How Much DE to Put in Pool Filter: A Comprehensive Guide

If you own a pool and want it to be in optimal condition, then you need to ensure that you're using the right amount of diatomaceous earth (DE). Using too much or too little DE can lead to problems that negatively impact the pool's health, user experience, and maintenance costs. In this guide, we'll teach you everything you need to know about how much DE to put in your pool filter, including the significance of DE, how to determine the right amount, and tips for optimizing its use.

What is Diatomaceous Earth (DE)?

Diatomaceous earth (DE) is a naturally occurring sedimentary rock that is made up of the fossilized remains of microscopic organisms called diatoms. When the silica shells of these fossilized diatoms are crushed, they form a powder that has excellent abrasive qualities. This powder is used in pool filters to help remove any unwanted debris and particles from the water, keeping it clean and clear.

Determining the Right Amount of DE

The amount of DE to put in your pool filter depends on the type of filter you have, its size, and the manufacturer's recommended specifications. You can typically find this information in the instruction manual or by contacting the manufacturer directly.

However, a general rule of thumb is to use one pound of DE per 10 square feet of filter surface area. If you have a D.E. filter with a surface area of 36 square feet, then you'll need approximately 3.6 pounds of DE. It's essential to note that using too much DE can cause harm to the filter's internal parts and the pool's plumbing system. On the other hand, using too little DE can decrease the filter's efficiency and cause a buildup of unwanted debris.

Tip: Measure the amount of DE you need by using a scale to ensure maximum accuracy.

Optimizing Your Use of DE

Now that you know how much DE to put in your pool filter let's talk about other factors to consider when using DE to keep your pool looking crystal clear.

1. Proper Application

When adding DE to your pool filter, it's best to dilute it in a bucket of water or mix it in the skimmer basket, allowing it to distribute evenly. Never add dry DE directly to the skimmer or the pool pump's strainer basket.

2. Regular Backwashing

Backwashing involves reversing the flow of water through the filter to clean out the DE and other debris that have built up. Regular backwashing keeps the filter functioning correctly and ensures maximum effectiveness.

3. Timely Replacement

Even with proper maintenance, DE breaks down over time and eventually loses its filtering ability. It's advisable to replace DE annually or as recommended by the manufacturer.

4. Protecting Your Health

While using DE can help keep your pool clean, you must take safety precautions when handling it, as inhaling DE dust can be harmful. We recommend using a respirator mask when measuring and pouring DE into the filter.

5. Alternative Filter Options

If you're looking for an alternative to a traditional DE filter, you can consider using other filter options such as sand or cartridge filters, which are easier to maintain and friendlier to the environment.

Conclusion

Knowing how much DE to put in your pool filter is vital to the overall health and maintenance of your pool. Not only does it ensure that your pool is clean and clear, but it can also prevent costly damage to your pool's internal parts and plumbing system. By following the guidelines discussed in this guide, you'll be well on your way to having a beautiful and healthy pool that will be the spot for summer fun and relaxation.
