There are two main chemicals typically used to decrease pH in hot tubs, muriatic acid and dry acid (also known as sodium bisulfate). Although they are designed to do the same thing, pay attention to which chemical you are using, because how you add the chemical differs.
Why can’t I get my pH down in my hot tub?
In order to lower pH effectively, hot tub owners must be consistent in adding pH minus to their hot tubs. A product that is used to lower pH is sodium bisulfate. Sodium bisulfate is solid dry crystals which is a dry acid.
How do I adjust the pH in my hot tub?
Add 1 tablespoon of baking soda to the hot tub for every 100 gallons of water it holds. For example, add 4 tablespoons of baking soda to a hot tub that holds 400 gallons of water. Turn on the hot tub jets and allow the water to circulate the baking soda for two to four hours. Retest the pH level of the water.
Can I add vinegar to hot tub to lower pH?
Lower the pH of the water by measuring out four cups of vinegar and pouring it directly into the water. You can use either white household vinegar or apple cider vinegar.
Will baking soda lower pH in hot tub?
Baking soda can be quite helpful to homeowners who have hot tubs, as it can assist them in keeping the pH level of the water in the proper zone. … Baking soda can raise the alkalinity of the water and bring your pH back up to an appropriate level.
How do I bring my pH down?
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.
Will Shocking hot tub lower pH?
Oxidizers work best in a low pH environment, and the efficacy of your spa shock is twice as great at a pH of 7.5 than it is at a pH of 8.0. Check to be sure that your pH is not too high before shocking. The second most important thing is to remove your spa cover, spa blanket and spa users before shocking the hot tub.
Does vinegar lower pH?
Other benefits of vinegar

What household items lower pH in pools?
There are two main products for lowering the pH. These are sodium bisulfate (also known as dry acid) and muriatic acid.
How do I lower the pH in my pool naturally?
You can lower the pH in your pool naturally by directing the downspouts from your house into the pool. If a pool becomes too full due to backwash it dumps water. Since rain is about 5.6 pH it is going to bring down the pH of the water naturally. The problem that you will have with rainwater is its low alkalinity.
Does baking soda increase pH?
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.
Can too much bromine hot tub hurt you?
When they are too high in a hot tub this can be uncomfortable for hot tub owners to sit in. High bromine/chlorine levels can be very irritating on a person’s skin, eyes and respiratory system. It can cause red itchy skin, red itchy eyes, and effect the lungs in a negative way.
Is bromine alkaline or acidic?
Bromine tablets generally have a pH around 4, therefore, pH adjustment to the water will be necessary to maintain proper water balance. Even though bromine is effective over a wide pH range, it is important that the ANSI/APSP/ICC-11 recommended pH range of 7.2 to 7.8 and alkalinity range of 60 to 180 ppm be maintained.
Can you go in a hot tub if the pH is high?
Having pH levels that are higher than 7.8 or lower than 7.2 can cause problems for your and you hot tub. High pH is a common cause of calcium and scale build up at your hot tub water line and cloudy or dull water. It also causes bathers to often experience itchy skin and burning eyes.
Does high pH cause hot tub foam?
A Bad Chemical Balance Can Cause Hot Tub Foam
Water with a pH greater than 7.8 parts per million has too much pH, while hot tub water with alkalinity higher than 120 pm is too alkaline. Either problem can lead to cloudiness.
Can you shock a hot tub too much?
The honest truth is that every hot tub owner has accidentally over-shocked their hot tub at least once. It happens from time to time and it’s not the end of the world. Try to keep it to a minimum, though, as it can damage your hot tub and actually harm your body, too.

How quickly does pH reducer work?
The dry acid will dissolve on its own after a 5-10 minutes, so there should be little to no need to spread the powder around in the water by hand. Wait at least six hours for the chemical to mix before retesting, but try to wait no longer than 24 hour to test after adding the last dose of dry acid.
Will adding chlorine lower pH?
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).
Can I put vinegar in my hot tub?
You can use vinegar or any acetic acid to clean your hot tub, but we recommend our pH Down for best results. Vinegar is an all-purpose cleaner. … It makes perfect sense, then, that vinegar is also effective for cleaning your hot tub.

If you want to raise your pH and alkalinity together, use soda ash (sodium carbonate). If your goal is to raise alkalinity only, use baking soda (sodium bicarbonate).
Does white vinegar lower pH in water?
Diluting vinegar with water increases its pH value, because vinegar is an acid and water has a higher pH level. However, adding water to vinegar can never turn vinegar into an alkaline, because water has a neutral pH.
