The correct spelling is 'caustic soda' which, when pure, contains only sodium, hydrogen and oxygen atoms. So no chlorine!
I didn't but my chlorine level is high and I don't know what to use to lower it.
You use acid & or Chlorine.
No, you use sodium thiosulfate.
Examples of products include compressed or liquefied chlorine, sodium or potassium hydroxide, sodium bicarbonate, and soda ash (not produced at mines).
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.
You should wait at least 24 hours after shocking your pool before adding soda ash. This allows the chlorine levels to return to a safe range and ensures that the pH adjustment from the soda ash is effective. Always test the water chemistry before adding any chemicals to ensure optimal results.
They can make salt, water, vinegar, CO2, and baking soda.
baking soda actually raises pH so do not use. check pH level and get that straight first.
The raw material for the manufacturing of caustic soda is sodium chloride so gas liberated at anode is chlorine.
Chlorine is typically obtained from brine water through a process called electrolysis, where an electric current is passed through the brine to release chlorine gas. It can also be obtained as a byproduct of certain industrial processes, such as the production of caustic soda.
Louisiana, New York, and Washington led all states in producing chlorine, and Louisiana and Washington also produced 44 percent of American-made caustic soda.
You don't use soda. You use Chlorine or Acid if it needs. Go to a pool supply co. & consult. they will get you set up.
