Even diluted muriatic acid can potentially cause harm.
Pool vinyl muriatic or dry.
Adding muriatic acid directly to your pool can create a hot spot of acid that can potentially burn or irritate the skin if you swim too early.
Worse the slug of muriatic acid can do major even catastrophic damage to your pool.
But it is worth the extra pennies due to the safety it brings.
Muriatic acid contains hydrochloric acid concentration levels between 28 to 35 percent.
It is recommended that you get to check the ph level after allowing the pool water to circulate and settle for an hour.
But it s also a great chemical to have on hand for heavy duty scrubbing when scaling and calcium deposits are a problem.
Also dry acid is costlier than muriatic acid.
Sodium bisulfate is commonly known as ph down or ph minus in pool stores.
Dry acid is also known as sodium bisulfate.
If that slug comes to rest on a vinyl liner with its 30 concentration of hydrochloric acid it can dissolve your liner or weaken it enough to fail.
In most cases you will have to add a quart of muriatic acid for an average size ground pool holding about 15000 gallons and has a ph level higher than 7 8.
Muriatic acid 31 45 hydrochloric acid and dry acid 93 2 sodium bisulfate are both strong acids and have identical effects on pool water when using comparable amounts.
1 cup of muriatic acid is the same as 10 8 ounces weight or about 7 2 ounces volume of dry acid.
There are other acids in the pool business such as cyanuric acid and citric acid but they are not used for adjusting ph or alkalinity levels.
Keep it out of the reach of children and pets in a cool dry area.
It comes in granular forms and is safer to handle than muriatic acid.
The three acids used for ph and alkalinity management are muriatic acid hydrochloric or hcl sulfuric acid h 2 so 4 and a dry acid called sodium bisulfate nahso 4.
Our dry acid buckets include a granular form of acid that helps lower ph maintain balanced water and total alkalinity in your pool or spa.
The main thing to remember is to use extreme caution when handling and storing this chemical.
Being in this form also eliminates spilling or splashing so its safer and easier to use.
