Borax acts as an effective pH buffer and helps prevent algae growth in swimming pools. Plus, it will leave your water looking sparkly and feeling soft.
Use 20 Mule Team Borax which is quality borate to raise the pH without affecting the TA and see if pH will be stable. If you get too much borate, drain and refill 1/3 to 1/4 of your Pool Water and use pH increaser instead of borate. You can lower both pH and TA using Muriatic acid If they get off the balance.
Adding 76 oz or 4.75 lbs of boric acid per 10,000 gallons of water will provide 10 ppm of borate. Boric acid is a weak acid and has a pH of 3.8-4.8. It will not lower pool water pH by much. Most of the time the pH drop is only about 0.2 for a 50 ppm dose.
If your pool has good circulation, then 30 minutes would be more than adequate to be safe.
In the right amounts, borax will do a great job of increasing the pH of an unbalanced pool. Not only that, but it will do so without raising the total alkalinity in the process. Since borax is not a carbonate compound, its effects on the water's alkalinity will be negligible.
Borax can also help to keep water clear and inhibit the growth of algae by stabilizing pH in the proper range.
Benefits of Using Borax
While they do raise pH levels, they also raise the total alkalinity of the water.
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). Reducers are readily available at pool supply stores, home improvement centers and online.
If you are using one of the boric acid products or your own borax pool treatment, you can test the levels of borates in your pool by using the AquaChek Borate Test Kit. Test your borate levels in your pool monthly, or as needed, to maintain the residual of 30-50 ppm of borates in the water.
Baking soda can work wonders in a pool. Baking soda can: Help to clear cloudy water and restore the sparkle. Spot-treat algae.
Vinegar contains acetic acid which makes it a great disinfectant. It is also acidic in nature hence removes dirt, grease and mineral deposits. If used in the right amount, its acidic nature also plays a role in lowering the pH of pool water.
Cloudy Pool Water: Causes, Treatment, and Preventive Measures. Cloudy or milky swimming pool water is caused by seven main issues: improper levels of chlorine, imbalanced pH and alkalinity, very high calcium hardness (CH) levels, faulty or clogged filter, early stages of algae, ammonia, and debris.
Borate serves as a buffer for the pool. This means algae is a lot less likely to form in the water. Algae is annoying for every pool owner, so this is good news. This is due to the most important fact regarding borate; borate helps stabilize the pH of your water (See relationship between Chlorine and pH).
Chlorine. Chlorine is a slimy-feeling material when it gets wet. If you have chlorine dust or residue on your fingers and then touch the pool water, the pool water will feel slimy. Avoid this by wearing gloves when dealing with all pool chemicals, and never add water to chlorine; only add chlorine to the water.
Boric acid and sodium borates are commonly used as a pH buffer in swimming pools and spas, meaning they help increase the capacity of the water to resist changes in pH. However, they have other uses as well: Boric acid and sodium borates can inhibit algae growth and reduce corrosion.
Borax is the sodium tetraborate decahydrate (Na2B4O7 · 10H2O) that, when dissolved in water, is hydrolyzed to boric acid and OH− anions, yielding a pH of about 9.13.
But the BBB method was started by PoolSolutions and the term was coined by CarlD. It stands for Bleach, Baking Soda and Borax. The only other chemical you will need on a regular basis is Muriatic Acid which I will cover later in this article.
The most common reason for a consistently high pH level in pools is the use of liquid chlorine or a saltwater system as the primary sanitizer. Sodium hydroxide is produced, which has a pH of around 13. New pool plaster or pebble finishes will also raise pH in pools for about a year after installation.
Can you swim in a pool with high pH? Definitely, but know that chlorine in the water may not be as effective as it normally would and you may be exposing yourself to harmful microorganisms. Besides, the water can also turn cloudy and your pool sides may scale due to alkaline water.
Here are common causes of an alkaline pool: Algae can raise the pH. Adding strong liquid chlorine, calcium or lithium hypochlorite chlorine may raise it. Suddenly heating the water, whether from a pool heater or a string of sunny days, could up the pH.
It takes nine hours to fill a 5,000-gallon pool at 540 gallons per hour.
Borax is a powdery white substance, also known as sodium borate, sodium tetraborate, or disodium tetraborate. It's widely used as a household cleaner and a booster for laundry detergent. It's a combination of boron, sodium, and oxygen.
As for the Foundation product, neither borax nor EDTA will remove phosphates. Typically, lanthanum chloride is used to reduce phosphates as lanthanum phosphate is insoluble.
Borates provide both chemical and aesthetic benefits to pools as well as potentially increasing the longevity of pool plaster and other equipment. Unlike most other water additives, borates are permanent and do not degrade or evaporate from pool water with time.
