What Happens If You Put Too Much Muriatic Acid In A Pool?

One of the most useful chemicals for swimming pools is muriatic acid. When wanting to own a pool, you may possibly think, “Well, I’ll just add some chlorine and my pool will run at full capacity and efficiency.” The reality of pool owners’ maintenance is a little bit more complex than we think. 

Muriatic acid is frequently used to thoroughly clean and degrade the buildup found in pool filters. If you observe an excessive amount of algae growth that you can’t seem to get rid of, muriatic acid would do the eliminating job perfectly.

You can also use it to scrub the pool’s walls. Also, when pH and alkalinity levels get too high, muriatic acid of the same type can be put directly into your pool to decrease them.

It is essential to maintain the pH levels in the ideal range for your chlorine sanitizer to function. For this reason, it’s crucial to add the proper quantity of muriatic acid to your pool.

The pH levels in your pool water might drop dangerously low and cause rashes and eye discomfort if you add too much muriatic acid. Low pH levels can also corrode metals in your pool, including ladders, railings, screws, and other crucial pieces of equipment.

To restore the proper pH balance in your pool, if you add too much muriatic acid, you might need to add soda ash or sodium carbonate. Changing pH levels by repeatedly using chemicals can be expensive and inconvenient.

How do I lower the pH in my pool with muriatic acid?

A high pH in the water can result in hazy water, skin rashes, and scaling on pool equipment. Scaling inside pipes may accumulate over time, reducing water flow and taxing your pool’s circulation system, which may require expensive repairs. 

You should now take steps to balance things out after determining that the pH level is too high. The pH can be lowered by using two major items: muriatic acid and sodium bisulfate, sometimes referred to as dry acid. Here is the step-by-step process for the aforementioned. 

Bisulfate of sodium

  • Read the manufacturer’s directions and, depending on your preliminary tests, measure the appropriate quantity. Some advise adding 3/4 of what is advised in order to make corrections simpler.
  • Sodium bisulfate is typically sold as a powder. On windy days, avoid using it to prevent backlash against your skin and clothing.
  • To add the chemical, crouch down as close to the water as you can, preferably downwind if it’s windy. To make it easier to disseminate the powder around the pool, apply it to the location of the water return jet.
  • After ten to fifteen minutes, the powder ought to dissolve by itself.
  • Be sure to complete your test within 24 hours, but wait at least six hours before retesting. 

Muriatic acid 

  • Because muriatic acid has a strong corrosive effect, wear safety equipment like gloves and goggles.
  • Read the directions once more and adjust the amount as necessary.
  • Muriatic acid can be added to your pool in one of two ways. The first step is to shut off the pump before slowly pouring a stream into the deep end. Turn the pump back on after letting the acid collect at the pool’s bottom before circulating it.
  • The second approach entails pouring it over the return jets and allowing the pump to operate.
  • After six hours, retest the water, but don’t wait more than twenty-four hours.
  • All is well now that the equilibrium has been restored.

How much muriatic acid can you add to a pool at one time?

You must accurately measure the pH and total alkalinity of your pool before adding anything. 

Although test strips are fairly accurate, digital test kits are much more so. No matter what the reading, it’s advisable to add no more than a half gallon of muriatic acid at a time when decreasing the alkalinity of your pool. Plan to periodically retest your water during this process.

First, you need to know how many gallons of water your pool can hold using a pool calculator. You should be able to calculate how much acid to add using the label on your muriatic acid. If it doesn’t, though, you can enter your numbers into an online calculator. 

Try to lower your pH to just slightly below the ideal range. Your alkalinity should return to normal with this amount of muriatic acid. A 10,000 gallon tank’s alkalinity will typically decrease by 10 ppm with 20 ounces of acid. If, however, you add muriatic acid and your pH falls too low, what happens? If necessary, you can operate your pump to aerate your pool and gradually raise the pH levels.

If necessary, don’t forget that you may always add extra muriatic acid. Thus, add muriatic acid in increments of no more than 1/2 gallon at a time and start gently.

Can you add too much muriatic acid to a pool?

Adding excessive chemicals to a pool is inevitable and has been experienced by almost all amateur pool owners. So it is not a new thing.

Your pool requires about a quarter gallon of muriatic acid to bring the pH level to a neutral state, especially when it is high. The usage instructions always come with the label of muriatic acid. If you add more than the amount your pool requires, the water gets acidic. 

If you add too much muriatic acid, you’ll need to raise the pH, or drain some of the water, refill it, and rebalance it. To avoid adding excess chemicals, it is recommended that you always test the current level of the property you want to increase and add the chemicals slowly while testing.

What happens if I add too much acid to my pool?

As crucial as chlorine is to maintaining the cleanliness and safety of your pool’s water is muriatic acid. In order to maintain the pH levels in the ideal range for your chlorine sanitizer to function, it is also an essential chemical. 

For this reason, it’s crucial to add the proper quantity of muriatic acid to your pool. 

The pH levels in your pool water might drop dangerously low and acidic. When too much muriatic acid is used, it causes rashes and eye discomfort in swimmers. Low pH levels can also corrode metals in your pool, including ladders, handrails, fasteners, and other crucial pieces of equipment.

How do you neutralize muriatic acid?

Changing the pH level and using chemicals back and forth can be inconvenient and expensive, so you shouldn’t add too much muriatic acid in the first place. Moving slowly and carefully is recommended.

If you add too much muriatic acid and the pH level drops below the ideal range, you might need to add sodium carbonate or soda ash to bring the pH level back up. 

To do the stress-free method of eliminating excess chemicals from a pool. You can just drain half of the water and refill it. Then test and balance again.

How long does it take for muriatic acid to work in a pool?

Hydrochloric acid concentrations in muriatic acids can range from 28 to 35 percent. 

Coughing, hoarseness, irritation, and ulceration of the respiratory tract can all be results of acute inhalation exposure.

It is recommended that you wait two hours after using this product—as with the majority of pool treatment chemicals—before swimming.

Should pump be on when adding muriatic acid to pool?

There are different opinions on whether or not you should keep your pump running while you add muriatic acid to your pool water. 

When you add muriatic acid, you should turn off your pump because it will move the chemicals around and add oxygen, which can help the acid lower the pH. 

It could be more challenging to precisely target your ideal pH given this quick movement. 

Muriatic acid is a very strong chemical that can slowly erode your pool equipment when not added properly or circulated in the right format.

The final decision is yours, so weigh the advantages and disadvantages of each course of action.

How long should you run the pool pump after adding acid? 

Muriatic acid can cause a hot patch of acid to form in the water, which might potentially cause your skin to burn or become irritated.

It is advised to keep your pump running for at least 20 minutes after adding the muriatic acid. Once more, double check that your pump is set to “circulate” in order to aid in the muriatic acid mixing. As a result, your pool’s surfaces won’t be harmed by the acid.

Some pool owners elect to turn off their pumps at this time to allow the acid to concentrate and more effectively alter their alkalinity levels. Pooling is the method in question.

But keep in mind that if you let muriatic acid sit, it will eat away at your pool’s flooring because it is so caustic. In order to stop the acid from causing harm, you must regularly brush the pool floor. The water should now be circulated, so we advise turning on your pump.

Is muriatic acid safe for vinyl pools?

Vinyl pool liners are essential for homeowners with swimming pools in their backyards to maintain their pools’ aesthetic appeal year-round. 

Hydrochloric (muriatic) acid should not be used to modify pH since it will chemically destroy the shape of the liners. Since a substantial amount of the acid is consumed throughout the procedure, only use hydrochloric(muriatic)acid for complete alkalinity.

Residents rely on strong, cleanable, printed flexible vinyl to shield the internal pool surface from natural and artificial influences. This surface is exposed to several risks, including sunlight, temperature changes, chemicals, and irresponsible cleaning.

The most frequent reasons for damage to vinyl pool liners are premature pattern wear from abrasive cleaning instruments and bleaching from an unbalanced chemical composition.
