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.
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
You can't! Muriatic acid (~32% HCL) will not add any free chlorine to the pool and will not function as a oxidizer (Shock).
use either muriatic acid or dry acid (sodium bisulfate)
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
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
When mixing acid and water, always add the acid to the water, and add it slowly. Never add the water to the acid.
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.
Add muriatic or hydrochloric acid.
No, you should not add muriatic acid and a product labeled as "no phos" (phosphate-free) at the same time. Muriatic acid, which is a strong acid, can react with other chemicals, potentially causing harmful reactions or reducing the effectiveness of the other product. It's best to add them separately and allow time for the first chemical to disperse before introducing the second. Always follow safety guidelines and product instructions when handling chemicals.
To lower the pH of your pool from 8.2, you can add muriatic acid or sodium bisulfate. Follow manufacturer guidelines and test the pH frequently to ensure it is within the recommended range of 7.2-7.8 for swimming pools.
