can i put play sand in my pool filter

2023/11/05

When it comes to maintaining a clean and clear pool, the filter plays a crucial role. It is responsible for capturing dirt, debris, and contaminants in the water, keeping it healthy and safe for swimmers. Different types of filter media are available, and one of the most common ones is sand.


If you are wondering whether you can put play sand in your pool filter, the short answer is no. Play sand is not designed to withstand the pressure and flow rate of a pool filter system and may clog or damage it. Instead, you should use the appropriate grade of pool filter sand or other suitable filter media. In this article, we will explain why using play sand in your pool filter is not recommended and offer some alternative options.


Why You Should Not Use Play Sand in Your Pool Filter


Play sand is a type of sand that is typically used for children's play areas, sandboxes, or landscaping. It is made of crushed quartz or silica, with rounded grains that are smooth and clean. Play sand is not designed to be used in pool filters, for several reasons:


1. Play sand is too fine for most pool filter systems. The grains are typically smaller than the recommended size for pool filter sand, which is about 0.45 to 0.55 millimeters in diameter. As a result, the sand can flow through the filter too quickly, reducing its effectiveness.


2. Play sand is not graded for uniformity. The size and shape of the grains can vary, leading to voids or channels in the filter bed where water can bypass the sand and go directly to the pool. This can leave debris and contaminants in the water, making it cloudy and potentially harmful.


3. Play sand can clog the filter. Because it is finer than pool filter sand, it can easily become compacted, reducing the flow of water through the filter. This can result in backpressure, which can damage the filter and reduce its lifespan.


4. Play sand can affect the pH and alkalinity of the pool water. Since play sand is not designed for use in pools, it may contain impurities or additives that can alter the chemical balance of the water. This can lead to algae growth, corrosion of the pool equipment, or skin irritation in swimmers.


Alternative Options for Pool Filter Media


If you are looking for a suitable filter media for your pool, there are several options to choose from. Here are some of the most common ones:


1. Pool filter sand. This is the most widely used filter media for pool filters. It is made of specifically graded sand that is carefully washed and dried to remove impurities. Pool filter sand has a uniform shape and size, which allows for maximum filtration and a long lifespan.


2. Diatomaceous earth (DE). DE is a fine powder made of fossilized diatoms, a type of marine plankton. It is used as a filter media in some types of pool filters, such as DE filters. DE has a high porosity, which allows it to capture even the smallest particles and contaminants in the water.


3. Cartridge filters. Cartridge filters use a pleated fabric or paper filter element to capture debris and contaminants. They are easy to install and maintain, and they offer good filtration performance for small to medium-sized pools.


4. Zeolite. Zeolite is a natural mineral that has been shown to be effective as a filter media for pool filters. It has a high porosity and specific surface area, which allows it to filter out particles as small as 5 microns. Zeolite can also help reduce chlorine consumption and improve water clarity and quality.


5. Glass media. Glass media is a newer type of filter media made of recycled glass that has been crushed, cleaned, and graded for pool use. It has a high surface area and a unique shape that allows for maximum filtration efficiency and extended lifespan. Glass media can also reduce water consumption, backwashing, and chemical use.


Conclusion


In summary, using play sand in your pool filter is not recommended, as it can clog, damage, or affect the chemical balance of the water. Instead, you should choose a suitable filter media, such as pool filter sand, DE, cartridge filters, zeolite, or glass media, depending on your pool size, usage, and preferences. By using the right filter media and maintaining your filter regularly, you can enjoy a clean, clear, and healthy pool all season long.
