How to clear cloudy pool water with sand filter? Amenity Pool Services in Port Charlotte have the answer for you

When the pool is clean, swimming becomes an enjoyable experience, and the pool owner is more likely to be satisfied. To maintain water clarity, it’s essential to properly care for the sand filter.  

Regular maintenance of the sand filter is crucial, as it ensures the pool remains clean and the water stays hygienic and free of cloudiness, such as the issues often seen with cloudy water in pools in Port Charlotte, Florida.  

According to Amenity Pool Services, the sand in a filter should be replaced every three to five years. Over time, the grains of sand become smooth and less effective at trapping dirt and debris.  

Before it’s time for a full sand replacement, pool owners can take several proactive steps to ensure their sand filter continues to operate at peak performance.  

What Is a Sand Filter?

A sand filter is basically a tank filled with sand that’s linked to your pool’s filtration system. When water flows through the sand tank, the sand traps debris and particles, stopping them from re-entering the pool. This leads to cleaner and clearer water.

What Size Sand Filter Do I Need?

The sand filter size you need depends on the size of your pool and its water capacity. If your inground pool holds up to 20,000 gallons, you’ll generally need a 24-inch diameter sand filter.  

For pools holding over 50,000 gallons, a 36-inch sand filter is recommended. Pools with 20,000 to 30,000 gallons usually need a filter between 24 to 30 inches. When choosing, it’s okay to go up a size, but don’t choose a smaller one. A smaller size may strain the system.  

Pool sand filter maintenance

Before you start, make sure to turn off the pump motor of the filter. Your sand filter has a multi-port valve you should know about. The usual setting for the filter is “filter,” as stated by Aquatic Training & Consulting services. When you need to clean it, switch the setting to “backwash.” This will let water go into the filter to clear out dirt and debris, and then the dirty water will flow out.

Steps to Change the Sand in Your Pool Filter 

Shut off the water flow and remove the top cover

  1. Close the bottom drain, skimmer, and vacuum valves. 
  2. Set the multiport valve to the “Closed” position to prevent leaks. 
  3. Remove the top cover of the filter or the multiport valve, depending on the model.  

Remove the old sand and inspect the laterals

  1. Use a scoop or a wet/dry vacuum to remove the old sand from the filter.  
  2. Inspect the laterals (also known as collector arms) at the bottom of the filter. Replace them if they are damaged or worn out.  

Clean the filter and refill with new sand

  1. Rinse the inside of the filter with water to remove any remaining debris. 
  2. Add water to the filter until it covers about 4 inches (10 cm) of the bottom.  
  3. Cover the central pipe with a plastic bag or cloth to prevent sand from entering it.  
  4. Slowly pour in the new sand until it reaches the level indicated by the manufacturer. 

Seal the cover, restore water flow, and perform an initial backwash

  1. Clean the O-ring and check that it’s in good condition before sealing the filter cover.  
  2. Open the valves you previously closed and set the multiport valve to the “Backwash” position.  
  3. Perform an initial backwash to remove dust from the new sand, followed by a rinse cycle to settle it.  
  4. You’ll then want to set the valve to “recirculate” which will circulate the water throughout the pool without putting it through the sand filter.  

Cloudy pool water and clear water in Florida pools

Will a sand filter clear cloudy water in Port Charlotte Fl? The perfect solution for your family

According to Aqua Magazine, filters are often the scapegoat for dirty pool water, when it’s usually the pool owner’s lack of vigilance that’s causing the filter to under-perform. 

Additionally, filters are sometimes overwhelmed by the number of unwanted materials in the pool such as hair, dirt or sunblock/suntan lotion.  

One useful tip for maintaining a clean pool is to add a coagulating agent to the water: This substance helps small particles and debris in the water stick together. It forms larger clumps or blobs.  

These clumps become heavier and sink to the bottom of the pool. This makes it easier to clean up later.  

Besides this method, the maintenance of a sand pool filter involves other simple steps that can greatly help in keeping the pool clean. For example, ensuring that everyone showers before they enter the pool helps to remove any dirt, sweat, or lotions that could contaminate the water.  

Furthermore, it is also important to keep the pool covered when it is not in use, as this will help prevent leaves, insects, and other debris from falling into the water.  

Helpful Tip: If you notice your sand forming clumps, try soaking it in a filter cleaner to get rid of them 

By following these recommendations, you can maintain a clearer and more inviting swimming environment.
