Comprehensive Guide About Hot Tub Alkalinity

What is the definition of total alkalinity?

Total alkalinity, often known as total alkalinity (TA), is the capacity of water to offset acidic variations in pH. The amount of acid that can be applied to a body of water prior to experiencing a substantial change in pH is determined.

Instead of greenish water with goopy growth around the edges of the shell, it helps evaluate which treatment is most effective in keeping your spa water clean and clear. It’s also a major offender if you check your water and notice that it smells strange.

Understanding the roles of alkalinity is crucial for a number of reasons.

If you’re interested in learning more about hot tub water chemistry, it’s helpful to know the following terms:

Alkalinity is the ability of water to withstand acidic conditions.

Acidity is defined by the presence of a chemical solution or water combined with a chemical.

The pH of your hot tub water indicates the amount of acid or base present.

If any of these factors are out of balance, a variety of side effects can occur, including rapid pH changes, skin irritation or dryness, water that has a green tint, a funky smell that is similar to mold, and, if the problem is left untreated for an extended period of time, corrosion of your hot tub shell and other components, as well as the possibility of system failure.

Be aware that anything that comes into contact with or interacts with your hot tub water may modify the pH levels, which might cause the chemical composition to change. Consider anything from body oils and lotions to detergents (including those needed to wash your swimwear), shampoos, fragrances, hair products, and any other product that we humans prefer to use on a regular basis. Other factors to consider include the quality of your local water supply and the use of too many spa chemicals (which is not unusual). Ultimately, you should strive to maintain the pH levels in your water as balanced as possible.

Test the alkalinity of your hot tub with these simple steps:

Use a testing strip to determine the alkalinity level of your spa water to have a better understanding of the situation.

After dipping the testing strip in the water and shaking off any excess water, compare the color of the strip to the bottle chart on the back of the kit to see whether the results are correct. Your next line of action will be determined by the color of your strip at the conclusion of it.

We propose putting on a low-pressure jet to assist in circulating the chemicals into the water, and then leaving the lid open enough to allow the water to breathe beyond that point.

Before re-testing your spa water after adding ANY chemicals, it’s a good idea to let the water circulate for a few hours (or overnight) to ensure that your levels are correct.

At any given moment, the pH of your hot tub water should be between 80 and 120 parts per million (ppm).

How can I lessen the alkalinity of my hot tub?

If your alkalinity is very high, it is possible that you have hard water in your location. Because of the high alkalinity levels, chlorine or bromine-based disinfectants may be rendered ineffective in certain cases. It’s possible that your spa’s disinfection isn’t working properly if you have mineral buildup in the water or if the water is hazy. Other problems include skin and eye discomfort, algae growth, and scales on the shell’s surface.

How to Increase the Alkalinity of Your Hot Tub

Using Total Alkalinity Increaser in accordance with the guidelines on the bottle will raise your alkalinity to an acceptable level. This should raise the alkalinity of your water to a more neutral range.

If tests and treatments fail to resolve the problem, it may be necessary to do a pH test to determine how acidic or basic your water is to determine the cause. Although PH levels and alkalinity are not exactly the same, the testing procedure is quite similar, and the conclusion will be the same if the water is treated appropriately and with the appropriate chemicals.

A shock treatment may be required in certain circumstances, or it may be essential to empty and refill your hot tub with new water, after which you may begin adding your chemical treatments from the beginning once again.

If you decide to go in one of the two directions (treating your present water or starting over with new water), we’ll be here to assist you in figuring things out.
