I've been a pool owner for a few years now and can share a bit about what monthly swimming pool maintenance service typically includes. Generally, regular pool maintenance is crucial to keep the water safe and the pool in good condition. It can range from basic tasks to more comprehensive services.
The standard services usually include testing and balancing the water chemistry. This is super important to keep the water safe for swimming and to protect your pool equipment from corrosion or scaling. They'll usually adjust the chlorine, pH, and alkalinity levels, and sometimes calcium and stabilizer levels, depending on your pool type and usage.
