Which pool type is most likely to require unique filtration needs?

Special pools are designed for specific uses that can include varying depths, unique shapes, or specialized water features, such as those found in therapeutic or competitive settings. These specific purposes can lead to distinct water quality and filtration requirements. For instance, a therapeutic pool may need a filtration system that can maintain higher sanitation levels, while a competitive swimming pool might have requirements for water clarity and temperature control that are more stringent than those typical for public pools.

In addition, special features such as slides, fountains, or underwater lights can create different circulation demands, necessitating unique filtration methods or technologies to effectively manage water quality. In contrast, while public recreational pools and residential pools do have set filtration standards, their needs tend to be more standardized given their common designs and user expectations. Hot tubs, while they do require special considerations such as temperature and sanitization due to the smaller volume of water and higher bather loads, do not generally represent the vast range of filtration demands that special pools might.
