Can I Use Baking Soda To Raise The Ph

How to raise ph to your swimming pool

Yes you can. But there are a couple of drawbacks.

  • Baking soda is only about half as efficient at raising pH.
  • Baking soda not only raises the pH, it also raises the total alkalinity. What that means in practice is that you should only use baking soda to raise pH when the total alkalinity is significantly below its desired range of 80-120 ppm. If the total alkalinity is close to or within the 80-120 ppm range, the danger is that baking soda will over-raise the total alkalinity: and then you will suddenly be two chemical levels out of whack instead of just one.

pH is the term used to refer to the degree of activity of an acid or base in the water. It is the most important chemical factor to be maintained in swimming pools. pH is measured on a scale from O to 14 with 7 being neutral. Pool water pH is best when kept in the range of 7.2 to 7.8.

A value of 7 to 14 is considered basic with 14 being the greatest base activity. Another word for basic is alkaline however, this is not to be confused with total alkalinity. pH and total alkalinity are not the same but can be influenced by each other.

A pH value between 0 and 7 is considered acidic with 0 being the greatest acid activity and getting weaker as it approaches a value of 7. When pH remains below 7.2, the water is considered to be corrosive. This means etching of plaster and metals in equipment such as heat exchangers will result. In addition, it is more difficult to keep chlorine in the pool because while more effective as a sanitizer at the low pH, chlorine is also much less stable resulting in the consumption of larger quantities of chlorine than would be used at normal pH levels.

Is Borax Slime Safe

Borax Slime is not safe because it is a mineral that happens during lake bed evaporation. It poses many health risks such as skin irritation, toxicity, hormonal imbalance, low sperm count, and eye irritation. To be on the safer side, avoid prolonged skin contact with borax slime, ingestion, and eye contact.

Low Ph Is Bad For The Pool

In addition to being bad for swimmers, a low pH is bad for your pool.

Over time, the water corrodes metal surfaces and pool components such as ladders, railings, screws, pool light fixtures, as well as metal surfaces in your pump, filter system, and heater.

And its not just metal surfaces. Acidic water causes etching and deterioration of plaster, grout, stone, concrete, and tiling.

It will also cause vinyl-lined pool surfaces to become brittle thus leaving them prone to tearing or cracking.

All these dissolved minerals are held in solution in your pool water. Or rather, theyre held in solution right up to the point when the water reaches saturation point. They then fall out of solution and stain your pool surfaces.

Also, the presence of dissolved metals particularly iron, copper, and manganese can lead to cloudy pool water.

Finally, if the pH of your pool water drops much below 7, the amount of available chlorine is greatly reduced thereby leaving your pool prone to bacteria and algae.

What Happens If Alkalinity Is High And Ph Is Low

In this case you always need to adjust the total alkalinity first and pH second. Use a chemical to lower the alkalinity and wait a day for the water to recirculate and mix. Test again and if the alkalinity is ok, add a pH increaser to raise the pH slowly to the correct level. Its important to only increase the pH in small increments, allow the pool water to recirculate and keeping testing.

When the pH level in a swimming pool is low, it means the water is too acidic. A pool with a pH below 7 can exhibit long-term problems relating to acidity such as etching of the plaster and grout used in the construction of the pool, corrosion of pipe fittings and other metal equipment and rapid deterioration of pump O-rings and seals, reveals PoolCalculator.com. An acidic pool also loses chlorine content faster, increasing operating costs. Because the pH of people’s eyes is around 7.2, pools with lower pH will frequently cause stinging eyes and dry, itchy skin for swimmers.

After two days and two nights of keeping a close watch over the process, I took the reading in the morning. Total alkalinity in my example read 101 ppmânot bad at all. The pH was stable at 7.4. Remember that even if the natural aeration process is not complete, pH levels will not likely rise above the recommended levels because the alkalinity is within range and no pH increaser was used in this process.

What Happens If Ph Is Too Low In Pool

How to raise your swimming pool ph

Acidic water is mildly corrosive and over time can damage metal fittings, plastic, grout and the pool surfaces. This includes your filtration system, pipes, valves, ladders, railings and pool cleaning equipment.

If your pool is lined with marble plaster you may get etching and pitting into the plaster that leads to black spots that are very difficult to remove. The plaster releases minerals into the water upsetting the water balance causing more problems.

Pools lined with fibreglass or vinyl-lined are not safe either. A low pH will eventually cause vinyl and plastic to become brittle, crack and tear. My fathers pool was fibreglass lined over concrete and old plaster. The fibreglass eventually become brittle and cracked allowing water to run behind the fibreglass lifting it from the concrete. When we emptied the pool I was able to tear large sheets of fibreglass off the sides and the fibreglass coating over the shallow end was floating on the concrete.

However, the main issue with low pH is that it will render chlorine ineffective against sanitizing your pool water. The chemical properties of chlorine only work in water with a fairly neutral pH. Adding extra chlorine or even shocking the pool wont solve the problem. This will leave your pool exposed to algae and bacteria making the pool unsafe for swimming.

Summary Of Key Points

  • Total alkalinity should only be lowered when it causes a significant rise in pH levels, or when it causes calcium scaling through CSI.
  • To lower pH and total alkalinity, use a strong acid such as muriatic acid, sulfuric acid, or sodium bisulfate, all of which lower both pH and TA, but at different rates.
  • You need to use an accurate water test kit that can give you correct readings. If possible, find software that can help you get exact amounts of dry acid to add into the water.
  • This process may take longer than anticipated, depending on how high pH or total alkalinity is and how low you need to bring them down before the aeration process begins. However, you can always use an air compressor or any other aerator to accelerate the process.
  • If you have achieved the ideal reading for total alkalinity but the pH is scaling up because the process of aeration has not yet ceased, you can use borate to keep the pH stable. The recommended level for pH is around 7.4 or 7.6.

How To Raise Your Pools Ph Level With The Right Chemicals

For balanced pool water, keep the pH between pH of 7.4-7.6. And there are two different chemicals you can use to raise the pH in your pool:

  • Baking Soda aka sodium bicarbonate .
  • Soda Ash aka sodium carbonate .

Note: Before you add any chemicals to your pool, make sure you know exactly how much water your pool holds so you add the correct amount of chemicals to raise your pH and other levels.

If you decide to use baking soda, just note that this chemical will also increase your alkalinity level. So if both your pH and alkalinity are low, this is the right chemical to use to raise each one.

How To Raise Ph In Pool Water

Your pool water test has just indicated the pH is way below 7.2 and you need to increase it back into the normal range of 7.2 to 7.8. How to raise the pH level in pool water is one of the most common issues encountered by pool owners so lets find out how to fix it.

Your swimming pool water is now more acidic than normal so it needs adjustment to be more alkaline by raising the pH. Adding sodium carbonate or sodium bicarbonate will increase pH but you need to be careful with total alkalinity when adjusting pH.

The Two Ways In Which Chlorine Works

How do I raise or lower the pH and Alkalinity in my Pool ...

Disinfection of water by killing bacteria and algae that cause waterborne diseases. Bacteria in the pool can cause diarrhea to swimmers, ear infections, and skin infections. Chlorine is oxygenated and helps neutralize dirt and debris that enter swimmers water and the surrounding area.

Maintaining the proper pH is essential, as it can affect chlorines effectiveness and eventually lead to unhygienic swimming conditions. Besides, it is also vital for the swimmers safety the ideal pH for a pool matches the mucous membranes and the human eye pH.

Unbalanced pH can cause itching and irritation of the eyes and skin. Therefore, a pH balance is essential for the health, safety, and comfort of a swimmer. Besides, its also necessary for the longevity of the facility.

Highly acidic water will corrode and lead to the formation of pumps, stairs, and trampolines. Lastly, an imbalance in the levels will also decrease the liner and will require frequent replacement.

Measure The Amount Of Soda Ash You Need

Make sure to follow the manufacturers instructions here but the general rule of thumb is that 6 oz. of soda ash will raise the pH of a 10,000-gallon pool by 0.2 points.

So to get from a pH of 6.8 to the minimum of 7.2 for a 20,000-gallon pool, you would need to add 24 oz. of soda ash. Do the math for your own pool to get the exact amount you need.

Check Total Alkalinity And Make Appropriate Adjustments

Total alkalinity is the sum of all basic materials in the water. Low total alkalinity can cause significant and random fluctuations in pH levels. If you are still having trouble with low pH readings after adding the appropriate amount of soda ash, check your total alkalinity.

Sodium Bicarbonate is similar to soda ash and is used in swimming pools to raise the total alkalinity . Add 1.4 pounds of sodium bicarbonate per 10,000 gallons of water and allow the pool to circulate before testing again. Use our total alkalinity calculator to figure out the exact amount.

Why Ph Balance Is Important

Maintaining the correct pH balance not only keeps your swimming pool sparkling clean but also helps preserve your pool finishs aesthetic appeal by preventing it from getting stained. pH balance is also essential to ensuring the longevity of your pool and its components.

Pools need to have a pH level of between 7.2 and 7.8. Pool water with pH levels that are low is acidic. This kind of water is corrosive and can lead to pumps and other equipment breaking down. Basically, everything that acidic water touches gets worn away, including accessories, plumbing, and other parts of the pool system.

Unbalanced pH levels can also wear down pool liners and ladders, causing them to become brittle and crack. Improper pH levels can even strip the copper right out of heat exchangers.

How to use Borax to Raise the pH in your Pool – How much Borax to Add

Sometimes the pH level goes lower than needed. If you were learning how to lower the pH level of your pool and it accidentally went too low, its time to bring it back into balance.

As for what causes low pH in a pool, that varies:

  • Leaves and pine needles may give you a lower pH reading. This includes the leaves on the pool cover.
  • A heavy rainfall, especially in a city, can lower the pH. Rain is slightly acidic and will lower the alkalinity.
  • Many people lounged in the water. Body oils and sweat may mean a low pH for your pool.
  • You used dry or muriatic acid to lower pH. It may have been too much or there couldve been other factors at play. Sometimes its a challenge to get the pH just right.

Although a low pool pH is uncommon, you can still balance it out. The pool water is too acidic now. That means you balance it with alkaline substances. Raise pool pH with borax, soda ash or aerate the water. Washing soda and sodium carbonate are other names for soda ash.

To use soda ash to raise pool pH, follow these steps:

  • Follow the directions on the package to learn how much washing soda to use.
  • Run the pool pump and filter.
  • Sprinkle the washing soda evenly across the whole pool.
  • Wait an hour for the soda ash to distribute throughout the water.
  • Test the water and proceed accordingly.

Follow these steps to raise pool pH with boric acid:

Work Out The Amount Of Chemicals You Need

To work this out you will need to know the approximate volume of water in your pool. You can read this post to find out how to calculate the volume of water.

If the volume is 10,000 gallons, and you need to raise the pH by 0.4, then you will need to add around 12 oz of soda ash or 3-4 pounds of baking soda.

I suggest that you always add in stages add some, wait a few hours and retest. Add more if necessary.

Bonus: Factors That Lower Ph

For the most part, pool pH will rise over time, so there are not too many cases where a pool’s pH remains low, or continues to lower over time. That’s why we have devoted an entire article to rising pH, and a mere bonus segment within it for lower pH. In a cementitious pool , pH will almost always rise. This segment is really more for fiberglass and vinyl liner pools.

Some reasons for pool pH being reduced or staying low include using acidic chlorine like trichlor and getting a lot of rain. Rainwater tends to be acidic, and it can be even more acidic the closer you are to a major city. Another thing: rainwater contains no calcium carbonate, meaning it’s not only acidic but super aggressive on the LSI. Other things that can lower pH in a pool are leaves and pine needles. This is an underestimated factor, especially during the offseason.

Climates that get a lot of rain or snow in the winter time, combined with leaves and pine needles on a mesh cover? Yep, that pH is going down in the short term, probably making the water low on the LSI, so it has to correct itself. This leads us into entirely different conversations about types of calcium dusting in pools that occur during the winter, as well as other issues like pool crystals and calcium formations. Fortunately, we have already written about those topics.

Chemicals that lower pH

To lower pH, you must increase dissolved CO2. There are two ways to do this.

What Causes Pool Water To Become Low Ph

As outlined above, low pH levels in your pool water can create manifold problems from maintenance issues like eroded fixtures through to irritated skin and eyes.

The majority of cases of low pH water are caused by overuse of the pool, improperly balanced chemicals, or heavy rain.

Beyond this, body fluids and perfumes dissolving into the pool can also lower the pH levels of the water. If you have recently had lots of people gathered for a pool party, this could easily trigger lowered pH levels.

Sometimes, incorrectly managing pH levels can bring about problems. As with all aspects of pool maintenance, theres a degree of trial and error involved. This is all part of the fun until you start experiencing health problems or corroded pool equipment. Armed with the knowledge from todays guide, you can now take action if required.
