Take Final Water Test 48 Hours Later
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.
How To Lower Alkalinity In A Pool
If the alkalinity of the water is too high, i.e. more than 120 ppm, its an easy fix to lower the alkalinity of the water.
First, make sure the water pump is on and take a current pH measurement.
Add one quart of muriatic acid or 2 pounds of dry acid at a time around the perimeter of the pool.
Let the acid mix in the water for about an hour, then test the water again. Maintain a water pH of about 7 and keep adding pool acid in small increments until the correct alkalinity level is reached.
Once the alkalinity level is correct, allow the pH to climb naturally by circulating the water.
Only add soda ash to raise the pH if the pH stops climbing after 1 week.
What Happens If Ph Is Too Low In The Pool
The pools overall health could suffer if proper care isnt taken because bacterial growth rates increase with lowered pH. It may not take long before you have a green or black slimy surface as well as an unpleasant odor coming from your pool.
It also can affect swimmers experience like itchy eyes and irritated skin. The pool pH should be in the range 7.2 to 7.6 which is generally a similar pH to that of human tears. If the pH is lower than this then that is a major factor in making eyes sore after opening your eyes under water. When that happens people assume it is because of too much chlorine but that isnt usually correct. It is more likely incorrect pH.

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.
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.

What Does Baking Soda Do For A Pool
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. Many commercial pool products for raising alkalinity utilize baking soda as their main active ingredient. You can maintain your pool for a fraction of the cost by going straight to the source and using pure baking soda in your pool.
What Happens In A Low Ph Swimming Pool
On the other hand, swimming pool water with low pH levels is acidic this you can actually feel the difference as you take a dip and swim. If you swim in an acidic pool, expect skin irritation and burning eyes the moment you open them underwater.
Just like in an alkaline pool, chlorine and other chemicals may not be effective in pool water with low pH. Metal parts of your pool can also corrode, and vinyl linings may wrinkle if the water is too acidic.

Test The Ph Using A Digital Ph Meter
A digital pH meter is a little more expensive but its worth the investment. A digital pH meter requires you to put your probe in water and press one button to get instant results of your pools pH levels.
To use a digital pH meter, you have to calibrate the device with some liquid or buffer solution. The calibration instructions will be included in the package for your specific model of digital pH meter.
After calibration is complete, just dip your probe into a clean sample of pool water and wait until it gets an accurate reading on the screen!
How To Raise Alkalinity In Pool Without Raising Ph
When your pool waters alkalinity is lower than the recommended range, one of the best ways to increase it is by using an alkalinity increaser. This product can be purchased from your local pool supply store and boasts the ability to lower total alkalinity and buffer pH. However, most are unaware of the fact that an alkalinity increaser is just sodium bicarbonate.
Sodium bicarbonate is more commonly known as baking soda. Yes, simple baking soda found in your kitchen can be used to raise your pools alkalinity. In fact, youll likely be able to save quite a bit of money when you use baking soda over alkalinity increaser. With baking soda, you can enjoy all of the same benefits of packaged alkalinity increaser at a reduced price.

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.
What Causes Low Pool Alkalinity
The following points are to be considered as culprits for pool alkalinity
- Use of dry acid or muriatic acid. These chemicals, although useful in treating swimming pool water, are notorious for reducing pH concentration in water. A way of fixing this is by applying only a prescribed dose of the chemical in case there is a need to lower your pools pH. Then you can test your pools alkalinity level after 6 hours.
- It probably rained hard. Rainwater might be low in alkaline levels, and when it rains hard, your pool may become flooded, and this will affect the average alkalinity of your pool.
- If you drain or backwash your pool, adding freshwater with a low alkalinity level is bound to deplete the overall pH of your pool.

Is It Safe To Swim In High Or Low Ph Or Alkalinity
Maybe yes, maybe no. Your pool water pH and alkalinity can affect disinfection by chlorine. Chlorine is very slow to react at high pH levels, and can be over 50% inactive at pH levels over 8.2. However, even with high pH a pool could still be sanitary with good levels of free chlorine, and clear water from effective filtration.
How To Balance Ph And Total Alkalinity In A Swimming Pool
Balancing pH and Total Alkalinity might seem difficult if you’re doing it for the first time. However, this is something you can fix within a few hours if you have the right chemicals and follow the steps included in this article.
The most common problem is high pH and TA levels in pool or spa water. If you maintain the correct levels of pH and TA in your swimming pool, having low pH and alkalinity levels is not common and can only be caused when any form of a strong acid like muriatic acid or sulfuric acid is added into the pool or spa water.
Before we go further, I guess you would want to know the causes of high pH and alkalinity in your water so that you won’t fight high levels of pH and TA next time.

Maintaining a balanced swimming pool pH is a vital part of swimming pool maintenance. Not only does the proper pH protect your metal fittings and the walls of your pool, but the right pH range is also what makes swimming in the water pleasant instead of an itchy, burning trial. The correct range for a swimming pool is a pH of 7.4 to 7.8. If you are testing your pool and the pH registers as too low, try the techniques below to raise your pH.
1. Check Your Reagents
The first thing to check when your test indicates a low pH is whether your test reagents are still good. Reagents should be replaced every year and should never be mixed between test kits. If your kit is old, try getting a new one and testing again.
2. Add Soda Ash
If your pH is still low, try adding sodium carbonate, commonly called soda ash. Never add more than two lbs of soda ash per 10,000 gallons of water in your pool in any single treatment. Distribute the soda ash over the whole of the pool surface, starting in the deep end. Make sure that the pump is circulating to distribute the water and then wait an hour or so before testing again. If the pH is still too low after an hour, you can add more soda ash.
3. Check Your Total Alkalinity and Add Baking Soda
Other Common Problems With Total Alkalinity And Ph Levels
Alternatively, you can naturally aerate your pool while the pump is on 24/7 to raise the level of pH up between 7.6 and 7.8 or higher, which might take a couple of days, and then lower both the TA and pH using muriatic acid slowly and carefully while watching on the pH levels not to go very down: Repeat the process until you get the required levels for both total alkalinity and pH.

How To Raise Ph Levels In Your Pool
Maybe you have noticed something off with your pool water, or perhaps it was just time to test the water. You run the test, and the pH is low. You retake it to be sure and again, it is low. What steps can you take to raise the pH level and get it back in balance?
There are a number of things that you can try to correct the issue and raise the pH level in the pool. Before you go to the trouble of adding products and additional testing, double-check your reagents. Your test strips should be replaced at least once per year, if there is a chance that these are out of date, buy a new test kit and test again.
Aerate The Pool Water
Sometimes, adding alkalines to your water still doesnt raise the levels sufficiently.
In this case, its time to aerate the water thoroughly. This is a lengthy process that could stretch out over a few days. One method of achieving it is to activate water features so that jets hit the surface of the water. An alternative method is to go all-in and add some aeration pipes.
If you follow this guidance, low pH levels in your pool should be no further cause for concern.
What causes this situation to happen in the first place, though?

How To Increase Ph In The Pool
There are any number of commercial chemical products that you can use to raise the pH of your pool. Usually they have brand names that involve the word pH Increaser, Up, or Raise.
We recommend this pH increaser here.
Whatever their trade name, all these products are based on sodium carbonate otherwise known as soda ash. Be aware, though: sodium carbonate isnt the same thing as sodium bicarbonate, AKA baking soda.
Yes, you can use baking soda to raise the pH in pool, but its not ideal. See below.
- Make sure that the pump and filter system is running.
- Test your water in order to determine the current pH and, therefore, how much you need to raise the pH back to the desired 7.4-7.6 range.WORD of WARNING: pool test kits and testing strips typically only measure down to a pH of 6.8. So, if your pool waters pH is showing a reading 6.8, the actual reading may be even lower. What you need to do, first, is to bring the pH back up into the measurable range, and then fine tune from there. We recommend these Water Testing Strips and Liquid Testing Kit here.
- Calculate how much sodium carbonate you need to add. As a general rule 175 grams of sodium carbonate will raise the pH of an average backyard pool of 32 m2, or approximately 42,000 litres of water, by 0.1.
Grams of Sodium Carbonate Required to Raise pH to 7.4-7.6
|340 grams||8.0 grams|
- Retest the water for both pH and total alkalinity after 6-12 hours .
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 lbs of baking soda.
I suggest that you always add in stages add some, wait a few hours and retest. Add more if necessary.
