How to balance your hot tub's pH and Alkalinity is an easy method.
The pH level in your hot tub can be stable with total alkalinity.It is a pH buffer.
The ideal range for alkalinity in your spa or hot tub is between 80 and 120 parts per million.Problems with your water chemistry will be caused by anything outside that range.
We will talk about why alkalinity goes up, why it is important to keep an eye on it, and how to lower it in your hot tub.
The water has a level of total alkalinity that is tied to the water's pH level.If the pH level goes over 7.6, it becomes basic.The hot tub water will be increased as well.
Pollution in the water is one of the factors that contributes to rising pH and alkalinity.This can be anything from backyard leaves and debris, to body oils, sunblock, and anything else that may be on a bather's body prior to entering the tub.
High alkalinity can be the result of shocking, a process that kills off everything in the water with a mass dose of chlorine.The chlorine-based shock is highly alkaline.
Simply refilling the tub after a drain can cause a TA increase.If the water source you use leans to the alkaline side of the scale, you will end up with highTA in the tub.
Everything is in moderation.It's the same rule when it comes to water alkalinity.If the TA level gets too high in your tub, here is what will happen.
There is no fix for high chemical levels.You can use acid to bring it down to an ideal level.
Always wear protective eyewear, gloves and never add acid to the water when using these methods.
It is easy to add a dry acid to your hot tub.You need to store dry acid in a way that it doesn't get wet.
Handling hydrochloric acid should be done with care as it can burn skin, cause permanent eye damage, and cause fumes to burn nose and lung lining.
This is the most common way to reduce alkalinity in the hot tub, as it can kill mold and remove calcium deposits.
You may notice that the pH level has gone down as well.There are a few ways to bring the pH back to normal.
Raising the TA with soda ash and baking soda has an unwanted side effect.Aerators can be used if you don't want to be balancing your water for hours.
Oxygen is infused into the water by aerating it.The carbonic acid is removed and the pH level is raised at the same time.
If you want to introduce oxygen into the water, you can buy aeration devices that attach to your tub's return jets.Due to the hot tub's design, the jets are bubbling at the surface.Simply running the jets for an extended period of time can aerate the water.
