When the pH level in a swim spa tub is too high, the most direct impact is decreased water quality stability. A high pH level alters the chemical reaction environment in the water, making certain substances more prone to sedimentation or particle formation.

The water in spa equipment typically needs to maintain a stable chemical balance, such as pH, alkalinity, and disinfectant concentration. Rainwater has different chemical properties, so it may affect these parameters after entering the water.

Provided proper maintenance, short-term idle periods generally do not adversely affect the structure of the swim spa tub. The key is to complete the necessary preparatory work before idleness, such as cleaning, draining, and disconnecting the power.

When the swim spa tub activates its jet system or strong water flow, the water is rapidly agitated, drawing in a large amount of air. If substances in the water stabilize these bubbles, they won't burst immediately but will instead gather at the surface, forming foam.

If the swim spa tub has a leak, the water level change often has the following characteristics: • The water level drops significantly faster than normal evaporation • The water level continues to drop even when the tub is turned off • The water level may stop dropping after reaching a certain height (corresponding to the leak point height)

Swim spa tubs are not "only" placed on concrete floors, but they must be placed on floors that meet the requirements for load-bearing capacity and stability. Concrete floors are simply the easiest way to meet these requirements.
