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.

Generally, you should run your pool pump for eight to 12 hours a day to keep your water clean and chemical levels balanced. The ideal runtime can vary depending on your specific pump type. While running the pump as much as possible is ideal for cleanliness, it can increase electricity costs. To save money, you can run the pump strategically during non-peak hours when electricity is cheaper, which is often in the evenings or at night. The hours do not need to be consecutive.

The generator in your saltwater pool conversion kit transforms sodium chloride—the same salt as table salt—into chlorine. A process called electrolysis sends electricity through the water to interact with the chlorine ion. This ultimately creates the chlorine that keeps your pool safe and clean. The cell in your saltwater chlorine generator is the part that converts the salt into chlorine.

Pool leaks most commonly occur at joints or where different materials meet. The most frequent leak spots include:

• The Pool Skimmer: Where the plastic skimmer meets the pool's liner or shell.

• The Pool Liner: Tears can develop in vinyl liners, especially those between 5 and 20 years old. Leaks also occur around the liner's edge.

• Fittings and Accessories: Areas around return lines, the main drain, and pool lights are common culprits.

• Pool Equipment: The pump, filter, and filter housing can also leak.

While leaks in underground pipes are less common, they can be costly to fix. It's usually best to check the more common spots before investigating the plumbing system.
