Pool Vinyl Muriatic Or Dry
Dry acid is also known as sodium bisulfate.
Pool vinyl muriatic or dry. 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. Keep it out of the reach of children and pets in a cool dry area. 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. 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.
The main use for muriatic acid in a pool is to lower ph balance. 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. 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. Yes this is total b s.
Being in this form also eliminates spilling or splashing so its safer and easier to use. Muriatic acid contains hydrochloric acid concentration levels between 28 to 35 percent. Also dry acid is costlier than muriatic acid. Sodium bisulfate is commonly known as ph down or ph minus in pool stores.
It comes in granular forms and is safer to handle than muriatic acid. But it is worth the extra pennies due to the safety it brings. But it s also a great chemical to have on hand for heavy duty scrubbing when scaling and calcium deposits are a problem. 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.
The main thing to remember is to use extreme caution when handling and storing this chemical. Worse the slug of muriatic acid can do major even catastrophic damage to your pool. This granular form of acid is safer and less caustic 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.
