Author: Poolking - Swimming Pool Equipment Manufacturer

Intex pools are one of the most popular above ground pools in the market. These pools are quite easy to assemble and maintain. To keep the water clean and clear, an Intex pool filter is an essential tool. The filter removes dirt, debris, and other impurities from the water making it safe for swimming. However, one question that pool owners commonly ask is how much sand they need for their Intex pool filter. In this article, we will discuss this question and provide helpful tips for those who want to keep their Intex pool filter in optimal condition.

1. Understanding the Intex Pool Filter

Before discussing how much sand is needed for the Intex pool filter, it's crucial to understand how the filter works. The Intex pool filter uses a sand filter system, which works by passing water through a tank filled with sand. The sand captures debris and other impurities, leaving the water clean and clear. However, over time, the filter's efficiency will decrease, and the sand will become clogged with debris. It's important to replace the sand regularly to ensure optimal performance.

2. Determining the Size of the Intex Pool Filter

The first step in calculating how much sand is needed for the Intex pool filter is determining the size of the filter. Intex pool filters come in different sizes, and each size requires a different amount of sand. The size of the filter is typically measured in gallons per hour (GPH). You can find this information in the owner's manual or on the label of the filter.

3. Calculating How Much Sand is Needed

Once you know the size of your Intex pool filter, you can calculate how much sand is needed. The amount of sand required is typically presented as a weight measurement in pounds. A general rule of thumb is to use one pound of sand per gallon of water in the pool. For example, if your pool holds 5,000 gallons of water, you will need to use 5,000 pounds of sand.

However, it's important to note that the manufacturer's instructions should always be followed. Some filters may recommend using a different amount of sand based on their design and size.

4. Choosing the Right Sand

Now that you know how much sand you need, the next step is to choose the right type of sand. Intex pool filters require a specific type of sand known as pool filter sand or silica sand. This type of sand is specially designed to capture and filter debris and impurities effectively. You should avoid using regular sand as it will not perform the same way and may damage the filter system.

5. Installing the Sand

Before installing the sand, it's essential to check the filter system for any damage or leaks. Once you have confirmed that the system is in good condition, you can begin adding the sand. The sand should be poured into the top of the filter tank using a funnel. The sand should be leveled off at the top of the tank, so it is even and does not cause any blockages.

6. Maintaining the Intex Pool Filter

Now that you have installed the sand, it's important to maintain the Intex pool filter. The filter system should be backwashed regularly to remove debris and other impurities that have been trapped by the sand. The frequency of backwashing will depend on how often the pool is used and how dirty the water is.


In conclusion, choosing how much sand you need for your Intex pool filter is not a hard science. The most important things to remember are to follow the manufacturer's instructions, choose the right type of sand, and maintain the filter system regularly. By doing these simple steps, you can keep your Intex pool sparkling clean for endless hours of fun.
