How Do You Add Sand to a Pool Filter?

If you're looking to keep your pool crystal clear this summer, then maintaining a proper pool filter is crucial. But what happens when the sand in your pool filter needs replacing? In this article, we will guide you through the process of adding sand to your pool filter so that you can get back to enjoying your pristine swimming pool.

1. Determine the Amount of Sand Needed

Before purchasing sand for your pool filter, you'll need to know how much sand is required. The amount of sand needed depends on the size of your pool filter, so be sure to check the manufacturer's instructions or manual to determine the correct amount. Typically, pool filters require between 50 and 300 pounds of sand.

2. Purchase the Right Sand

Once you know how much sand is required, it's time to purchase the right type of sand. You should avoid using any type of sand that contains limestone or silica, as these can potentially cause damage to your pool filter or your pool itself. Instead, it's recommended to use specifically designed pool filter sand, which is available at most pool supply stores.

3. Prepare the Filter Tank

Before adding new sand, you'll need to remove the old sand and prepare the filter tank. Begin by first turning off the pool pump and closing any input and output valves. Then, remove the filter head and thoroughly clean out the filter tank. Check for any cracks or damage to both the tank and the laterals, and replace any damaged components as necessary.

4. Add the New Sand

Once the tank is prepared, you can begin adding the new sand. Carefully pour the sand into the tank, being sure not to damage the laterals as you add more sand. A small amount of water can be used to help settle the sand in place. It's important to not overfill the filter tank, as this can cause damage to the laterals and reduce the effectiveness of the filter.

5. Reassemble the Filter

Once you've added the appropriate amount of sand, it's time to reassemble the filter. Replace the filter head, tighten all clamps, and reconnect any input and output valves. Then, turn the pool pump back on and let it run for at least two minutes to help distribute the sand throughout the filter.


Maintaining a clean and safe swimming pool requires a functional pool filter, and regularly adding new sand is a crucial part of this process. By following these simple steps, you can ensure that your pool filter is always in top shape, and that your pool is always crystal clear and safe for you and your family to enjoy.
