When to Add Diatomaceous Earth to Pool Filter

Maintaining a clean and well-functioning pool filter is crucial to the overall health of your swimming pool. One of the most effective ways to ensure that your pool filter is functioning at its best is to add diatomaceous earth (DE). But when is the right time to add DE to your pool filter? In this article, we will provide you with everything you need to know about when to add diatomaceous earth to your pool filter, and how it can benefit your swimming pool.

What is Diatomaceous Earth?

Diatomaceous Earth, also known as DE, is a natural substance that is derived from the fossilized remains of diatoms, single-celled algae that existed millions of years ago. DE looks like a fine white powder, and it has a texture similar to flour. DE is commonly used in pool filters because of its unique ability to capture and filter out even the tiniest particles from your pool water.

Why is Diatomaceous Earth Essential for Your Pool Filter?

Your pool filter is designed to remove dirt, debris, and other contaminants from your pool water. However, if your filter is not working at its best, it can lead to cloudy water, algae growth, and other issues. DE is a crucial component of your pool filter because it functions as a filter media, trapping particles as small as 2-5 microns in size. Without DE, your filter would be unable to remove these tiny particles, which can cause a range of problems in your pool.

When Should You Add Diatomaceous Earth to Your Pool Filter?

One of the most common questions pool owners ask is when they should add DE to their pool filter. The answer to this question depends on several factors, including the size of your pool, the type of filter you have, and the rate at which your pool water becomes dirty.

As a general rule of thumb, you should add DE to your pool filter when your filter's pressure gauge reads 8-10 PSI higher than the starting pressure. For example, if your filter's starting pressure is 15 PSI, you should add DE when the pressure gauge reads between 23-25 PSI. This indicates that the filter is becoming clogged and needs to be cleaned and rehabilitated with DE.

Five Steps to Adding Diatomaceous Earth to Your Pool Filter

Now that you know when to add DE to your pool filter, let's take a look at the steps involved in doing so.

Step 1: Turn off the pool pump and close the skimmer valves.

Step 2: Open the filter drain valve and allow any water to drain out of the filter tank.

Step 3: Remove the filter's lid or top, and inspect the filter elements. Clean them thoroughly with a hose and brush if necessary.

Step 4: Add the appropriate amount of DE to the filter, based on the manufacturer's instructions. Be sure to add the correct amount, as too little DE will not filter the water properly, while too much can damage the filter.

Step 5: Replace the filter's lid or top, and turn the pool pump back on. Once the pump has re-primed, you can open the skimmer valves and resume normal pool operation.

Conclusion

Diatomaceous Earth is an essential component of your pool filter, and knowing when to add it can help your filter function correctly, keeping your pool water clean and healthy. By following the steps outlined in this article, you can add DE to your pool filter with confidence, ensuring that your pool stays crystal clear and inviting for many summers to come.
