acid is added to a pool when alkalinity is too high. Take a sample of pool water to your pool shop and have it tested by them. they will tell you what is required.
Yes you can the muriati acid is used to get the pools pH to between 7.2 and 7.6 then you can add the pool shock as per the instructions.
Remove some water in container (10-20%) and add new water. example: pump water high in cyanuric acid out of a swimming pool and the add fresh water to the pool.
Add acid
add acid
use either muriatic acid or dry acid (sodium bisulfate)
To raise the pH of your pool you add soda ash (sodium carbonate). To lower the pH of your pool add muriatic acid (hydrochloric acid) or sodium bisulfate. You should always add chemicals with the pump running and check your levels again once the newly added chemicals have been circulated around the pool.
Yes, you are supposed to add it while there is water in the pool. Add with filter running near a return line. Add it slowly and if possible, brush the pool to help mix the acid. You can swim within 30-60 minutes.
add more acid
you have to aid a conditioner or stabilizer with cynaric acid in it.
You can't! Muriatic acid (~32% HCL) will not add any free chlorine to the pool and will not function as a oxidizer (Shock).
Reduces alkalinity of swimming pool water (softens hard water)
Hydrochloric acid is most commonly known as muriatic acid and is used to lower pH in pools
