Quick Answer: How To Lower The Alkalinity In Your Pool

The two most popular chemicals available to help you lower the total alkalinity in your swimming pool are muriatic acid and sodium bisulfate (also known as dry acid).

How do I bring my alkalinity down?

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 a pool?

One of the main reasons pool alkalinity can get too high is when you have added too much sodium bicarbonate (baking soda) when you were trying to raise it. Another factor that often causes alkalinity levels to get too high is your water source.

What happens if pool alkalinity is too high?

In addition to this, high alkalinity levels can also cause issues like red and irritated eyes, dry skin, itchy scalp, and even earaches. Besides just physical problems, high alkalinity levels can cause cloudiness in the water, circulation issues, excess wear and tear on your filters, and algae and calcium build up.

Will pool alkalinity lower on its own?

Now it’s important to note that high alkalinity levels will naturally decrease over time on their own. But high total alkalinity can precipitate other issues, like high pH and ineffective chlorine, which can lead to algae. So it’s often worth addressing high alkalinity levels before they can cause more trouble.

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.

Does baking soda lower alkalinity?

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.

Does shock lower alkalinity?

Another cause for high alkalinity can be when you shock the pool. While this is performed to quickly rid the pool of pollutants, chlorine-based pool shock is highly alkaline, and can raise the water’s total alkalinity level in the process.

Will vinegar lower alkalinity in a pool?

Mostly no. The amount of impurities and sugars in vinegar compared to Muriatic Acid or Sodium Bisulfate could cause staining and provide unintended fuel for bacteria and other microorganisms, though the vinegar’s acidity could successfully lower pool water pH levels.

Will high alkalinity make your pool cloudy?

Pool water with a high total alkalinity (TA) is often associated with cloudiness. This is because it can cause an imbalance in the pH levels and lead to calcium scaling. Typically if your TA is higher than 200 ppm, you’re at risk of a cloudy pool and just like imbalanced pH levels, your chlorine will be less effective.

Does muriatic acid lower alkalinity?

One gallon of muriatic acid will lower the alkalinity about 50 parts per million per 15,000 gallons of existing balanced pool water. By diluting the muriatic acid with balanced pool water, you lessen the risk of damaging your eyes, lungs or skin, or your pool deck or interior finish.

What do I do if my pool is 8.2 pH?

To bring down pH, use a made-for-pools chemical additive called pH reducer (or pH minus). The main active ingredients in pH reducers are either muriatic acid or sodium bisulfate (also called dry acid).

How do you fix high alkalinity in a pool?

The first step is to lower pH by adding muriatic acid. Lowering pH will make your pool water more acidic and neutralize the alkaline materials in your pool. You should aim to lower your pH to a range of 7.0 to 7.2. The second step is to aerate your pool or hot tub to break up the remaining alkaline materials.

Will Clorox pH down lower alkalinity?

Clorox Pool&Spa pH Down safely lowers pH level of pool water. You need to maintain your pool water pH levels and total alkalinity for the comfort and safety of users and for other pool products to work properly. Use test strips or test kit to measure ph. The ideal pH for pool water is between 7.2 And 7.6.

Can I pour muriatic acid in my pool?

Easy does it Most experts agree that muriatic acid is the best option to lower the pH and alkalinity levels of your pool water. You can also use it to clean tiles, remove stains, dissolve calcium deposits, and kill any mold and algae leftover in your pool at the end of the year.

What causes alkalinity to drop in a pool?

There is a perfectly natural reason for this: evaporation and agitation of your water leads to a drop in the total alkalinity. and high heat levels will increase the water evaporation and degassing phenomena. For all these reasons, the total alkalinity in your swimming pool will fall continually during the season.

Does pH Decreaser lower alkalinity?

The easiest way to lower alkalinity in your hot tub is by adding a pH Decreaser (sodium bisulfate).

What should I fix first pH or alkalinity?

Check Total Alkalinity (TA) first, then adjust for proper pH range. Proper TA will buffer pH, that is, it will help to prevent pH fluctuations. Use fresh, high quality test strips. Excessively high bromine or chlorine levels can result in false pH and TA readings.
