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 fix low 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.
What causes low alkalinity in hot tub?
Why You Have Low Alkalinity First, it can be caused by humans. Rain water is a common offender in lowering the alkalinity of water, as it leans on the acidic side of the pH scale. If you don’t use a hot tub cover, you may find your water out of balance after a downpour. Chlorine could also be the culprit.
How do I adjust the alkalinity in my hot tub?
Start up the hot tubs pumps. If you need to lower the alkalinity, add pH decreaser in the amounts shown on the back of the bottle. If you need to increase the alkalinity, add total alkalinity increaser in the amount shown on the back of the bottle. Let the water circulate with the pumps on for 5-10 minutes.
Is low alkalinity bad in a hot tub?
Any part made out of metal that comes into contact with water that has low total alkalinity can corrode, putting your heating elements, pipes, and heaters at risk. Calcium scaling can also occur, making it more difficult to keep surfaces clean and plumbing free of scale buildup.
Can I use baking soda instead of alkalinity up?
Baking Soda for Pools: An Easy Way to Raise pH and Alkalinity. Don’t waste money on commercial alkaline-increasing pool products when you can use baking soda to raise your pool’s pH and alkalinity instead.
Does raising pH raise alkalinity?
Raising PH Level PH Plus will increase your Alkalinity level slightly too so keep an eye on this as remember Total Alkalinity is the buffer to allow your PH to be set.
Does pH up increase alkalinity?
Adding pH Increaser can also raise Total Alkalinity, compounding the problem. Make repeated adjustments of lowering Alkalinity and then raising pH until both come into proper range, testing the water each time before adding more chemicals.
Should you raise pH or alkalinity first?
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.
How do you increase total alkalinity?
Use an alkalinity increaser like sodium bicarbonate to raise total alkalinity, or an acid to lower it. When using high-pH chlorines like salt chlorine generators, liquid chlorine or cal hypo, you will need less alkalinity, like 60-80 ppm. For low pH chlorines like Trichlor, 100-120 ppm might be a better range for you.
What should total alkalinity be in a spa?
Total alkalinity should be kept at 80–120 ppm. To raise low alkalinity and stabilize your pH, use sodium bicarbonate over a period of time.
What is pool alkalinity increaser?
In The Swim Pool Alkalinity Increaser is a fast dissolving, easy to use powder for all types of pools and spas. Proper Alkalinity and pH balance is key to maintaining healthy pool or spa water. Alkalinity helps to stabilize the pH balance in your pool.
Can you swim in a pool with low alkalinity?
Your swimming pool can come to immeasurable harm if it contains water with low alkalinity. You risk your pool walls becoming etched, delaminated, or cracked.

Why does my chlorine level keep dropping in my spa?
Swim spa and hot tub owners who are struggling to keep the chlorine levels up might have an issue with biofilm. Biofilm is caused by bacteria or microorganisms that stick themselves to a surface that is in contact with water. Resistant to chlorine, biofilm will cause the chlorine to “disappear” from your hot tub water.
How much alkalinity do I add to my hot tub?
You should aim to get the total alkalinity of your tub between the range of 80 and 120 parts per million (ppm) as anything above or below this will make balancing your pH level difficult. It’s worth noting that when trying to adjust your pH levels, it can also change the total alkalinity of the water.
How much baking soda does it take to increase alkalinity in a 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.
