How do I bring the alkalinity down in my pool?
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.
What causes high alkalinity in pool?
Pool pH is Always High
The most common reason for a consistently high pH level in pools is using liquid chlorine, or a saltwater system as the primary sanitizer. Sodium hydroxide is produced, with a pH of around 13. New pool plaster or pebble finishes will also raise pH in pools, for about a year.
Will pool alkalinity lower on its own?
The range you’re shooting for with alkalinity is somewhere between 100 parts per million (ppm) and 150 ppm, with 125 ppm being ideal. One of the most important things to remember about high alkalinity is, if you can afford to wait, it will decrease over time on its own. … That’s what alkalinity does.
How do you lower alkalinity without lowering pH?
If you wish to lower the pH without also reducing the Total Alkalinity, simply pour the dose of muriatic acid about the pool. “ This would all be wonderful if it was only accurate. Still, just like the mythological “Chlorine Lock,” folkloric tales within the swimming pool industry do persist.
What should be adjusted first alkalinity or pH?
You should test alkalinity first because it will buffer pH. Your reading should be in the range of 80 to 120 parts per million (ppm). If you need to increase the alkalinity, add an increaser. To lower it, you’ll add a sodium bisulfate.
Will vinegar lower alkalinity in a pool?
You can purchase products from a pool supply store to regulate the pH, but if you do not have these chemicals on hand or if you prefer a more natural approach, adding vinegar to your spa can safely lower the pH.
Is high alkalinity in a pool bad?
If your pool water is too alkaline, it can cause scaling on your pool’s surface and plumbing equipment, and can cloud the pool water. In addition, both high acidity and high alkalinity will alter the effectiveness of your chlorine, which will clearly disrupt your pool’s disinfecting processes.
How do I balance the pH and alkalinity in my pool?
You may need to make repeated adjustments of lowering alkalinity and then raising pH – until both come into proper range. If your alkalinity is balanced and you pH still needs adjustment, you will either add pH increaser, which is chemically known as sodium carbonate or soda ash, or pH reducer.
Does pool shock raise alkalinity?
Typically goes hand in hand with pH. If the alkalinity reading is low, then most likely the pH reading is low and visa versa. Typically chlorine shock contains alkaline which will help raise the alkaline level. On the flip side of that, chlorine tablets which contain cyanuric acid tends to lower the alkalinity.
How do I bring my pH down?
Products to help lower pH levels
- Sodium bisulfate.
- Muriatic acid.
- Test ph and alkalinity.
- Measure your chemicals.
- Add the chemical.

- Re-test and repeat as needed.
- Test pH and alkalinity.
How long after adding muriatic acid can you swim?
Some people will tell you that it’s safe to swim just 30 minutes after adding muriatic acid to your pool water. But we recommend playing it safe by waiting three to four hours and testing your water before swimming in your pool.
How much acid is needed to lower alkalinity in pool?
The main rule to keep in mind is that it takes 25.6 oz. of full-strength muriatic acid (31.45 percent hydrochloric acid) to lower the total alkalinity by 10 ppm in 10,000 gallons. The problem: If one adds enough acid to lower the total alkalinity all at once, the pH can get very low.
What household items lower pH in pools?
Baking Soda to Raise pH and Alkalinity in Pools
Most people know that chlorine is an important chemical in keeping pool water safe for swimming. But adding too much chlorine can lower your pool’s pH as well as its total alkalinity.
Will baking soda lower chlorine level in pool?
Chlorine works most efficiently in water with a neutral pH level between 7.4-7.6. … To raise your pH levels, it can be as simple as adding seven to nine pounds of baking soda to your pool water.
