Sodium carbonate is something chemists recognize as soda ash, and it’s one of the most important chemicals used in manufacturing facilities today.
Glass manufacturers, soap makers, paper producers, and other similar companies use soda ash on a regular basis to create their products.
Although pool owners also use it on occasion to raise the pH balances of swimming pools, it isn’t as popular as baking soda because it has a larger effect on the total alkalinity of water (making the pH too high for swimming).
The best solution when trying to increase the pH level without affecting overall alkalinity is to use sodium carbonate instead.
What is soda ash for pools
Soda ash is a chemical compound used to raise pH and alkalinity in swimming pools.
This carbonic acid then turns into bicarbonate ions, an important part of buffering capacity that is essential for an effective balance in pool chemistry.
When mixed with water this compound forms carbonic acid which acts as a pH buffer that helps reduce chlorine loss by the way of chemical reactions.
This same chemical reaction caused by sodium carbonate when introduced to water often causes the cloudy appearance that people recognize when a pool has been treated with this substance.
Why Add soda ash to a pool
A healthy pool requires a number of important elements such as chemical balances and sufficient heat. Sweat, grime, and pollution from swimmers and the environment make the water acidic.
This robs chlorine in your pool of its disinfecting properties, requiring you to lower the pH level to compensate for this imbalance.
When added to water, soda ash can raise that pool’s pH level and total alkalinity.
Note: It’s crucial for the health of your pool to maintain a neutral pH balance between 7.4 and 7.6 at all times.
Soda Ash Vs Baking Soda
Pool water is raised in pH with baking soda and soda ash. Therefore, soda ash raises total alkalinity faster than baking soda.
Keeping the pH of your pool stable requires total alkalinity between 80 and 120 parts per million (PPM).
If you detect too much cloudiness in your pool it’s a sign that TA is too high. You can check out AquaExact’s Pool Alkalinity Calculator for more info about how to lower alkalinity levels in swimming water.
It is therefore advisable to use baking soda if you want to raise pH rather than using soda ash on its own since it can also increase Total Alkalinity above ideal proportions. Here is guide intex pool pump not working
How To Add Soda Ash To Your Pool
To raise your pH using soda ash, follow these steps:
Making pools requires a great deal of soda ash. It comes in bags that are able to weigh up to 50 pounds and that are dissolved easily in water.
Make sure you check on the bag of soda ash and read the instructions before adding it to your pool. Some manufacturers suggest mixing soda ash with some water in a bucket first, but others only ask for you to pour it straight into the swimming pool without mixing it beforehand.
It’s important not to add these supplies near where the skimmers areas you don’t want any soda ash to get sucked through the circulation system if you have one installed.
For pool owners who want to add soda ash to raise the pH without upsetting the other levels like calcium and alkalinity, there are two ways to determine how much is necessary.
One way is by determining the desired pH level and calculating what it would take to adjust up or down, and then looking up those measurements on the container or a chart.
For those who don’t have that information available, testing can be done by adding three-quarters of the desired amount of soda ash, waiting 6 hours, and retesting pH levels as well as alkalinity, however, this method allows for a slightly more inaccurate measurement since it could potentially have had an effect on one or both of these levels.

After adding soda ash, the pool becomes cloudy
If you run into an excessive amount of cloudiness in your pool, the most likely reason for this to happen is a chemical fault. This can be due to either a too high or too low alkalinity level.
To counter this, you are expected to take measures and find a solution (which could mean lowering the PH levels).
Other possible reasons for cloudy pools include the addition of something acidic (there are many different trades that should know what’s going on), e.g. salt-water chlorination, etc.
