how much diatomaceous earth to use in pool filter

Diatomaceous earth, popularly referred to as DE, is a valuable product used in pool filters. Most pool owners have heard about diatomaceous earth as an effective filtration medium. It's recognized for its ability to filter out contaminants as tiny as debris and dust particles. Additionally, it's a safe and natural non-toxic way to clean and filter pool water.

In this article, we'll discuss how much diatomaceous earth to use in a pool filter.

What is Diatomaceous Earth?

Diatomaceous earth is a naturally occurring sedimentary rock composed of fossilized algae, known as diatoms. It's an environmentally friendly product that's used extensively in agriculture, household, and industrial settings for various purposes such as filtering, insecticide, and soil improvement.

Understanding Diatomaceous Earth Pool Filters

Diatomaceous earth pool filters function by passing water through a fine mesh made of fossilized diatoms. These filters work best when contaminated pool water goes through them, and the debris or dirt is captured inside the fine mesh. Typically, diatomaceous earth filters provide a low maintenance, high filtration solution to pool owners for every type of swimming pool.

How Much DE Should I Use?

When it comes to the question of how much diatomaceous earth to add to your pool filter, there are general guidelines that you can follow. For a properly functioning pool filter, you should aim to have the appropriate volume of DE in your filter. The recommended amount of DE to use depends on the size of your pool filter. Here's how much DE you should add according to your filter size:

- For a 24 to 36 square feet filter, add about 1 lb of DE

- For a 48 square feet filter, add about 2 lbs of DE

- For a 60 square feet filter, add about 2-1/2 lbs of DE

- For a 72 square feet filter, add about 3 lbs of DE

- For a 96 square feet filter, add about 4 lbs of DE

It's crucial to note that the above proportions are approximations. The right amount of DE to use depends on the filter product, and you should always read the product manual for instructions on usage.

How Often Should I Add DE?

The frequency of adding DE will vary depending on usage and the size of the pool. A general rule of thumb is to add DE to the filter after backwashing unless you're experiencing rapid increase of pressure.

How to Measure Diatomaceous Earth for Your Pool Filter

To achieve the best results and keep your filter running correctly, you should measure the diatomaceous earth before adding it to the pool filter.

Here is a simple recipe:

Step 1: Turn off the pump and ensure there's no water flowing through the filter.

Step 2: Open the filter and remove the old filter cake.

Step 3: Add the diatomaceous earth directly to the skimmer's hole.

Step 4: Use a bucket or measuring cup to weigh and pour the DE powder into the skimmer slowly.

Conclusion

Diatomaceous earth is an effective filtration medium that most pool owners use to keep their pool water clean and swimmer-friendly. However, it's essential to know how to use it to get the most out of it. You can use the general rule of thumb on how much DE to use, but it's always advisable to consult your manufacturer's manual for specific instructions. By doing so, you'll maintain healthy swimming pool water and a long-lasting filter.
