How to Use Diatomaceous Earth in Pool Filter

If you have a swimming pool, then keeping the water clean and clear is crucial. One of the ways to ensure that your pool stays in pristine condition is to use a pool filter. But using just any pool filter won’t do the trick; you need to use one that is effective and efficient. Diatomaceous earth (DE) is a natural mineral that can be used in pool filters to improve their performance. Here, we will discuss how to use diatomaceous earth in a pool filter.

What is Diatomaceous Earth?

Diatomaceous earth is a natural, chalk-like mineral that is extracted from the remains of diatoms. These diatoms are tiny, single-celled organisms that lived millions of years ago in the oceans and in freshwater sources. Over time, their remains have been compressed and fossilized to form a unique type of sedimentary rock. This rock is then mined and processed to form the diatomaceous earth we know today.

Why Use Diatomaceous Earth in Pool Filters?

Pool filters are designed to remove impurities from the water in swimming pools. There are three types of pool filters: sand filters, cartridge filters, and DE filters. Of these, DE filters are the most efficient in removing impurities from the water. Diatomaceous earth acts as a filter medium and can trap particles as small as 2-5 microns. This makes it very effective in removing even the smallest impurities from the pool water, ensuring that the water is crystal clear and safe to swim in.

How to Use Diatomaceous Earth in Pool Filters

Using diatomaceous earth in a pool filter is a fairly easy process. Here’s how you can do it:

1. Turn off the pump and filter. Before you begin, make sure that your pool pump and filter are turned off. This is essential for your safety, as well as to prevent any damage to the pool filter.

2. Check the pressure gauge. Locate the pressure gauge on your filter and check its reading. If the pressure is higher than the normal operating range, then it’s time to clean the filter.

3. Remove the filter grid. Depending on the type of DE filter you have, you may need to unscrew or release some clamps to remove the filter grid. Once you have done this, you can remove the grid from the filter housing.

4. Clean the filter grid. Rinse the filter grid with a hose to remove any loose debris or dirt. Use a soft brush to scrub away any stubborn stains or dirt on the grid. Make sure to rinse the grid thoroughly before moving on to the next step.

5. Add diatomaceous earth. After cleaning the filter grid, you can now add the diatomaceous earth. The amount of DE you need to use will depend on the size of your filter. Refer to the manufacturer’s instructions for the correct amount to use. Slowly add the DE powder into the skimmer or where recommended by the manufacturer.

6. Reassemble the filter. Once you have added the diatomaceous earth, carefully replace the filter grid back into the filter housing. Make sure that it is securely in place and that all clamps and screws are tightened.

7. Turn on the pump and filter. Now that you have reassembled the filter, it’s time to turn on the pump and filter. Let the pump run for a few minutes to allow the DE to coat the filter grid. Check the pressure gauge to ensure that the pressure is within the normal operating range.

8. Backwash the filter. Eventually, the filter grid will become saturated with impurities and diatomaceous earth. At this point, you will need to backwash the filter. Refer to the manufacturer’s instructions for the correct way to do this. Backwashing involves reversing the flow of water through the filter to remove the impurities and DE.

Conclusion

In conclusion, using diatomaceous earth in a pool filter is an effective way to keep swimming pool water clean and safe. When using diatomaceous earth, make sure to follow the manufacturer’s instructions carefully and take the necessary safety precautions. With proper use and maintenance, your diatomaceous earth filter will keep your pool water crystal clear for years to come.
