How Much Earth Do You Put in a Pool Filter?

If you have recently installed a pool in your outdoor space, you know that it comes with a fair amount of maintenance. Keeping the water sparkling clean is perhaps the most important of all. To achieve that, you will need to invest in a good quality pool filter that ensures that impurities don't get into the water. That said, knowing how much earth you should put in a pool filter can be tricky. Here's what you need to know.

1. Why Do You Need Earth in a Pool Filter?

A pool filter makes use of a porous medium, earth, or diatomaceous earth, to trap dirt and debris. The water from the pool is pushed into the filter by a pump, which forces it through the medium, trapping any impurities along the way. The filtered water is then circulated back into the pool, ensuring that the water remains clean and clear. The earth is an essential part of the filtration process, as it acts as a fine sieve, capturing particles as small as 5 microns.

2. What Type of Earth Should You Use in a Pool Filter?

There are two main types of earth that you can use in a pool filter. Diatomaceous earth, or DE, is a type of sedimentary rock formed from the fossilized remains of diatoms, which are single-celled algae. It is mined, cleaned, and then ground into a fine, white powder. DE is a highly effective filter medium, but it also requires more attention than other filtering aids. On the other hand, you can opt for sand, which is much easier to use and requires less maintenance. However, sand is not as good as DE when it comes to catching smaller particles.

3. How Much Earth Should You Put in a Pool Filter?

The amount of earth you should put in a pool filter depends on the size of the filter and the manufacturer's instructions. DE filters typically require a bit more earth than sand filters. However, if you're unsure, consult the manual that came with your filter. In most cases, a DE filter will require about 4 to 8 pounds of earth per 10 square feet of filtration area. A sand filter, on the other hand, will require between 100 to 200 pounds of sand, depending on the size of the filter.

4. How Do You Add Earth to a Pool Filter?

Adding earth to a pool filter is a simple process, but you need to be careful not to overdo it. Start by turning off the pump and closing the filter's valves. Next, remove the lid of the filter and locate the filter element. If you have a DE filter, you will need to add the earth to the skimmer. If you have a sand filter, you will need to remove any old sand before adding the new. Pour the earth into the skimmer or filter with a scoop, taking care not to spill it. Once you've added the earth, reassemble the filter, turn the pump back on, and open the valves.

5. How Frequently Should You Replace the Earth in a Pool Filter?

The frequency at which you should change the earth in a pool filter depends on the type of filter you have and how often you use your pool. You should replace the earth in a DE filter at least once a year, or when the pressure gauge on the filter increases by 8 to 10 psi. For a sand filter, you should change the sand every three to five years, depending on how frequently you use your pool. A good rule of thumb is to inspect your filter regularly for any signs of wear and tear, and make adjustments as necessary.

In conclusion, knowing how much earth to put in a pool filter is critical to ensure that your pool remains clean and refreshing at all times. Consider the size of the filter, the manufacturer's instructions and be sure not to overdo it. Regular maintenance of your filter and timely replacement of the earth will ensure that your pool stays clean and clear, providing a safe and enjoyable space for you and your loved ones to relax and have fun.
