NSW has one of the highest concentrations of residential swimming pools in the country, particularly across the Eastern Suburbs, Northern Beaches, Inner West, North Shore, and Sutherland Shire. The swimming season stretches from October through April, and the warm conditions are ideal for algae bloom, chlorine depletion, and water chemistry going wrong fast. A pool that looks fine on Monday can be green and unsafe by the weekend without proper maintenance.
Professional pool cleaning goes well beyond scooping leaves and throwing in a chlorine tablet. It involves testing and balancing the water chemistry — pH, chlorine, alkalinity, stabiliser, and calcium hardness — which interact in complex ways. Incorrect chemistry doesn't just turn your pool green; it damages the pool surface, corrodes equipment, irritates swimmers' eyes and skin, and creates conditions where harmful bacteria and pathogens thrive.
Most NSW pools benefit from weekly or fortnightly professional servicing during swimming season. The cost per visit ($60–$120) is far cheaper than the remediation when chemistry goes wrong — an algae outbreak requiring shock treatment, brushing, and days of filtration can cost $300–$500 to fix. Regular professional maintenance also extends the life of pool equipment by keeping chemistry in range and catching minor issues before they become expensive failures.
