No, we don’t need to put chemicals into the pool water because the water is constantly flowing into and out of each pool, allowing a complete turn-over of all the water in the pool approximately every 2 hours. Chemicals are added to swimming pools because the same water stays inside the pool structure in a more stagnant state. In addition to the constantly moving water through each pool, every pool on the resort is drained and power-washed with an approved pool cleaning solution approximately 3 times every week.
