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.
What do I do if my pH is low in my spa?
If the pH is still low, continue to add more product and test periodically until the water is in range. During this time, do not add any other chemicals to the water or try to adjust other levels. Patience is always the best course of action when balancing your spa water.
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.
Can I use baking soda to raise pH in Spa?
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 raise the pH in my spa naturally?
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.
How do I raise the pH and alkalinity in my hot tub?
There are two ways to increase your hot tub’s alkalinity level: sodium bicarbonate (baking soda) or any type of alkalinity increaser product. If you choose to purchase an alkalinity increaser product be sure the product is made from sodium bicarbonate, which is the main substance used to raise pH.
How do I raise the pH in my hot tub without raising alkalinity?
Use Aeration to Raise Pool pH Looking to raise pH without affecting Total Alkalinity? You can sometimes raise the pH through aerating the pool water. Yep, just add air! It’s the same reason hot tubs and spas often suffer from high pH issues.
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.
Does shock raise pH?
When you shock a pool, you test and adjust the pH level for a reason. With that said, if you shock a pool outside of the 7.2 to 7.4 pH range, not only will you waste a significant amount of the chlorine used, you will also end up with cloudy water.
Why does hot tub pH keep dropping?
There are a variety of causes of lower pH levels, it may be as a result of: The water in your area naturally being more acidic. The water becoming imbalanced through the use of sanitisers or other hot tub chemicals.
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).
How much baking soda does it take to raise pH?
As per standard, 1.25 pounds of baking soda is enough to raise the PH level of a 10,000-gallon pool by 10ppm, so to achieve a 100ppm alkalinity, you would need 12.5 pounds of baking soda for a 100,000 gallon of pool 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.
What causes pH to rise in hottub?
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.
What does shocking a hot tub mean?
Shocking a spa means applying an ample dose of chlorine (sodium dichlor) or non-chlorine shock (potassium monopersulfate or MPS). One purpose of this treatment is to break-down organic waste contaminants which cause odor and cloudy water. It then becomes hypobromous acid in water, a good sanitizer.
Is Spa up just baking soda?
Baking soda and TA increaser are the same in chemical name only, the actual percentage of the stuff is a much higher concentration in the pool and spa chems.
Does low pH cause foam in a hot tub?
Foam will appear if the pH balance of your hot tub water is off. Water with low calcium or too much pH or alkaline can lead to cloudy water. Regular Use. If you use your hot tub frequently, you yourself could be causing foam to appear.
How much pH should I add to my hot tub?
Add one (1) ounce of pH/Alkalinity Down per 100 gallons of spa water (500 gal. = 5 oz.) and run the jets to mix and dissolve for several minutes.
