We clean five to seven pools per day on a cleaning schedule. Each pool is closed, power washed with an approved pool cleaning solution, and refilled to ensure cleanliness and to remove mineral buildup. ​Our Blue Lagoon swimming pool is cleaned every Tuesday night after closing and it remains closed until it is completely cleaned and refilled Wednesday afternoon. In addition to our own cleaning schedule, the water is constantly circulating in and out of each pool, allowing a complete turn-over of all the water in the pool approximately every 2 hours.
