Also dry acid is costlier than muriatic acid.
Pool vinyl muriatic or dry.
It is recommended that you get to check the ph level after allowing the pool water to circulate and settle for an hour.
Yes this is total b s.
Worse the slug of muriatic acid can do major even catastrophic damage to your pool.
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.
Dry acid is also known as sodium bisulfate.
Sodium bisulfate is commonly known as ph down or ph minus in pool stores.
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.
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.
Muriatic acid contains hydrochloric acid concentration levels between 28 to 35 percent.
The main use for muriatic acid in a pool is to lower ph balance.
Being in this form also eliminates spilling or splashing so its safer and easier to use.
Even diluted muriatic acid can potentially cause harm.
Keep it out of the reach of children and pets in a cool dry area.
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.
But it is worth the extra pennies due to the safety it brings.
It comes in granular forms and is safer to handle than muriatic acid.
1 cup of muriatic acid is the same as 10 8 ounces weight or about 7 2 ounces volume of dry acid.
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.
This granular form of acid is safer and less caustic than muriatic 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.
