Calcium lumps in a pool are calcium deposits that form when a pool's water parameters are not in the normal range. They can float around on the surface of the pool water, making it look and feel dirty. The most common causes of calcium lumps in pools are calcium hardness above 1,000 ppm, alkalinity over 120, and a pH over 7.8. Keeping your pool’s calcium levels, alkalinity, and pH levels within the normal, safe ranges is the best way to prevent calcium lumps and other problems, including damage to the pool surface.

At noon, when the sun is at its highest point, sunlight can naturally increase the temperature of a pool by 0.7 degrees each hour, but this can depend on other external factors. For example, evaporation caused by the sun will cause a pool to lose up to 5 degrees for every 1/2 inch of water evaporated. Using a water heater will produce more reliable results.

Pool maintenance costs an average of $230 per service, with prices ranging from $50 to $750 per service, depending on several factors. The type of service will usually be the most significant cost factor, as opening and closing a pool takes a few hours and can total $400 or more, while regular cleanings could cost under $100. The size of your pool and the type of pool—above-ground, in-ground, saltwater—can also affect the price of maintenance.

Pool chemical levels should include a pH between 7.4 and 7.6, alkalinity between 80 to 120 ppm, and chlorine from 1 to 3 ppm. The size and type of your pool determine additional chemical levels, such as stabilizers and pool shock, but you can get to know these numbers using our pool maintenance 101 guide.
