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.
add acid
Add acid
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.
use either muriatic acid or dry acid (sodium bisulfate)
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)
Most likely not.
Acid dilutes very fast, add it to your pool (while running to help circulation) and you should be ready to swim in about 30min. Best way to add it is by using a 5gal bucket, fill it so that you have room to add the acid then walk around the pool pouring into the edges of the pool. This will keep from damaging your plaster especially if your pool has dark plaster or pebble tech plaster. Hope you found this helpful..
