As summer ends, pool owners are seeking efficient ways to maintain water quality during autumn and winter. Traditional maintenance often relies on continuous chlorine and anti-algae treatments, which can be expensive and lead to chemical saturation.

Alternative approaches focus on water conservation and cost reduction through proper winterization techniques, such as covering the pool and monitoring water parameters. These methods aim to prevent the need to drain and refill pools in the spring, which is especially important in drought-prone areas. Carlos Lecea, manager of Ecoytec, notes that proactive maintenance helps prevent algae, stains, and scale buildup while allowing for the detection of equipment issues before they require major repairs.
