For example, a heavily-used pool with lots of debris may require sand changes more frequently, while a smaller pool with less use may be able to go longer between sand changes.

It can be tough to tell when it’s time to change the sand in your pool filter, but there are a few signs to watch for. One is decreased water pressure from your filter. If the pressure gauge on your filter reads 8-10 psi higher than when the sand was last changed, it’s time to replace the sand. Another sign that it’s time to change the sand is if your pool water is not as clean and clear as usual, despite regular chemical treatments and cleaning.

3. Remove the filter head and drain the filter tank.

4. Use a wet/dry vacuum to remove the old sand from the filter tank.

What Type of Sand Should You Use in Your Pool Filter?

There are several types of sand that can be used in pool filters, but the most common is silica sand. Silica sand is affordable, readily available, and effective at removing debris from pool water. Some pool owners use alternative filter media, such as glass or zeolite, which may offer certain advantages over traditional sand. It’s important to consult your pool manufacturer’s recommendations to ensure you are using the appropriate filter media for your pool filter.


Changing the sand in your pool filter may seem like a daunting task, but it’s an important aspect of pool maintenance that will keep your pool clean and safe to swim in.
