Sand in Pool: Ways to Get Rid of It Effectively

Sand in pool can be a nuisance. The minute you start to enjoy the water, you feel it. It gets in your eyes, ears, nose, mouth… you name it. But did you know that there are many ways to get rid of it? Learn more here.

Sand in pool is a tricky little devil, which sometimes can be problematic. Over time, loose sand can coat the bottom of your swimming pool and even put swimmers at risk for an asthma attack or other respiratory complications.

No one likes to see the dark strands of sand on the pool’s surface, but even more, no one wants to spend all day scrubbing away at it with a brush. The sand in your pool is difficult to remove and can be dangerous for swimmers, so here are some tips on the best ways to remove it.

Why Is There Sand in Your Pool?

There are various ways that sand might get up at the bottom of your pool, and it may not be the way you expect.

Here’s what you need to know. 

Sand Can Easily Fall Into the Water.

When sand accumulates at the bottom of your pool, the most likely explanation is that it just dropped into the water.

This can happen even if there’s no source of sand surrounding your pool. 

Wind can pick up sand particles and transport them over vast distances. So the wind may carry sand straight into your pool while passing through the neighborhood.

However, if there’s a lot of sand in your pool’s bottom, this might not be the case.

Sand filters are used to remove particles such as sand and other dirt from pool water. However, if your sand filter develops a fracture or ceases to function correctly, it has the potential to discharge all of the sand back into your pool.

Did a Large Amount of Sand Accumulate in Your Pool in a Short Time?

It’s possible that you might need to clean your filter. It is mandatory to replace or repair a damaged filter before proceeding with the cleaning process.

If you know what you’re doing, you might be able to repair this problem independently. Nonetheless, if you don’t have much previous expertise with pool filters, it is recommended that you consult with a pool specialist before starting to remove the sand in your pool.

It’s Probably Not Sand

It is possible that the “sand” in the bottom of your pool is not sand at all. It may be yellow pool algae.

But how can you explain the difference between the two?

You are likely dealing with yellow pool algae (or mustard algae) if you have a sand filter installed in your swimming pool. Keep in mind that while the wind might blow sand in your pool, it will not blow a large amount at one time.

You may also try brushing some of the “sand” away. And if it produces a thick cloud in your swimming pool water, it’s probably mustard algae.

“Mustard algae can appear in your pool in a variety of ways, depending on the circumstances. It is possible to get mustard algae from natural sources such as weather conditions, or through contaminated items found in and near swimming pools, such as toys, rafts, and even swimsuits, which can spread the spores.”

To get rid of the algae, you’ll need to thoroughly clean your pool, as well as all of your pool equipment, pool toys, bathing suits, and everything else that comes into contact with the water. In addition, you should consult with a pool specialist about additional cleaning methods that can restore the safety of your water.

How to Clear the Sand in Pool

Getting rid of the sand in your pool isn’t difficult, but there’s a process to follow. It demands a little more effort than simply taking out the pool vacuum.

To begin, here’s what you should do.

Step 1. Prepare Your Vacuum

Although you cannot simply switch on your vacuum and start sucking, you will require one for this task.

Ensure that the multiport valve is set to the waste setting. If you vacuum with the “filter setting” selected, all of the sand in your pool gets trapped inside the vacuum cleaner, which can cause damage to the filter.

When the waste setting is on, pool water (and sand) are prevented from entering the filter. However, be prepared to lose a significant amount of water from your pool. Because the water does not pass through the filter, it will not cycle back to the pool. So you’ll be draining a large amount of pool water.

Step 2. Overfill Your Pool Above the Optimal Range

It would help if you overfilled the pool before you started vacuuming. The amount of sand present in the pool bottom will tell you how much water you’ll need to finish the cleaning process.

Step 3. Brush the Sand in One Spot

When it comes to cleaning, you’ll want to go quickly, so before you start to vacuum, grab your pool brush and sweep all of the sand into one place. Brushing down the pool’s walls can help remove any sand that sticks to the pool’s corners.

Spend some time brushing in the sharp edges of the pool. If you’re not too cautious, sand debris might end up sticking to the sides of the pool.

Take your time, and don’t rush. The more time you spend sweeping and brushing the sand into one area, the less time you’ll have to spend vacuuming it up afterward.

Step 4. Start Vacuuming the Sand Clump

Now that all of the sand has accumulated in one location, switch on your vacuum and move as quickly as possible.

However, avoid being overly concerned with the speed to the point that you become agitated or do poorly on the job. Keep in mind that you have already overfilled your pool. And if you end up losing more water than you anticipated, you can easily refill it back to the optimal range.

Your primary concern should be your safety.

Avoid rushing through the procedure to the point that you trip, fall or injure yourself. The sand at the bottom of your pool isn’t worth the risk of getting hurt. 

Tips to Keep “Sand in Pool” Situations at Bay and Maintain Your Filter

Beach Visits and Their Aftereffects

Beaches are perfect for relaxation, but they’re not always a pool’s best friend. One of the main culprits for “sand in pool” issues can be swimmers who’ve just returned from the beach. Sand from the shoreline can cling onto feet, clothes, and hair, eventually settling in your pool. Thorough rinsing after beach visits is an excellent preventive measure.

Unraveling the Sand Filter Mystery

A central part of pool hygiene is the sand filter, an intricate tank devised to filter out debris. However, if there’s sand in your pool and the nearest beach is miles away, chances are there’s an issue with your filter or an associated pipe. Ideally, water should traverse from the top-down inside the tank. If it’s entering from a side pipe, some tweaks are needed.

Guardians Inside: Standpipes and Laterals

Nestled inside your sand tank are the standpipes and laterals, whose primary job is to ensure no sand finds its way back into the pool. If these components falter, they can cause “sand in pool” problems. Regular inspections and timely replacements are essential to keep them in tip-top shape.

Backwashing: Your Filter’s Spa Treatment

Backwashing is akin to giving your sand filter a rejuvenating spa day. This process involves reversing the flow inside the filter, ensuring trapped debris and unwanted sand are expelled. Regular sessions keep your filter refreshed and your pool sand-free.

Role of Hoses and Drains in Maintenance

Hoses, especially the garden hose, play multifaceted roles in pool upkeep. They are handy for refilling and connecting to various equipment. On the sand filter’s end, the drain cap is pivotal. Occasional draining of the tank, ideally through a hose, ensures the filter system remains efficient. Storing key components like the drain cap safely is essential to prevent misplacement.

Leveling for Perfection

When addressing the “sand in pool” dilemma by adding or replacing sand in the filter tank, it’s vital to ensure an even level. This balance ensures optimal water flow and prevents tank system glitches.
