The most straightforward approach to filling an in-ground swimming pool is to connect a garden hose from your exterior tap. However, this is not the best idea if there's water scarcity or restricted rationing. If so, you'll want to make alternate arrangements, like getting a water delivery service to fill your pool.

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.

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.

If you put too much baking soda in your pool, your alkalinity will rise. That means you’ll need to take steps to lower your alkalinity. You can either add more water (which will require more chemicals because they’ll be diluted), wait for the alkalinity to lower naturally, or use a chemical like muriatic acid to lower it.
