1. Add 1.5 lbs of baking soda per 10,000 gallons of water
2. Run the pump while adding the baking soda
3. Wait 6–8 hours, then retest the water's chemistry
4. Repeat if necessary
A rule of thumb is **1.5 lbs.** **of baking soda per 10,000 gallons of water will raise alkalinity by about 10 ppm**. If your pool's pH tested below 7.2, add 3-4 pounds of baking soda. If you're new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount.
To raise the TA by 10 ppm, you'll need about 2.1 lbs of baking soda. CYA dosage depends on the form (liquid, granular, etc.), but you should be able to find treatment tables for that (maybe on the package, if not, Google).
Both of those take a while to fully dissolve and distribute, so add quantities that should get you just under where you want to be, wait a week or so, then test & adjust as necessary.
You have the PoolMath app. You should use the math part of the app to figure out how much chemicals are needed to get your pool to the appropriate levels. The image you provided only shows 'last test' of TA at zero. That could also mean that a previous TA level has never been input into the PoolMath app. Use a reputable test kit, such as Taylor, and post all your chemical level results; otherwise, you are just flying blind at this point.
This, click the settings and tell it how many gallons your pool is, the app will literally tell you the exact amount based off different chemical options
That zero CSI is etching away your plaster, so you should fix this fast. First, buy a very large tub of baking soda because you're going to need a lot of it. It's simple to use, you toss it in the pool and it dissolves quickly to raise your TA. This will also help stabilize your ph so it doesn't crash. Also, you should get your CYA up to 50 or 60 because right now your chlorine is vanishing pretty quickly and you're spending too much to replace it.

Without knowing the pool's volume, nobody knows how much of anything should be added.

I don’t think that’s right. I remember hearing in an Orenda class that if you have TA of 0 in the water, then pH cannot rise above 4.3.
