baking soda is the chemical that is used to raise your pH and alk. when both of these are in range they "buffer each other" which means it usually will stay constant.
I also use baking soda...Sam's Club sells it in 12lb bags...it usually has a 'key' on the back of the bag of how much to use for what size pool.
It also helps your skin stay soft from the swim!
Baking Soda is great if you need to raise BOTH the pH and the alkalinity at the same time.
If your alkalinity is at the correct level, and your pH is low, you do not want to raise the alkalinity, so do not use Baking Soda.... Instead, use "20 Mule Team BORAX" - half a box at a time, wait a couple of hours and re-test each time.
Make sure you buy the "20 Mule Team BORAX" and not any kind of Detergent with Borax in it. That will give you a mess.
The "20 Mule Team BORAX" can be found in the Laundry Additives section in your local super market for a fraction of the cost of the pH-up products, and will work wonderfully without raising your alkalinity to harden your water too much. It also leaves your skin soft after a swim, like the Baking Soda.
Here's a link to show the use of 20 Mule Team Borax in your pool to raise the PH without affecting the Alkalinity levels:

Assuming your talking about soil PH, applying wood ash or agricultural lime in suitable quantities will do the trick. Both are highly alkaline.
Your pH is the opposite side of the same coin with alkalinity.
To raise it use Sodium Bicarb. With the pump motor off and water motionless, add the bicarb in the deep-end of the pool, in one spot.
Let it sit for 4 hours or more. Turn the pump on and allow to circulate for 2-3 hours, then re-test. Alkalinity should be 80-100, not 150 or higher.
To lower alkalinity, do the same, just use acid. The chart your need in provided in the link below.
You can raise pH only by using sodium carbonate which is mostly sold as pH plus. Don't use bicarbonate which will raise pH but also raises the alkalinity.

Your alkalinity is really high How do you lower it without lowering the pH too?
pH refers to the level of acidity or alkalinity. less than 7 is acidic, more than 7 is alkaline. if you want to lower your alkalinity, add muriatic acid. It will lower the pH though
How do you lower alkalinity but not change pH in a swimming pool?
To lower alkalinity without affecting pH levels in a swimming pool, you can use muriatic acid or sulfuric acid. These chemicals will reduce alkalinity without impacting the pH significantly. Be sure to follow the manufacturer's instructions and test the water regularly to maintain proper balance.
What are the alternatives to using muriatic acid to lower the PH in a swimming pool?
There are 3 principal chemicals for lowering pH: muriatic acid, sodium bisulfate (dry acid) & CO2. If this is a commercial application then CO2 may be a viable source. The sodium bisulfate is dry acid which when mixed with water makes liquid acid but does not have the odor. Muriatic acid and sodium bisulfate both lower total alkalinity at hte same time as lowering the pH. CO2 may raise total alkalinity at the same time as lowering pH. The total alkalinity is important to have a stable pH which in turn is important to have a relatively constant pH for the proper effectiveness of the sanitizer (chlorine) Any other questions feel free to email me direct.

Can you use sodium bisulfate to lower TA?
Yes, sodium bisulfate can be used to lower total alkalinity (TA) in swimming pool water. It reacts with the alkaline substances in the water, reducing the TA levels. It is important to follow manufacturer's instructions and dosing recommendations when using sodium bisulfate.
How do you lower alkalinity of wastewater secondary effluent without dropping pH?
The Ph should never be out of its permitted range. the alkaline tunity wastewater is tested on three stages. There should never be less than 50 mg/L of alkalinity.
How does the pH value vary with the strength of acidity and alkalinity?
pH is a measure of the acidity or alkalinity of a solution on a scale of 0-14, with pH 7 being neutral. Lower pH values indicate higher acidity, while higher pH values indicate higher alkalinity. Strong acids will have a pH closer to 0, while strong bases will have a pH closer to 14.
Why is sodium bisulfate used in a pool?
It is used to lower both ph and alkalinity.
How could HCI be used in a swimming pool?
To adjust pH and/or lower alkalinity.
How do you lower the PH Alkalinity in a above groun pool?
use muratic acid to bring down Ph and TA
What will reduce strong alkalinity without drastically increasing PH in pools?
pH and Alkalinity/Acidity are functions of each other. pH's above 7.0 are considered alkaline and pH's below 7.0 are considered acidic. So reducing the alkalinity will by it's very nature reduce the pH of the pool.
How do you lower alkalinity and raise pH?
To lower alkalinity, you can add muriatic acid or sodium bisulfate to your pool water, following the manufacturer's instructions. To raise pH, you can add soda ash or baking soda to the pool water. It's important to regularly test the water after adding chemicals to ensure you achieve the desired levels.
Does Co2 lower alkalinity?
Yes it does. Some pool management systems use CO2 to lower the pH of the water. Of course if it is used regularly the Alkalinity will soon fall. Michael
