Yes, but it's not generally a good idea. Both will tend to raise your pH. If your pH is too low, add the borax first, to get it to at least 7.0. Then you can add baking soda, if you need to increase your alkalinity. BUT, you should check your alkalinity after you raise your pH -- it will be higher, and you may not need the baking soda.
You can use baking soda to raise the pH level in a hot tub, however soda ash will work better. Borax even better than that. The issue with baking soda is that it more readily raises Total Alkalinity so will have a larger effect on TA rather than pH.
Yes, it is soduim bicarbonate, just like the chemical at the pool store
Raise pH
In some cases, soda ash can be used to raise total alkalinity. Pound for pound, soda ash raises alkalinity 60 percent more than sodium bicarbonate and is cheaper than sodium bicarbonate. The problem with using soda ash to increase alkalinity is it drastically increases pH. This can cause cloudy water and scale formation. Soda ash should only be used to increase total alkalinity if you also need to increase the pH or if only small increases in alkalinity are needed.
Chlorine will not raise the total alkalinity level in a pool. However, if you are trying to raise the total alkalinity, you can add small amounts of baking soda.
Baking soda.
Baking soda will not soften (remove calcium hardness) from pool water. It will raise total alkalinity.
Alkalinity is common baking soda. Hatawa

Use Soda Ash to increase the PH level. Baking soda can be used to maintain the alkalinity of the pool water. Just the opposite!!!! Baking Soda will increase or raise the alk. Soda Ash raises the pH. Muriatic Acid lowers pH. k
You can (soda ash is used to adjust PH) but your pool supply store may have a cheaper alternative. I used "Alkalinity Increaser" for a year or two until I noticed that the sole ingredient is baking soda. I have heard since that the only difference is that the kind you buy in the grocery store is finer than the pool version (which is good because it's easier to dissolve). I also buy my baking soda at a wholesale club, where it costs a fraction of "Alkalinity Increaser" at a pool store. I agree. I needed to add 25 pounds of pH plus to my pool. At the pool supply it was $12.50 for 4 pounds. At my local Dollar General, it was 50 cents a pound. True, I had to buy 25 boxes but my son had fun ripping them open and throwing the baking soda all over the pool! It usually dissolved before it hit the bottom! I am told by my local pool, expert that using baking soda in place of 1 or 2 pounds of Alkalinity Up is OK but for larger amounts, it may make the water cloudy because baking soda has larger granules than Alkalinity Up.

Soda ash, which can also be referred to as washing soda, is sodium carbonate. Baking soda is sodium bicarbonate.
The most commonly sold product for that purpose is sodium carbonate, aka soda ash, sold as Ph Up by pool stores and as "Washing Soda" by grocery stores.You can also use 20 Mule Team Borax Laundry Booster (sodium tetraborate). It can be found at many grocery stores. Try using the same amount as you would with PH plus 1 lb. to 10,000 gallons, and wait 2 to 4 hrs. Then check your PH reading. If it's still low, add some more until you get it to 7.2 to 7.8 range.Caution - check your alkalinity before using borax, because borax raises PH only, without affecting your alkalinity much. If your alkalinity is also low you can use baking soda (sodium bicarbonate) to raise your alkalinity and PH. Baking Soda raises PH and Alkalinity at the same time. Baking Soda has the same ingredients as Alkalinity plus, but half the price. Take a look at this web site for more information on Borax: www.poolsolutions.com/gd/borax_20mule.html

Baking Soda from your grocery store works the same as the Bicarb the pool stores sell to raise PH. The local Wal-mart sells 8 lb bags for close to a dollar a pound. Shop for your best price. Be aware that baking soda will raise your alkalinity as well.
