Is the water in Macao swimming pool seawater or fresh water?

Most of the water in Macao swimming pool is fresh water. Macao is located on the continental shelf and has no coastline directly connected with the ocean. Therefore, the water in swimming pools is usually provided through the fresh water supply system, rather than directly using seawater. Some resorts and luxury hotels in Macao have seawater swimming pools, and the water in them may be treated and filtered seawater, but this is rare. Please note that the details may vary from pool to pool. It is recommended to consult relevant places before use to ensure accurate answers.
