What Are The Signs Of Low Ph In Hot Tub
You are ready for some fun and frolicking, but when you remove the hot tub cover the water is foamy? Unfortunately, this is not a good thing! Foamy water is only one sign of low pH in your hot tub. Here are a few more:

Do you know the difference between pH levels and total alkalinity?
What Can I Use To Raise The Ph In My Hot Tub
There are two main ways to raise the pH level in a hot tub. The first way is to use chemicals called pH increase. Add 1 cap of the pH increaser, let the hot tub mix for a couple of hours, and test the water again. Soda ash is used as a quick solution to raise pH. The second way is to add fresh water to the spa.
I have seen that you can use baking soda to raise pH in your hot tub. But this is not the only option you have because soda ash is also available to naturally help you accomplish the same purpose.
Most hot tub users prefer soda ash because it has a higher pH value of 11.4, which exceeds that of baking soda. As a result, its effect on the pH is drastic when added to a hot tub.
Soda ash will also raise the waters total alkalinity more than baking soda, which is another reason that increases its effectiveness. However, it is essential to note that you cant raise the pH without alkalinity and vice versa.
When alkalinity is in question, it is essential to ensure that it does not go outside the range of 80 and 120ppm. Baking soda could be used where these values are close to the boundary because adding soda ash might take them higher than recommended.
Alkalinity plays a critical role in maintaining suitable pH by acting as a buffer to prevent fluctuation. Conversely, the absence of proper total alkalinity in the hot tub water causes erratic change by dropping or peaking.
Our recommended product to raise pH in hot tubs is Spa Essentials pH increaser Granules.
How To Decrease The Ph Level In Hot Tubs
Using the pH decreaser such as sodium bisulfate can lower the pH level in your hot tub. Another way that you can use for reducing the pH level is by using Muriatic acid. You should use protective gear such as gloves for resisting chemicals and safety glasses while using this chemical as it is very caustic in nature.
To be safer, it is better for you to use some alternative product other than muriatic acid which is not caustic in nature. But it is still better to wear all the safety gear.

Lowering Your Hot Tub Ph
If you have basic or alkaline water, you will need to lower your pH. Ask your pool store professional for a pH decreaser or a product with sodium bisulfate which is the main ingredient used for lowering pH.
Pay attention to the instructions on your pH decreaser. Some products require you to dilute the product before adding it. You’ll also need to circulate your spa water after adding in your decreaser to allow the product to infiltrate the body of water entirely. Be sure to also check your total alkalinity as a pH decreaser can influence your total alkalinity level.
Please make sure when you test your re-test your pH after treating your water, that you also test the total alkalinity level!
Choose Between Ph/alkalinity Down And Ph/alkalinity Up To Optimise Your Hot Tubs Ph Level
To bring up alkalinity in a spa pool, use a sodium bicarbonate-based product, like FreshWater® pH/Alkalinity Up. This is the safest and most common way to increase the pH of your spa pool. To lower alkalinity levels, use a sodium bisulfate-based product, like FreshWater® pH/Alkalinity Down.
If you want to increase alkalinity and pH in your spa pool using FreshWater® pH/Alkalinity Up, you should do it carefully – you dont want to continually bounce between a number that is too high then too low. Add 20mL for every 500L your spa pool holds, then test your pH again.

High Ph Lowers Tub Value
Now you know that having a low pH level in your hot tub could lead to disastrous results. But that doesnt mean the more basic your water is, the better. No way.
Unfortunately, a too-high pH also prevents your sanitizer from working. Same problem, same bacteria. And same health risks. Yikes.
In addition to making your hot tub water straight-up unsafe, a pH reading above 7.6 will also increase your calcium hardness, form scale, and make your water cloudy. Gross.
Add The Alkaline Increaser
After turning on the jets, add the measured alkaline increaser or baking soda to the water. Then keep the jets running for about 20 minutes.
This gives the alkaline increaser enough time to be fully dissolved and dispersed in the water. After adding the increaser, you should leave the hot tub unused for about 6 hours.

How To Raise And Lower Alkalinity In A Hot Tub
Raising and lowering the alkalinity in a hot tub is something you need to be cognisant of when owning a hot tub. There are two ways to increase your hot tub’s alkalinity level: sodium bicarbonate or any type of alkalinity increaser product.
Low total alkalinity is bad for your hot tub’s various components , as the surface of the shell can become etched, pitted, and even the protecting layer of the shell can delaminate. 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. Therefore, you need to raise the alkalinity using a product such as SpaBoss Alka-Rise.
Raising a low alkalinity hot tub isn’t the same as making it more basic or less acidic what we’re talking about is increasing the total concentration of alkaloids within the water. The most common types of alkaloids in hot tub water are carbonates, bicarbonates, hydroxides, and other minor alkaloids. These alkaline substances buffer pH in the water by neutralizing acids. In other words, total alkalinity is a measurement of the waters ability to resist change in pH. Alkalinity increasers are products designed to increase the total concentration of alkaloids in hot tub water.
Here’s how to fix alkalinity levels in a hot tub:
What Is Total Alkalinity
Total alkalinity sounds like how you might end up after a few too many drinks. But it actually means the capacity that a solution has to buffer or neutralize acids.
When we talk about water balance, total alkalinity or TA will always be your starting point. Without the right TA, you will find adjusting your hot tub pH level difficult.
The first, and most important step to a well-balanced hot tub pH, is achieving the optimal TA before adding any other chemicals.

Low Ph Has A High Risk
You never want your pH level to dip below 7.4especially far below 7.4. The lower your hot tubs pH, the more acidic it is.
Heres why thats a bad thing.
Highly acidic water will stop your sanitizer from working efficiently. That means that swimmers in your spa are less likely to be alone: a whole host of bacteria will join them. Sometimes, that bacteria can be harmful.
This scenario can be even worse than inefficient sanitizer in a swimming pool. Thats because hot tubs operate at much higher temperatures than poolswhile the average pool temperature is between 78 and 82 degrees Fahrenheit, hot tubs are somewhere between 98.6 and 104 degrees Fahrenheit. Any temperature above 85 degrees is more welcoming to bacteria. That includes their offspring, since theyre more likely to reproduce at rapid rates in a nice, comfortable, warm pool of water.
Since untreated or mistreated hot tubs are more likely to host bacteria, there are some pretty nasty strains that have already been documented. This includes pseudomonas aeruginosa, which causes hot tub folliculitis, and legionella, which causes Legionnaires Disease.
Bet youre feeling pretty ready to keep your pH maintained right about now.
Theres more: low pH can also cause corrosion on your equipment and plumbing. So keep yourself, other swimmers, and your hot tub healthy. Dont let your pH drop below 7.4.

How To Raise The Ph In Your Hot Tub
Most pH increasers contain the active ingredient sodium carbonate. You might recognize this chemical by its more common namesoda ash.
You may be thinking, that sounds an awful lot like sodium bicarbonatebaking soda. Youre right. Theyre closely related, and baking soda will also raise the pH in your hot tub. But its not nearly as effective as soda ash. So when youre considering how to raise the pH in your hot tub, choose soda ash over baking soda, and youll save yourself a lot of time and trouble.
Sodium bicarbonate is actually much better for raising TA, especially if you dont want to affect the pH level too much.
Its important to note that soda ash can also dramatically increase total alkalinity. So if your hot tub pH is low, but the total alkalinity is normal or high, sodium carbonate may increase the alkalinity beyond the recommended maximum level.
Also note that soda ash can make your hot tub water cloudy, so if you use it to lower pH levels, you may have to address a cloudy hot tub afterward.
