What Sand to Use in Pool Filter?

If you have a swimming pool, it is essential to know what type of sand to use in your pool filter. The right kind of sand can help keep your pool clean and clear while also prolonging the lifespan of your equipment. In this article, we'll go over various types of sand used in pool filters and which one is best for you.

Understanding Pool Filtration Systems

Before we dive into the different types of sand, let's first understand the filtration systems used in pool maintenance. Pool filtration systems involve three types: sand, cartridge, and diatomaceous earth (DE). Among the three, sand filtration is the most common and the least expensive.

If your pool is fitted with a sand filter, it aids in removing debris and contaminants from the water. Sand filters are a robust and straightforward filtration method that works by pushing water through a layer of sand. This method traps the debris, dirt, and foreign substances, leaving only clean water that is safe for swimming.

Types of Sand for Pool Filters

1. Silica Sand

Silica sand is the most commonly used sand in pool filter systems. It is mined naturally, durable, and can last up to three years before it needs replacing. Silica sand is also clean and uniform in size, making it an ideal option for effective filtration.

2. Zeolite Sand

Zeolite sand is another sand variety used in pool filters. Unlike silica sand, which filters down to 30 microns, zeolite sand can filter down to 5 microns. This fine filtration is what sets Zeolite sand apart from Silica sand. It is also eco-friendly and can reduce the amount of chlorine required in the pool.

3. Crushed Glass Sand

Crushed glass sand is a newer alternative to traditional pool filter sand. It is made from recycled glass and can last up to six years before it needs replacing due to its durability. Crushed glass sand is also environmentally friendly and eliminates the need for waste disposal in landfills.

4. River Rock Sand

River rock sand is an alternative option for those who want to upgrade from traditional sand. It is made from smooth rounded stones and provides a uniform filtration that doesn't allow any passage of debris, dirt or impurities. River rock can last up to 10 years and becomes more efficient in filtration over time.

5. Mason Sand

Mason sand is a fine, light-colored sand that is perfect for pool filtration. The sand has smooth edges making it easy and gentle on pool equipment. It is also chemical-free, making it a safe option for people and the environment around the pool.

Conclusion

Choosing the right sand for your pool filter system is essential in prolonging the lifespan of your equipment and maintaining clean and clear pool water. Silica sand is the most common and least expensive but gives very little filtration compared to Zeolite sand and crushed glass sand. River rock sand is long-lasting and becomes more efficient in filtering over time, while Mason sand is safe and gentle on pool equipment. With this knowledge, you can make an informed decision on which sand type is best for your swimming pool.
