how much sand does my pool filter need

Author: Poolking - Swimming Pool Equipment Manufacturer

Sand filters are a popular and effective way to keep your pool clean and clear of debris. However, ensuring that your filter has the correct amount of sand is crucial for proper filtration. In this article, we will discuss how much sand your pool filter needs and provide you with tips to maintain your filter for optimal performance.

What is a Pool Sand Filter?

A pool sand filter is a mechanical filter that uses sand as the media to remove debris, dirt, and other contaminants from the water. It works by pumping water into the top of the filter, and the water then passes over a bed of sand. The sand traps particles within the void spaces between the grains of sand, leaving only clean water to flow out of the bottom of the filter and back into the pool.

How Much Sand Does My Pool Filter Need?

The amount of sand your pool filter needs depends on the size of your filter tank. Generally, pool filters come in two sizes: 19-inch tanks and 24-inch tanks. If you have a 19-inch tank, you will need 150 pounds of sand, whereas a 24-inch tank requires 300 pounds of sand.

When To Add More Sand

Over time, sand in your filter tank can break down and become less effective at filtering debris from your pool. If you notice that your water is cloudy or not as clean as it should be, it may be time to replace the sand in your filter. It is recommended to replace the sand every five years for optimal performance.

How To Replace Your Pool Filter Sand

Before replacing the sand in your filter, turn off your pool pump and drain the filter tank. Next, use a scoop or small shovel to remove the old sand from the tank. You can use a garden hose to rinse out any remaining sand and debris from the tank.

Once the tank is clean, add the correct amount of new pool filter sand to the tank. Use caution when adding the new sand, so you do not damage any of the internal filter components. Spread the sand evenly throughout the tank, and then reassemble the filter head and valve. Be sure to follow the manufacturer's instructions for your specific model.

Finally, run your pool pump for several minutes to allow the new sand to settle and adjust your filter's settings as needed. It is also recommended to backwash your filter for two to three minutes after replacing the sand to remove any excess particles.

Tips For Maintaining Your Pool Filter

Here are some tips to keep your pool filter working efficiently:

1. Check and clean your filter basket regularly.

2. Backwash your filter every two to three weeks, or as needed.

3. Monitor your water pressure gauge to ensure your filter is functioning correctly.

4. Keep your pool's pH levels balanced.

5. Replace your filter sand every five years.

Conclusion

Maintaining your pool filter is essential to keep your pool water clean and clear. Understanding how much sand your pool filter needs and when to replace it is crucial for optimal performance. By following these tips and regularly maintaining your pool filter, you can enjoy crystal clear water all season long.

----It is best to replace the silica sand of sand filters every 1-2 years for the following reasons:
a During backwashing, the filtration bed volume will expand upwards by 1.2 to 1.3 times. The water flow will drive the filtration layer to flow up and down, causing the filtration material particles to collide with each other. Backwash will let the small sand evacuate.
b.Some silica sands will be welded when the acid and alkali are changed due to insufficient purity;
Therefore, the longer the time, the worse the filtering effect of the sand tank. Since backwashing will consume and take away some sand, we need to replace the sand in the sand tank within the specified period.
After about 5~10days ,or when the reading of the pressure gauge on the pump side of the filter has increased by about 0.2bars since the last backwash , backwash the filter as follows:
1. Stop the pump
2.Close the valves on the suction and return lines.
3.Open the cover of the pump and empty the filter gasket .
4.Refit the cover
5.Open the valve to the drain outlet
6.Turn the lever to BACKWASH
7. Open the valves to the suction and return lines.
8.Start the pump .Rinse the filter for about 1 to 2 minutes until the water in the sight glass is clear .
NOTE : Any electric heater must be off .
