On the bottle it should tell you how much per gallon of water, also it depends on how bad your pool is. If you're really unfamiliar, you better get the pro's, unless its a small seasonal pool, then I go with not enough chemical, go light because you don't want anyone to die in it.
It depends on the volume of your pool and what level your Ph is at.

first you must test for ph with a ph testing kit, then if the water is a good ph level, add 2L chlorine for every 100L, then wait for 2 days, then get in the pool and it should be fine! ;) my number's: 0473897234
It lowers PH
a swimming pool it should be neutral pH ie green
Pool alkalinity refers to the ability of the water to resist changes in pH levels, while pH measures the acidity or basicity of the water. Alkalinity helps stabilize pH levels, as it acts as a buffer. Maintaining proper alkalinity and pH levels is crucial for the overall balance of a swimming pool, as it ensures water clarity, prevents corrosion of pool equipment, and provides a comfortable swimming environment.
add a PH reducer chemical
Everythging works better when the balance is correct, but you do not need to correct the pH before adding chlorine. Just keep an eye on it.

Using sodium bicarbonate to lower pH in a swimming pool is not effective. Sodium bicarbonate, or baking soda, is typically used to raise pH levels in pools. To lower pH in a pool, an acid such as muriatic acid or sodium bisulfate should be used.
The best way to find out what pool supplies you will need is to go to your local pool store and speak to a worker there. You should remember to ask when chemicals will be needed to keep your Ph in balance.
