Pool Vinyl Muriatic Or Dry

Muriatic acid contains hydrochloric acid concentration levels between 28 to 35 percent.

Pool vinyl muriatic or dry.

This granular form of acid is safer and less caustic than muriatic acid. Being in this form also eliminates spilling or splashing so its safer and easier to use. 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. Also dry acid is costlier than muriatic acid.

The main use for muriatic acid in a pool is to lower ph balance. 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. 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. 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. 1 cup of muriatic acid is the same as 10 8 ounces weight or about 7 2 ounces volume of dry acid. Sodium bisulfate is commonly known as ph down or ph minus in pool stores. 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.

Worse the slug of muriatic acid can do major even catastrophic damage to your pool. Keep it out of the reach of children and pets in a cool dry area. But it is worth the extra pennies due to the safety it brings. 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.

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. 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. It comes in granular forms and is safer to handle than muriatic acid.
