodium hypochlorite.
Sodium hypochlorite is pH neutral since it produces hydrochloric acid and sodium hydroxide as bi-products, and hydrochloric acid will naturalize the pH that is produced by sodium hydroxide.
If you have a saltwater pool, a saltwater chlorine generator will produce chlorine using sodium through a process called electrolysis, where the only bi-product is sodium hydroxide that has high pH levels above 13.
This explains why pH levels tend to get high in saltwater swimming pools and can only be offset by adding strong acids like muriatic or hydrochloric acid and sulfuric acid.
Summary Of Key Points
- Total alkalinity should only be lowered when it causes a significant rise in pH levels, or when it causes calcium scaling through CSI.
- To lower pH and total alkalinity, use a strong acid such as muriatic acid, sulfuric acid, or sodium bisulfate, all of which lower both pH and TA, but at different rates.
- You need to use an accurate water test kit that can give you correct readings. If possible, find software that can help you get exact amounts of dry acid to add into the water.
- This process may take longer than anticipated, depending on how high pH or total alkalinity is and how low you need to bring them down before the aeration process begins. However, you can always use an air compressor or any other aerator to accelerate the process.
- If you have achieved the ideal reading for total alkalinity but the pH is scaling up because the process of aeration has not yet ceased, you can use borate to keep the pH stable. The recommended level for pH is around 7.4 or 7.6.

Pool Ph Will Not Increase
If it seems like you keep adding pH Increaser or Decreaser, but it only seems to last a day, or maybe seems to have no effect at all high Total Alkalinity levels over 120 ppm may be preventing you from making an effective adjustment. For pools with high alkalinity and high pH levels, add pH Decreaser or other acid, to affect both.
Causes Of Falling Alkalinity
Alkalinity levels can decrease for a wide range of reasons, which extend to:
- A high amount of rainwater entering the pool, which leads to the water being diluted
- Acid rain can cause alkalinity levels and pH levels to drop
- Sweat and even urine may cause alkalinity levels to lower
- If you happen to shock your pool with chlorine tablets, its important to understand that these tablets have low pH levels, which means that using too many chlorine tablets can lower alkalinity levels

How To Boost Alkalinity In Pool
If a significant drop is in the pool waters alkalinity, it has to be raised to maintain a balance. So, take a look at the step-by-step procedure for doing this:
- Get complete protection for your eyes and your hands while adding sodium bicarbonate into the pool.
- Make sure to switch off the pump. Once done, spread the chemical well deep inside the pool.
- Try adding the chemical gradually. Once done, try sinking a handful of it into the pool.
- Give a few hours to allow the chemical to get completely dissolved in water. Once done, switch on the water pump.
Storm and debris have a significant effect on your pool chemistry. So after a storm, assess your pool chemical balance by following the step by step process and re-adjusting it. It is a good practice to clean the pool regularly to eliminate debris and leaves. You may clean it manually or using an automatic pool vacuum cleaner.
Its All Coming Up Alkaline
Thats a job well done. Now that you know how to use this common chemical to increase alkalinity, keeping your pH and total alkalinity at the perfect levels will be a breezewhich, by the way, hopefully didnt blow baking soda into your eye.
Not only do you have a heavier wallet, but your waters are going to give an even more comfortable swim. Ahhh…
Congratulations, and see you at the pool.

Summary Of Balancing Ph And Ta
– In any case, you get your TA levels lower than recommended levels that are between 80 and 120ppm but pH level is OK, use alkalinity increaser to raise TA back.
– If you have low pH but the TA level is OK, use borax to raise your pH without raising your TA levels.
– Use muriatic acid to lower both pH and TA when high. Use borax to help you raise pH when TA level is still high and you need to add muriatic acid so that you don’t get your pH lower than 7.0.
– Finally, it’s not possible to have low pH and high TA in the same water, or high pH and low TA in the same water. If you have one of the two situations, something must be wrong with your test kit and you need a better one.
Why Does Pool Alkalinity Matter
Some people reading this may be wondering, why should I care about changing the total alkalinity levels in my swimming pool? It would just mean pouring another chemical into the water.
This is true your pool alkalinity will require specialized chemicals to change. As of yet, theres no perfect combination of chemicals to suit every pool youll have to test the water and address the unique balance of your pool water. And regulating the alkalinity in your pool is essential for several key reasons.
First of all, it is important to know what alkalinity is in the first place. Alkalinity is a chemical that is used to neutralize acidic properties in the water. Maintaining the alkalinity in a swimming pool is key to maintaining a healthy chemical balance.
The pH typically measures this in the swimming pool, which can be determined through the use of a pH meter placed into the water. The pH of swimming pool water tends to range between one and 14 pH. A lower pH means that the water is more acidic, while a higher pH means the water is more alkaline.
Issues can also arise if your pool has too low of a pH and is too acidic. High acidity in a swimming pools water can cause irritation to the eyes and skin, particularly the burning red eyes common in public pools in which more chlorine is used for sanitation reasons. Competitive swimmers will also be actually aware of the sensation of walking into a pool room and being hit with a wave of evaporated chlorine.

Why You Should Nail Pool Alkalinity
Slightly alkaline water thrives the most in poolsthats why the ideal pH level for pools is in the range of 7.4 to 7.6. Remember, anything above 7 is alkaline.
Water in this range is easier on your pool equipment and increases your systems longevity. That means your pool pump, pool filter, plumbing, and more are slated for continuous, healthy use. Thats always great for a pool owner to hear, especially those who just upgraded to a variable-speed pump due to updated federal law in 2021.
Perhaps even more importantly, this level keeps water comfortable for swimmers. Ever left the pool with stinging red eyes? You mightve been taught to blame an excessive amount of chlorine, but the culprit is often water that is just too acidic. Keep in mind, human eyes and mucus membranes have a pH of 7.4.
Again, pH and alkalinity are not the same. So why did I just outline why a slightly-alkaline pH level matters so much? Because without total alkalinity, it wouldnt be possible.
