The nozzles of swim spa jacuzzi tubs usually need to be used for a long time and frequently. As the use time increases, the strength of the nozzles in terms of water pressure, air flow, etc. gradually increases, which may cause wear and aging of the internal parts of the nozzles.

The water quality adjustment of the whirlpool massage bathtub is relatively complex, because the particularity of its water flow and temperature system requires that the water quality be kept within a certain balance range. For example, the pH value, chlorine content, hardness and total alkalinity of the water need to be kept within a certain standard range.

Generally speaking, the pump power range for small outdoor hot tubs is between 0.5 and 2 horsepower. The specific choice of pump power needs to be comprehensively considered based on the size of the bathtub, the number of massage nozzles, the intensity of the water flow, etc.

For swim spa jacuzzi, it is recommended to add chlorine or bromine at least once a week when the water temperature is appropriate. Generally, the concentration of chlorine should be maintained at 1 to 3 ppm (parts per million), and the concentration of bromine should be maintained at 3 to 5 ppm.

Microorganisms and organic matter in the biofilm are gradually released into the water, causing the water quality to become turbid. If you find that the water in your spa jacuzzi bathtub is no longer clear and the filtration system is unable to effectively remove particles from the water, this may be a sign of biofilm formation.

In many whirlpool hot tubs and spa equipment, "PR" generally refers to "Priming Mode", which is "drainage mode" or "starting mode". This is a special mode that the whirlpool hot tub automatically enters after the initial power-on or restart.

Grounding is one of the basic safety requirements for any electrical equipment. For outdoor whirlpool bathtubs, especially when used outdoors, it is particularly important to ensure that they have a good grounding system.

When the chlorine content in a spa jacuzzi bathtub is too high, the first thing that is affected is the water quality itself. Excessive chlorine content may cause the water quality to become turbid and form chloride precipitation.

As a relatively fast-acting disinfectant, chlorine needs to be added frequently when used, while bromine has a relatively low maintenance frequency. Especially in terms of maintenance frequency and the application of automated equipment, bromine can provide outdoor spa hot tub users with an easier management experience.

The so-called jelly-like substance in the massage hot tub filter is usually called "biofilm". This sticky substance is a microbial aggregate, a gel-like structure formed by bacteria, fungi, algae and other microorganisms.

Regularly cleaning the interior of the outdoor garden hot tub, including removing grease, dirt and sediment, can effectively prevent water pollution. When cleaning, focus on cleaning the bathtub's nozzle, pipe system, filter and other parts to ensure that every detail is kept clean.

If air lock occurs, users will notice that the water flow of the outdoor whirlpool bathtub is significantly weakened or even stops completely. Even if the pump is started, the water flow is still very weak and cannot achieve the normal massage effect.
