How often should you put muriatic acid in your pool?

If you have a pH reading of 7.8 or higher, and an average size (15,000 gallons) in-ground pool, you should add 1/4 gallon (a quart) of muriatic acid, and re-test after the water has circulated for an hour.

How often should I add muriatic acid to my pool?

We recommend adding Acid weekly! Adding a little and often is better for your water and can actually save you money overtime. Large doses over longer periods of time take a larger portion of your 'Total alkalinity' away.

What happens if you put too much muriatic acid in pool?

If you do add too much muriatic acid, your pH levels can dip dangerously low, and your pool water can cause rashes and eye irritation. Low levels of pH can also damage metals in your pool like ladders, railings, screws, bolts, and other important equipment.

How long does muriatic acid last?

Sodium Bisulfate and muriatic acid could have a 5 year shelf life, however pH decreasers are acids, and a larger shelf life concern about pH decreasers is the strength of the container. Over time, thin plastic bottles or packaging can break down from contact with acids.

Can you add muriatic acid directly to the pool?

Yes, you can add muriatic acid directly to your swimming pool water. But it's safer if you dilute it in a bucket of water first. If you do want to add it directly to your pool, pour it into the deepest part of the pool, walking away as you pour so you don't inhale any of the fumes.

How To Add Muriatic Acid To A Pool To Lower pH

Will muriatic acid clear a cloudy pool?

Cloudiness Due to Elevated pH

Before you floc the pool, you should check the chemical balance, and if you notice the pH is too high, that may be why the pool is cloudy. You may be able to clear the water by adding muriatic acid to lower the pH.

Do you run the pump when adding muriatic acid?

Turn the pool on

By having the pump on it will aerate the pool, slightly increasing pH and aiding alkalinity. Therefore, adding muriatic acid to the pool while the pump is running will reduce the likelihood of large drops in pH.

What does muriatic acid do for a swimming pool?

Along with balancing the pH levels of your pool water, muriatic acid is strong enough to kill mold, remove rust stains, get rid of calcium deposits, and clean the surfaces of your pool.

How much muriatic acid can I add to my pool at one time?

Usually 2 cups of muriatic acid in a 24 hour period is safe to add to a pool at the one time. Factors determining how much acid to add are how strong the muriatic acid is and the volume of your pool. The stronger the muriatic acid (aka Hydrochloric Acid) is, the less you can add at once.

Will muriatic acid lower hardness in pool?

Try muriatic acid.

It won't actually reduce the water's calcium hardness, but it will raise the saturation level, which can help bring the water back into balance.

Can I add chlorine and muriatic acid at the same time?

Perhaps most important note of all, never add chlorine and muriatic acid together in the pool. This creates a dangerous toxic gas that can have severe health consequences if inhaled.

How long does it take muriatic acid to lower pH?

It will take 24 hours for the muriatic acid to react with the existing balanced pool water. Remember never to pour muriatic acid into your pool. Dilute part of the muriatic acid in a bucket of balanced pool water, and then pour it into your pool. "Dilution is the solution," Dukes says.

When should I add acid to my pool?

If you have a pH reading of 7.8 or higher, and an average size (15,000 gallons) in-ground pool, you should add 1/4 gallon (a quart) of muriatic acid, and re-test after the water has circulated for an hour.

How long do I wait between adding pool chemicals?

Wait times for adding pool chemicals

The wait times between adding pool chemicals is usually around 10 minutes each, as that is also sufficient time for the chemicals to mix in the water. Users also under normal conditions can swim roughly 10 minutes after adding chemicals.

Does Shocking a pool lower alkalinity?

Another cause for high alkalinity can be when you shock the pool. While this is performed to quickly rid the pool of pollutants, chlorine-based pool shock is highly alkaline, and can raise the water's total alkalinity level in the process.

What is the harmful effects of muriatic acid?

Chronic Exposure Effects on Health

Long-term exposure to muriatic acid vapors has been known to cause corrosion of teeth and severe lung damage leading to chronic bronchitis. Additional symptoms include gastritis; lesions in the trachea, nasal cavity, and larynx; photosensitization; circulatory failure, and death.

Should I run the filter after adding muriatic acid?

You want to make sure the pump is running for at least 1/2 hour, preferably even an hour, during and right after after adding most chemicals. Running the pump longer than 1/2 hour is just fine, particularly if you would normally have it running anyway.

Will baking soda lower pool alkalinity?

Baking soda, also known as sodium bicarbonate is naturally alkaline, with a pH of 8. When you add baking soda to your pool water, you will raise both the pH and the alkalinity, improving stability and clarity.

How do you remove sediment from bottom of pool?

If there has been a serious invasion of excess dirt and debris, you may also need to shock your pool. Vacuuming is recognized as the only way to remove sediment from the bottom of a pool.

How do I clean my pool with muriatic acid?

Pool acid washing is a process where chemicals—mainly hydrochloric acid, also known as muriatic acid—are combined with water and are sprayed onto your pool's surface to remove any grime and build-up. A professional pool cleaner will then use a brush to scrub out the staining and other grime.
