Understanding De Filters
Diatomaceous Earth (DE) filters are a highly effective type of filtration system commonly used in swimming pools, spas, and even some home water filtration setups. They are known for their ability to remove extremely small particles, resulting in exceptionally clean water. Unlike sand or cartridge filters, DE filters utilize a powder made from the fossilized remains of diatoms, tiny aquatic organisms. This powder coats the filter grids, creating a cake-like structure that traps debris.
How De Filters Work
The core of a DE filter consists of a series of grids or fingers covered in a fabric or mesh. When the pump is turned on, water is forced through these grids. Before the water enters the filter, DE powder is added to the skimmer or directly into the filter housing. This powder coats the grids, forming a porous layer. As water passes through the DE-coated grids, the DE cake traps dirt, debris, and other contaminants.
As the filter collects debris, the pressure inside the filter increases, and the flow rate decreases. This indicates that the filter is becoming clogged and needs cleaning, a process known as backwashing.
Advantages of De Filters
- Superior Filtration: DE filters can remove particles as small as 5 microns, providing exceptional water clarity.
- Efficient: They are highly efficient at removing dirt, algae, and other contaminants.
- Versatile: Suitable for various applications, including pools, spas, and industrial water treatment.
Disadvantages of De Filters
- More Maintenance: Require more frequent backwashing and cleaning compared to other filter types.
- Cost: DE powder adds to the ongoing cost of operation.
- Complexity: More complex operation compared to cartridge filters.
Common Causes of Clogging
Several factors can lead to your DE filter clogging quickly. Identifying these causes is the first step in preventing and addressing the problem. Let’s explore some of the most common culprits.
Excessive Debris
One of the primary reasons a DE filter clogs quickly is an excessive amount of debris entering the system. This can include leaves, twigs, dirt, algae, and other organic matter. This is particularly prevalent during periods of heavy use or when the pool or spa is exposed to the elements.
- Leaves and Twigs: During windy conditions, leaves and twigs can easily blow into the pool and be drawn into the filter.
- Dirt and Dust: Airborne dirt and dust can settle on the water’s surface and eventually be filtered out.
- Algae Blooms: Algae can rapidly multiply in warm water, leading to a significant increase in the amount of organic material the filter must handle.
Improper Water Chemistry
Maintaining proper water chemistry is crucial for the efficient operation of your DE filter. Imbalances in pH, alkalinity, and calcium hardness can lead to mineral scale formation, which can clog the filter. Additionally, improper chlorine levels can hinder the filter’s performance.
- High Calcium Hardness: Excess calcium can precipitate out of the water and form scale, which can coat the filter grids.
- High pH: High pH levels can also contribute to scale formation.
- Low Chlorine: Insufficient chlorine levels can allow algae and bacteria to thrive, increasing the load on the filter.
Oil and Grease Contamination
Oils and grease from sources like suntan lotions, cosmetics, and body oils can coat the DE powder and filter grids, reducing their ability to trap debris. This can lead to rapid clogging and reduced filter efficiency. (See Also: How To Wash Birkenstock Clogs )
- Suntan Lotion: Suntan lotions and oils are a common source of oil contamination in pools.
- Cosmetics: Body lotions, makeup, and other cosmetics can also contribute to oil buildup.

Troubleshooting a Clogged De Filter
If your DE filter is clogging quickly, it’s essential to troubleshoot the problem to identify the root cause. Here’s a step-by-step guide to help you diagnose and resolve the issue.
1. Check the Pressure Gauge
The pressure gauge on your filter is a valuable tool for monitoring its performance. A sudden or gradual increase in pressure indicates that the filter is becoming clogged. Note the normal operating pressure when the filter is clean, and compare it to the current pressure reading.
- High Pressure: Indicates a clogged filter.
- Low Pressure: May indicate a leak or a problem with the pump.
- Fluctuating Pressure: Could indicate a problem with the pump or air in the system.
2. Backwash the Filter
Backwashing is the process of reversing the flow of water through the filter to remove accumulated debris. This is a crucial step in maintaining a DE filter. Follow these steps:
- Turn off the pump.
- Set the multiport valve to the “Backwash” setting.
- Turn the pump back on and run it for 2-3 minutes or until the water runs clear from the backwash line.
- Turn off the pump.
- Set the multiport valve to the “Rinse” setting.
- Turn the pump back on for 30-60 seconds to settle the DE powder.
- Turn off the pump.
- Set the multiport valve to the “Filter” setting.
- Turn the pump back on.
3. Remove and Clean the Filter Grids
If backwashing doesn’t resolve the issue, it’s time to remove and clean the filter grids. This involves disassembling the filter, removing the grids, and thoroughly cleaning them. This is a more involved process but often necessary for removing stubborn debris.
- Turn off the pump and release the pressure.
- Open the filter and carefully remove the grids.
- Rinse the grids with a garden hose, using a nozzle to direct the water.
