If your PH and/or Alkalinity is high, you need to add a PH Minus to reduce these levels. Do this gradually. Add the correct dose of PH Reducer, then run the jets and re-test in an hour or so and see if you need to reduce further. PH Minus is the sole chemical used to reduce PH and Total Alkalinity in your hot tub.
What happens if pH is too low in hot tub?
A low pH level means your hot tub water is acidic, which can not only cause corrosion of surfaces and equipment, it can also reduce your ability to control Total Alkalinity and cause an uncomfortable experience for your family and guests, as acidic water will sting eyes and remove the natural oils on skin, leaving it.
What causes high pH in hot tub?
Hot tubs in particular generate a lot of bubbles and tend to have higher temperatures. This combination creates a gas called carbon dioxide very quickly. Carbon dioxide builds up and makes the pH go up. This is why hot tub owners, on a regular basis, need to add something to lower their pH and alkalinity.
How do I increase pH in hot tub?
To raise or lower the pH level in your hot tub, test the hot tub’s current pH level and then add the appropriate amount of FreshWater® pH/Alkalinity Up or FreshWater® pH/Alkalinity Down to the water. Repeat the process as needed until your hot tub has reached the correct pH level of between 7.2 and 7.8.
Does 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).
Is it OK to go in hot tub with high pH?
It is not safe to get into a hot tub with high pH. A pH value of 7.8 or higher is considered to be a high pH when measured with a pH strip. Water at these levels is too alkaline that it reduces the effectiveness of Chlorine, the chemical compound responsible for killing pathogens in your hot tub water.
How do you fix high 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). Reducers are readily available at pool supply stores, home improvement centers and online.
How do I lower the pH in my spa naturally?
How to Lower pH in a Hot Tub With Vinegar Test the pH of the hot tub after the water has been circulating for a few hours. Lower the pH of the water by measuring out four cups of vinegar and pouring it directly into the water.
Does chlorine raise pH in hot tub?
Hot tubs are often at a pH level of 7.2 – 7.8. Adding chlorine will increase this number slightly, but because the chemical also reacts to form hypochlorous acid, which reduces acids and makes your hot water less acidic, there’s no change unless large amounts of chlorine are added.
Is it safe to get in hot tub with low pH?
The Dangers Of Low pH Low pH poses risk to your spa and it’s water because acidic water has the potential to hinder your sanitizer’s ability to properly work. Meaning, your spa will become a breeding ground for contaminants. This is dangerous because high levels of contamination can pose health risks for hot tubbers.
Will baking soda increase pH in Spa?
As many homeowners know, the ideal pH for a hot tub or pool should be between 7.2 and 7.8. Baking soda can raise the alkalinity of the water and bring your pH back up to an appropriate level.
What happens if you put too much chlorine in a hot tub?
If theres too much chlorine it will vaporise and form gas that floats just above the surface of the water. If this vapor is inhaled it can inflame airways and exacerbate certain breathing conditions. Read more What Temperature Should My Spa Pool be at and Why?Jul 13, 2020.
Is it OK to swim in 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.
Why is pool pH always high?
Pool pH is Always High 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. If your pool has water features, such as a waterfall or fountain, these will also raise pH levels in your pool (more on that below).
How do I lower the pH in my spa without alkalinity?
To lower the pH level of your hot tub water, you can take four cups of vinegar and pour it in the water. Remember to circulate the water in the tub before you pour in the vinegar. You can either use the vinegar you have at home or use apple cider vinegar. Turn off the jets and test the water after a few hours.
