How do I maintain the water in my hot tub?

Filter system

The filter pump has a natural filter system where the water is pumped past filter medium and the coarse dirt remains behind. The UV filter lowers the level of micro-organisms and kills 90% of the bacteria. This keeps the water clean for much longer, up to 2-3 months. A simple and sustainable solution to save water. You can read everything about maintaining the filter system here.

Clean the tub and flush the stove

Use a mild detergent, such as detergent or all-purpose cleaner, and rinse thoroughly. Don't forget the stove: you can flush it with a garden hose via the penetrations on the inside of the tub. Remove the heater stop so that water and dirt can flow away.

Measure the values of the water

Before adding a maintenance product to the water, the pH and TA values must be in balance. Once you have filled the hot tub, it is important to measure these values. If you add maintenance products if the values are incorrect, the maintenance product will not work. Measure the values every time you fill the hot tub. This is because the values in water can change all the time.

You can measure the values with test strips. The pH and TA values are two separate values and must be adjusted separately.

pH value:

The pH value indicates the acidity of the water. It is ideal if it is between 7.2 and 7.6. If the value is too higher or lower, you must adjust it with an raiser/lower.

TA value:

The TA value stands for the total alkalinity (total amount of alkaline substances) of the water and refers to the water's capacity to neutralize the acids and stabilize the TA value. It is best if the TA value is between 80 and 120 ppm (milligrams per liter). If the value is higher or lower, you must adjust it with an raiser/lower.

If both values have been adjusted and are good, you can add a maintenance product such as Aquaclean or chlorine.

Tip: Always start by checking the TA value. Only with the right TA does your pH remain stable. Then you set the pH value good in, so that chlorine and other agents work optimally.

Of course, other factors are also important. Go into the hot tub clean, because cream, deo and other care products can influence and confuse the values.

The weather has an effect on your water‍

‍It's good to know that the weather also affects the water in the hot tub. For example, does the weather suddenly change from bright sunny to heavy rain? Then this is reflected in the pH value in your hot tub.
