Hot tub water maintenance

The optimal effect of disinfectants - depends on the correct pH value; which in turn depends on the TA value. With the right TA value, the pH value can remain stable and with the right pH value, disinfectants can perform well. The pH value indicates the acidity of the water. Ideally, it should be between 7.2 and 7.6.

If the pH drops below this level, the added disinfectant is quickly consumed. If the pH value is too high, the effectiveness of the agent is significantly reduced and skin and eye irritations can occur. The TA value represents the total alkalinity (total amount of Alkaline substances) of the water and refers to the ability of the water to neutralize acids and stabilize the TA value. It is best if the TA value is between 80 and 120 ppm (milligrams per liter).

It's also good to know that the weather also affects the water in the hot tub. If the weather suddenly changes from bright sunny weather to heavy rain, the pH level in your hot tub will reflect this. If you add Always Blue to the water, for example, this will ensure that the weather changes have little to no effect on the water.
