What Is Soda Ash For Tie Dye
What does soda ash do for tie dye ? What is soda ash used for? Soda ash changes the pH of the fiber-reactive dye and cellulose fiber so that the dye reacts with the fiber, making a permanent connection that holds the dye to the fiber. It actually activates the fiber molecules so that they can chemically attack the dye .
What Can Be Used In Place Of Soda Ash
What is a substitute for soda ash when tie dying? One solution is to use salt instead of soda ash to encourage the dye to bond to the fibers. Also, do you have to soak a shirt in soda ash before tie dying? Fabric Dye Fixative A viable alternative to soda ash is sodium silicate, sometimes called liquid glass.

How Much Baking Soda Should I Use
One of the potential drawbacks of using baking soda instead of a specially-packaged alkalinity increaser is that baking soda doesn’t come with pool use instructions. But don’t let that stop you from using it.
To calculate how much baking soda you should add, first determine the amount of gallons of water in your pool. Then add 1.5 pounds of baking soda for every 10,000 gallons of water to increase the pool’s total alkalinity by 10 ppm.
For example: If your pool holds 20,000 gallons of water and your test kit is showing you a total alkalinity of 50 ppm, you will want to raise your alkalinity a minimum of 30 ppm . Since the pool in this example is 20,000 gallons, every three pounds of baking soda should raise alkalinity roughly 10 ppm, which is only a third of the level you need. This means you will need to add roughly nine pounds of baking soda to a 20,000 gallon pool to raise the alkalinity by 30 ppm and achieve the minimum alkalinity goal of 80 ppm.
Add the baking soda directly to the pool, let it dissolve and give it time to distribute through your pool’s water , test, and add more baking soda if needed.
What Is Considered A Balanced Pool
Lets start at the beginning. A pools water chemistry tends to fluctuate over time. As a result, the owner may need to adjust its pH levels or its alkalinity using either soda ash or baking soda.
The ideal levels for a balanced pool will vary somewhat depending upon which expert one asks. Generally, the minimum permissible pH of a pool will range between 7.2 and 7.4. The maximum permissible pH of a pool will range between 7.6 and 7.8.
If one remembers ones high school chemistry, pH is a measure of the acidity of a solution. It depends on the concentration of hydrogen ions in the solution. Numerically, it can range from 0 to 14. Everything below 7 is considered acidic. Everything above 7 is considered basic. And 7.0 is neutral.
The above pH ranges for swimming pools are considered slightly basic.
The alkalinity of a solution, in this context, is a measure of the pool water to resist acidification. It is measured in parts per million . Generally, the alkalinity of pool water should range somewhere in the neighborhood of 80 to 120 ppm. The alkalinity range is useful in keeping the pH stabilized so it does not suffer from wide erratic swings.
The idea for swimming pools is to maintain a pH that serves as some kind of disinfectant . It needs to be strong enough to kill germs without damaging the skin or eyes.

How To Add Soda Ash To Your Pool
Before you start handling soda ash for your pool, its essential to wear your gloves and eye protection, as you dont want pool cleaning chemicals coming into direct contact with your skin. You will also need a bucket and something to mix the chemicals with water any kind of typical stirring stick should work.
Before you begin, you should also test the chemistry in your pool water to figure out exactly how much the pH levels and alkalinity need to be adjusted. You can accomplish this with test strips or, for greater accuracy, a liquid or digital testing kit. These are often more expensive but will give you the pH and alkaline levels to the decimal point, which will allow you to be much more precise with the amount of soda ash you add.
Once you know how much soda ash you need, the next step is to collect some water from your pool in the bucket. Youll need to read the soda ash product packaging carefully to determine the correct dosage required to achieve the pH balance you need for the size of the pool you have. Add the correct amount of soda ash to the water bucket and mix thoroughly. Its essential to ensure that the soda ash is completely dissolved before its added to the pool. Otherwise, the chemicals may cause cloudiness.
Summary: Soda Ash Vs Baking Soda
Soda ash and baking soda can both be used to raise a pools pH and total alkalinity levels, but they work in opposite ways.
Soda ash will raise pH and minimally raise alkalinity, while baking soda will raise alkalinity and minimally raise pH.
Use baking soda when the pH isnt off by much, but the alkalinity is way too low, and use soda ash when the pH needs to be drastically increased but you want the alkalinity to be less affected.

Keep An Eye On Alkalinity
Are your pH levels still too low after adding in the soda ash? Try testing the alkalinity of your water!
If the pool waters alkalinity is too low, the pH of your pool water will fluctuate. Your waters alkalinity should be between 80 ppm and 150 ppm!
Once youve discovered that your pools alkalinity is too low, add in 1.4 pounds of baking soda for every 10,000 gallons of water in your pool.
Let the baking soda circulate through your pool with the pump turned on for around one hour before you test the alkalinity again. Not only does baking soda increase the alkalinity of your pool water, but it also raises the pH levels!
However, be aware that youre not adding too much baking soda into your pools water. If youre adding in baking soda after youve added in soda ash, know that soda ash also increases the alkalinity in your pool. Its much harder to lower your alkalinity levels than it is to raise them!
What Does Baking Soda Do For Pools
Baking soda , also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient.

How Does Soda Ash Work
To raise the pH of water, a substance must take away a hydrogen . Soda Ash works by stealing a hydrogen atom to become bicarbonate. When Soda Ash snags a H+, the reaction looks like this:
Na2CO3 + H+ 2Na+ + HCO3-
Soda Ash + Hydrogen yields Sodium and Bicarbonate
This all ties into the broader discussion about alkalinity and pH. We know in the pool business that alkalinity is a pH buffer, but do we know why? In a less-than-scientific explanation, alkalinity buffers pH by either donating a Hydrogen or absorbing one. Alkalinity makes it more difficult for pH to fluctuate quickly.
Specifically, carbonate ions like to become bicarbonate, and vice versa. When you add Soda Ash to the pool, the carbonate anion wants to become bicarbonate . To do so, it needs to get a Hydrogen from somewhere. When carbonate takes its Hydrogen atom, the pH goes up. This pH and alkalinity chemistry is about equilibrium, so the opposite is also true. When you add acid to the pool, a Hydrogen is released and the pH goes down. Its all about the hydrogen ions.
Now that we know what Soda Ash is and how it reacts in water, lets talk about why it sometimes clouds up a pool.
Whats The Difference Between Baking Soda And Soda Ash
Baking soda and soda ash are sometimes confused because they serve similar purposes. When added to a pool, each one will raise both the pools pH as well as the pools total alkalinity levels. What differs in each case is the degree to which each one raises each factor.
Baking soda is more effective at raising the alkalinity of a pool. It will also raise the pH, but not by much. Soda ash is just the reverse. Soda ash is very effective at raising the pH of a pool. It will also raise the alkalinity of a pool, just not by much.
This is all a result of the differing pH levels of the two products. Baking soda has a pH of around 8 while soda ash has a pH of around 11.3 to 11.7. That might not sound like a big difference , but it is. The pH scale only goes up to 14 and it is logarithmic in nature. That means that a difference of 1 indicates a difference of 10 times.
So, following that rate of change the difference between 8 and 9 is 10 times, the difference between 9 and 10 is 10 times, and the difference between 10 and 11 is another 10 times. As a result, the difference between 8 and 11 on the pH scale is about 1000 times. So soda ash is far more potent than baking soda on the pH scale .

When To Use Baking Soda
When determining whether to use baking soda or soda ash to balance out your pools pH and total alkalinity, its essential to understand what these numbers should look like.
The ideal pH level for your pool is 7.2 to 7.8. That way, the water maintains a good balance of an ideal pH for disinfection without hurting your eyes and skin.
Total alkalinity correlates with pH because the higher the pH, the more alkaline the water. Alternatively, the lower the waters pH is, the less alkaline itll be. Nevertheless, as youll soon learn, the pH and total alkalinity balance can get thrown off.
So, lets look at how these numbers correlate to you and your pool when using baking soda.

How To Use Soda Ash In Your Pool
Maintaining the delicate pH balance of your swimming pool can be challenging and usually requires a highly specific mix of chemicals for sustained clean water. If testing the water chemistry of your pool reveals too much acidity for safe swimming, soda ash also known as sodium carbonate may be an excellent solution to restoring a healthy balance.
So, what is soda ash, how does it compare to similar options, and how do we use it? Lets dive in.
Does Soda Ash Make Pool Cloudy
The high pH of Soda Ash itself can create a high-LSI violation in its immediate vicinity. It drastically raises the pH in the water around it, which leads to clouding. This explains why the cloudiness does not happen all at once, rather the process creates a cloudy plume that slowly expands across the pool .

. Similarly, what is soda ash and what is it used for?
Soda ash, also known as sodium carbonate, has the following uses: Industrial applications Being a highly soluble substance, soda ash is used for numerous chemical reactions. It’s mostly used as an ingredient in the manufacture of dyes and coloring agents, synthetic detergents and fertilizers.
is baking soda the same as soda ash for pools? The industry standard has always been to use sodium bicarbonate to raise total alkalinity and sodium carbonate to raise pH the exception being if both total alkalinity and pH are low. Sodium carbonate will actually have a dramatic effect on both pH and total alkalinity.
In respect to this, how do you use soda ash in a pool?
Just add 1lb of Soda Ash for every 10,000 gallons in your swimming pool. Keep your pH and Total Alkalinity balanced with ease and efficiency when you use our Soda Ash.
How much soda ash should I put in my pool?
See if the pH is in the range you need it to be. Add more soda ash as needed. You generally don’t want to add more than one pound total of soda ash per 10,000 gallons of water. If you add more than that, the water starts to become cloudy.
How To Fix ‘milky’ Pool Water
Many of us may have had the unfortunate experience of adding soda ash “wrong” to pool water, resulting in a pool that looks like it is filled with milk. In fact, we refer to it as “milking” a pool. Why does that happen?
When we decide, for example, to raise the pH of a pool from 7.2 to 7.6, we calculate how much soda ash is required for that size pool to achieve a 0.4 pH unit increase. A solution of soda ash has a pH of above 11, so when added to pool water the pH goes up and raises the alkalinity too. But when we figured a dose, that pitcher full of powder is ideally supposed to be immediately distributed throughout the entire pool. When we walk to the shallow end and just dump the entire pitcher-full in a single slug, we may temporarily have a small amount of water, 20 or 30 gallons worth, with a pH in the 10 range.
What does that do to the water? Well, the soda ash is normally very soluble in the water. It goes into solution almost immediately, but it also raises the pH and the saturation index high enough to cause calcium bicarbonate to precipitate. The white cloud you see is not actually the soda ash, but precipitated calcium carbonate.
When we dump a large slug of soda ash into the pool, we temporarily create a small area of high pH, perhaps in the 10 range, which causes precipitation of calcium carbonate.
When a pool is milked, we explain the situation to the customer and lay out two choices: We can either re-dissolve the calcium or filter out the precipitate.

We recommend using this approach because it requires less manipulation and is safer for beginners. The main drawbackis that it will exhaust the dye solution if its not used quickly.After a few hours, the dye will lose strength and the color will benoticeably paler. Definitely use the dye if its been mixed with soda and dont try to store it for future use.
Is Soda Ash Good For Pools
Soda ash is the chemical compound one should use to increase the pH of the water in a pool. Chemically speaking, soda ash is known as sodium bicarbonate. On its own, it has a pH ranging between 11.3 and 11.7. This is dramatically higher than the mere 8 of baking soda.
Because of that, it is the preferred substance to be used to raise a pools pH. So, yes, it is perfectly good for poolsif the goal is to raise the pH. For example, one can raise the pH level of a 10,000 gallon pool by as much as 0.2 using only 6 ounces of soda ash. At the same time, this will only increase the total alkalinity by 5 ppm.
Soda ash is perfectly safe for pools when used properly .

Tips For Adding Baking Soda Effectively
Get ready to buy baking soda in bulk for it to work effectively, youll need to use approximately 1.5 pounds of baking soda for every 10,000 gallons of water in your pool. Let me put that into perspective for youeven a small above-ground pool often holds over 13,000 gallons of water. For more exact measurements for your pool, use my alkalinity calculator.
Although you can technically pour dry baking soda straight into your swimming pool, I recommend mixing it with water first so that it forms a thin paste. That way, you can smooth out any clumps before you pour the substance into your pool, helping it disperse faster.
While Im on the topic of dispersion, a little trick is to pour any substances that youre using to maintain your pool by the return jets. That way, itll move the baking soda around your pool faster.
Nevertheless, you can expect it to take around six hours for the baking soda to mix into your pool fully. After these six hours, you should retest the total alkalinity and pH of your water.
If the numbers arent as good as you want them to be, continue adding more baking soda until youre satisfied with the results. However, be careful not to add too much so that you dont run into adverse side effects.
