Maintaining the proper chemical balance in your pool water not only keeps the water sparkling clean, it also helps protect your heater, pump, and other system components from damage, and can assist in keeping your pool finish looking like new. … The pH level of pool water is a measure of its acidity.
Why is pool pH so important?
To ensure that everyone enjoys using your pool, it is important to keep the swimming pool pH levels in balance at all times. If the pH is too high, it could cause skin irritation and corrode metal parts on the pool. If the pH is too low, it could create a situation where the chlorine in the pool isn’t as effective.
Is it better to have high or low pH in pool?
Proper pool pH is right in the middle — pool pros recommend that pH be between 7.3 and 7.6 for optimum performance and cleanest water. If the pH gets higher than 7.8, the water is becoming too alkaline. … Water with a pH that’s too high also can cause skin rashes, cloudy water and scaling on pool equipment.
What happens if pH balance is off in pool?
Low pH water will cause etching and deterioration of plaster, grout, stone, concrete and tiling. Any vinyl surfaces will also become brittle, which increases risk of cracks and tears. All of these dissolved minerals will hold in the solution of your pool water; which can result in staining and cloudy pool water.
How do I balance the pH level in my pool?
- Always take proper precautions and wear proper Personal Protective Equipment when balancing pH.
- Add soda ash if your pool’s pH level is below 7.2. Add Muriatic Acid or Sodium Bisulfate if it’s above 7.8.
- Continue to add appropriate product until your water has a pH level of 7.2-7.8 (ideally 7.4-7.6).
Is it bad to swim in a pool with high pH?
A swimming pool with a high pH is considered alkaline, which can cause issues with the pool and swimmers. … This means bacteria and other microorganisms may thrive in your pool. While you cannot see with your naked eye, bacteria in your pool water can be harmful when they enter your body.
Will chlorine increase pH?
Using liquid chlorine raises the pH of the water. Liquid chlorine does not raise pH. When added to water, liquid chlorine (which has a pH of 13) makes HOCl (hypochlorous acid – the killing form of chlorine) and NaOH (sodium hydroxide), which raises pH. … So the net effect on pH is zero (or almost zero).
Will pool pH lower on its own?
Minerals that decrease the pH build up naturally over time. If you let this happen the pH is going to go down on its own. Continue to use the test strips to check the levels and you should change the water once it gets below the recommended pH. … If a pool becomes too full due to backwash it dumps water.
Does shocking pool lower pH?
Shocking your pool is important, but if you’re using cal-hypo (calcium hypochlorite), it can raise your pool’s pH levels. Don’t stop shocking your pool, but do test all your chemistry levels consistently, especially after shocking.
Does chlorine lower pH?
High chlorine levels decrease the pH of your pool’s water, making it more acidic. The more acidic the water, the higher the likelihood of corrosion. This corrosion can affect metal piping, equipment, and the surface of your pool (tiles, liners, concrete, etc.).

Should I adjust chlorine or pH first?
Rule of thumb is to do the PH first. And do not bother to drive to pool store to spend the extra money for a PH DECREASER. Buy a plain baking soda for 50cents a pound in Walmart! Chlorine will not work fully until your PH is in the proper range.
At what pH is chlorine most effective?
The pH scale goes from 0 to 14, where pH 7 is neutral. If the pH is above 7, the water is basic; if it is below 7 the water is acid. The optimum pH for pool water is 7.4, since this is the same as the pH in human eyes and mucous membranes. A pH of 7.4 also gives good chlorine disinfection.
Why does pool pH keep rising?
Non-stabilized chlorines like calcium hypochlorite (cal hypo), sodium hypochlorite (liquid chlorine), and salt chlorine generators all tend to raise the pH of the pool. … Liquid chlorine’s reactions create byproducts of both high pH (Sodium hydroxide) and low pH (Hydrochloric acid), which neutralize each other.
Does chlorine affect pool pH?
Pool Chemicals The chemicals used to sanitize the pool also affect the pH of the water. Granulated or liquid chlorine is alkaline and, therefore, tends to raise the pH level. Bromine is more neutral and has a minimal effect on pH, while chlorine gas is acidic and lowers pH.
How do I fix low pH in my pool?
If your pool’s pH tested below 7.2, add 3-4 pounds of baking soda. If you’re new to adding pool chemicals, start by adding only one-half or three-fourths of the recommended amount. After retesting, you can always add more if the level is still low.
How do you get perfect pool water?
- Test and Adjust Total Alkalinity. …
- Test and Adjust pH. …
- Measure and Adjust Calcium Hardness. …
- Add Sanitizer to Your Water. …
- Check and Adjust Cyanuric Acid. …
- Measure Your Water’s Total Dissolved Solids. …
- Shock Your Swimming Pool.
What raises pool pH?
To raise your pool pH levels, try adding in sodium carbonate (AKA soda ash). Make sure that you don’t add any more than two pounds of soda ash per 10,000 gallons of water per treatment. When adding in the soda ash, start adding from the deep end of your pool and work your way up to the shallow end.
Does pool shock raise pH?
When you shock a pool, you test and adjust the pH level for a reason. With that said, if you shock a pool outside of the 7.2 to 7.4 pH range, not only will you waste a significant amount of the chlorine used, you will also end up with cloudy water.
Does too much chlorine make pool cloudy?
Excessive levels of pool chemicals can cause your water to become cloudy. High pH, high alkalinity, high chlorine or other sanitisers, and high calcium hardness are all common culprits.
Is 8.2 pH too high for pool?
The pH range of 7.2 to 7.8 should be considered an IDEAL range, not the minimum and maximum. Many pool service companies have been successfully maintaining the pH between 7.8 and 8.2 on tens of thousands of pools without reports of disease or algae outbreaks resulting from high pH.
Can I use vinegar to lower pH in pool?
Ordinary household vinegar could in theory be used to lower the pH of your pool. The pH of vinegar is about 2.5, which is quite acidic when compared to your pool water. Household vinegar is very weak though (when compared to a strong acid like muriatic acid), so you would need quite a bit to lower pH.
Can you swim in a pool with high pH and alkalinity?
Can You Safely Swim in a Pool With High Alkalinity? As long as you have enough chlorine in your pool (around 3ppm for total chlorine) and the pH level is balanced (between 7.4 to 7.8), then a pool with high total alkalinity is still safe to swim in.
Why did my pool turn green overnight?
Pool water turns green because of algae in the water. Algae can grow rapidly, particularly when it’s warm like Summer, which is why it can surprise you overnight. This generally comes down to an imbalance or lack of chlorine in the water.
Can you over shock a pool?
You cannot overshock a swimming pool or add too much. Adding too much shock or overshocking your pool will kill off algae. The negative of adding too much shock is it will upset the chemical balance of your pool. It’s likely to do that regardless of if you overshocked the pool or not.
Will baking soda lower pool pH?
Depending on what PH you wish to achieve, adding a little baking soda will simply not affect the PH level of your pool, thereby causing it to remain almost the same way (acidic). However, adding too much baking soda might also raise the PH level of your pool to an undesired stage (alkaline).
How long does it take to lower pH in a pool?
Question: How long do I have to wait to swim after adding muriatic acid? Answer: If it’s small pH adjustment then it is ok to swim after 1 hour of pool circulation. If a large quantity of acid is being added, wait 24 hours then re-test the pH to make sure the water is not too acidic.
How quickly does pH reducer work?
After adding pH increaser or decreaser you’ll want to wait about two to four hours, although some chemical manufacturers suggest a full turnover cycle, before retesting. The smaller the increments you need to adjust for pH, the less time you’ll need to wait for the results to become stable.
How do you know if your pool has too much chlorine?
- Sudden onset of nausea and vomiting.
- Burning sensation in throat.
- Itchy eyes.
- Difficulty or shallow breathing.
- Skin redness.
- Dull chest pain.
What happens if pool water level is too high?
If the water level is too high the debris floating next to the opening may pass by without being pulled into the skimmer. However if the water level is too low it may cause the skimmer to suck air into the system. If this happens you may run the risk of burning up your pool pumps motor.
When should you shock your pool?
