what sand do you use for pool filter

For those residential pool owners who rely on a sand filter system for their pools, the type of sand you use can make a big difference in the quality of your pool water.

In this article, we'll explore the different types of sand that can be used in your pool filter and what benefits each one can provide.

Why is The Type of Sand Important for Your Pool Filter System?

The sand in your pool filter system serves as a mechanical purifying agent. The filter works by gravity – Dirty water is pumped through a tank filled with sand. As the water passes through the sand, debris like dirt and leaves get stuck in the sand, leaving clean water to exit from the system.

Different Types of Sand for Your Pool Filter

1. Silica Sand

Silica sand is the most common type of sand that is used in a pool filter. It is made up of small particles of quartz and is popular among pool owners because of its affordable price and its ability to filter out impurities from the water while allowing water to pass through.

2. Zeolite Sand

Zeolite sand is another type of sand used for pool filters, and it is known as an eco-friendly alternative to traditional silica sand. Zeolite is a natural mineral that can filter out a broader range of particles, including ammonia, without reducing water flow. Zeolite can absorb foul odors and even remove unwanted heavy metals from the pool water. The only downside to using zeolite sand is its high cost compared to silica sand.

3. Glass Sand

Glass sand is an excellent alternative for those who want to invest in a more sustainable option for their pool filter. It is made from recycled glass and has become increasingly popular due to its environmentally friendly benefits. Apart from that, the biggest advantage of glass media is its enhanced clarity when compared to traditional silica sand. Glass sand can retain its clarity for longer due to its hardness and ability to reduce bacteria growth in your pool.

4. Pea Gravel Sand

Pea gravel sand is the most common type of sand used for swimming pool filters with older filter systems. This sand type is inexpensive, and it is known for its excellent ability to trap larger debris like leaves and twigs. Its size can also affect the water flow which may lead to faster wear and tear on your pool filter pump.

5. Garnet Sand

Garnet sand is a type of sand that is more expensive than traditional silica sand due to its unique filtering properties. Garnet sand has sharp edges and can trap smaller debris, making it ideal for homes surrounded by trees and vegetation. The biggest downfall of using garnet sand is the fact that it can increase the wear and tear on your pool motor and filter system due to its angular edges.

Conclusion

When deciding on what type of sand to use in your pool filter system, it is essential to consider factors such as ease of access, price, and effectiveness. Selecting the right sand for your system ensures that your pool stays clean and clear all the time. If you’re unsure about which sand is the best fit for your pool, you should consult with a pool service expert.
