Muriatic acid will not lower the Harness(calcium chloride)level in a swimming pool. Dilution is the only effective method to lower the calcium hardness level. Muriatic acid is used to lower the pH and total alkalinity of pool water.
If it is added in small quantities, through the filtration system(via: an acid pump), and only to maintain proper pH, then no. pH adjustments should still be done when thereare no swimmers present.
Of course to lower the PH or Alkalinity but I suggest you cut 4-1 with your pool water and disperse throughout pool.
It can be used to remove rust stains caused by swarf or some metalic object lef laying in the pool. however if the rust is a result of reinforsement having come in cotact with the water No.
At normal levels - no.
Hydrochloric acid is most commonly known as muriatic acid and is used to lower pH in pools
Usually you would add muriatic acid to adjust the pools acid level.
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.
You can add dry acid to your pool when your pH is above 7.8
NO!!! Never add them at the same time, together they make a toxic gas A general rule when adding chemicals to pools is to wait at least an hour before adding any other chemical to the pool. Remember Muriatic acid is very dangerous so be careful bad for lungs, burn skin, blind eyes.
You can't! Muriatic acid (~32% HCL) will not add any free chlorine to the pool and will not function as a oxidizer (Shock).
Muriatic acid added to the pool water will not remove stains from swimming pools. Unless you do an acid wash. Something that should be left to an experienced pool tech. Purchase a good test kit that will measure chlorine, pH, alkalinity and conditioner. This test kit will, after the initial test for pH and with a further test, give you amounts of muriatic acid to add to your particular size, in gallons, pool. K
use either muriatic acid or dry acid (sodium bisulfate)
None until you add it.
The original question was the better of the two questions. Is it ok to add muriatic acid while the pool is in use? When is the best time to add muriatic acid? You should either wait until no one is going to use the pool for a while. It is not a good idea to add chemicals to the pool while someone is in it. Best to add chem. first thing in a.m. before use - then let circulation distribute those chem. k
When mixing acid and water, always add the acid to the water, and add it slowly. Never add the water to the acid.
Add acid, Muriatic acid works best but Dry Acid is also used.
