How much muriatic acid needs to be added to salt water pool?

Answer 1

the optimal level is between 7.4 and 7.6. For a 1,000-gallon pool, add 1.5 oz. if the pH is between 7.8 and 8, 2.5 oz. if the pH is between 8 and 8.4, and 3 oz. if the pH is above 8.4. For a 5,000-gallon pool, add 8 oz. if the pH is between 7.8 and 8, 12 oz. if the pH is between 8 and 8.4, and 16 oz. if the pH is over 8.4. For a 10,000-gallon pool, add twice as much as you would for a 5,000-gallon pool to restore pH to the optimal level.

Answer 2

It depends on what your starting pH is. Your target range is 7.2 - 7.8. If your test shows a reading higher than that, add 1/2 gallon muriatic acid. Retest 24 hours later. Repeat daily until you are in the target range. Thereafter, you should be able to test and adjust once a week. Muriatic acid is not the only chemical to be added at start up. It would be best to take a pool water sample to a pool supply company. Most companies now have computerized testing that will printout current levels of chemicals, as well as how much and what order to add to your pool water. They may try to "add on" sales of algaecide, phosphate remover, etc. The only chemicals you need to start up your pool are stabilizer, shock, chlorine tabs, and possibly soda ash or sodium bicarb.

Answer 3

You will only have to add acid if your pH is too high. Add enough to bring the pH down to 7.2. Do it gradually and test with an OTO water tester after waiting at least a day after each adjustment. Hatawa

26 fluid ounces of Muriatic acid (31.4%) will decrease the alkalinity in 10,000 gals by 10ppm.

Answer 5

none until you add some
