A Practical Guide on How to Clean the Bottom of a Pool & When to Call a Professional

In Saudi Arabia, pool owners face unique challenges. Dust storms, wind, high temperatures, and frequent outdoor use can cause dirt, sand, and debris to accumulate at the bottom of the pool. If left untreated, these contaminants can affect water quality, strain filtration systems, and create an unpleasant swimming experience.

This guide explains how to properly clean the bottom of a pool, remove sand and dirt effectively, and determine when it’s time to call a professional pool maintenance company. Reza Pools & Courts provides pool construction, maintenance, repair, and renovation services throughout Saudi Arabia.

A reliable swimming pool cleaning service can help keep your pool clean, safe, and operating efficiently year-round. Understanding how to clean the bottom of a pool is an important part of proper maintenance, whether you own a residential, villa, hotel, or recreational facility pool.

Why Dirt Collects at the Bottom of a Pool

Pool floors naturally collect debris over time. Knowing the type of debris and conditions that accumulate helps determine the most effective cleaning approach.

Wind and Sandstorms: Fine dust and sand can settle quickly in outdoor pools, particularly during seasonal sandstorms.

Poor Water Circulation: Weak circulation allows debris to gather in corners, steps, and deep areas where water movement is limited.

Inadequate Filtration: Dirty, undersized, or poorly maintained filters struggle to remove fine particles from the water.

Heavy Pool Usage: Swimmers introduce dirt, sunscreen, body oils, and organic debris into the water, which eventually settles on the pool floor.

Identifying the Type of Debris in Your Pool

Before cleaning, identify what has accumulated on the bottom of the pool.

Dirt and Dust: Usually appears as brown, gray, or light-colored particles that settle evenly across the floor.

Sand: Heavier particles that often accumulate after windy conditions or sandstorms.

Algae: Green, yellow, or black growth that attaches to pool surfaces and may return quickly after cleaning.

Fine Particles: Very small contaminants that seem to disappear when disturbed and then settle again later.

Essential Tools You Need to Clean a Pool

Having the proper equipment makes pool cleaning faster and more effective.

Manual Pool Vacuum: Ideal for targeted cleaning and heavy debris removal.

Robotic Pool Cleaner: Provides automated cleaning for routine maintenance.

Pool Brush: Nylon brushes for fiberglass and vinyl pools, while stainless steel brushes for concrete and plaster pools.

Telescopic Pole and Skimmer Net: Useful for removing floating debris and reaching difficult areas.

Pool Filtration System: Whether you use a sand, cartridge, or DE (Diatomaceous Earth) filter, a properly functioning filtration system is essential for maintaining clear water.

Step-by-Step Guide on How to Clean the Bottom of a Pool

Step 1 – Remove Surface Debris

Start by skimming leaves, insects, and floating dirt from the surface. This prevents debris from sinking and creating additional buildup on the pool floor.

Step 2 – Brush Pool Walls and Floor

Before vacuuming, brush the walls, steps, corners, and waterline. Make sure to loosen the dirt, making it easier to remove. Choose the right brush according to the surface. Use softer brushes on fiberglass and vinyl pools and stronger brushes on concrete surfaces.

Step 3 – Vacuum the Pool Floor

If you’re wondering how to get dirt off the bottom of the pool surfaces effectively, proper vacuuming is often the best solution. If you’re using manual vacuuming, move slowly to avoid stirring debris back into the water. With the vacuum-to-waste method, you can bypass the filter and remove heavy dirt, algae, and debris directly from the pool. Opt for a robotic pool cleaner for convenient ongoing maintenance, reducing manual labor. 

Step 4 – Clean or Backwash the Filter

A dirty filter can return contaminants into the pool. Sand filters need cleaning; backwash them according to manufacturer recommendations. Cartridge filters should be removed and rinsed thoroughly. DE Filters should also be backwashed, and DE media replenished as needed.

Step 5 – Balance Pool Water

Proper water chemistry supports filtration performance and helps prevent algae growth. Balanced water helps maintain clarity and slows the accumulation of dirt. The recommended pH range is 7.2 to 7.6, and free chlorine is 1 to 3 ppm.

How to Remove Sand From the Pool Bottom

Many pool owners who have difficulty removing sand ask how to remove it from the bottom of their pool after a sandstorm. Fine sand settles rapidly and is easily disturbed during cleaning. Sand should be allowed to settle by temporarily turning off the circulation so particles sink before vacuuming. 

The best methods for sand removal use vacuum-to-waste to prevent sand from passing through the filtration system and re-entering the pool. Make sure to inspect the filter for broken laterals, which may cause sand to return to the pool.

How to Get Fine Dirt Out of Pool Water

Fine particles can be challenging because they often pass through standard filtration systems. The solution is to use a pool clarifier to bind small particles together, making them easier for filters to capture. In severe cases, flocculants cause particles to settle to the pool floor, where they can be vacuumed away.

It is recommended to extend filtration time, as running the pump longer helps improve particle removal. These methods are particularly effective if you’re trying to learn how to remove fine dirt from pool water after dust storms or heavy pool use.

Preventive Maintenance Tips

Preventing debris buildup is easier than dealing with major contamination later.

Maintain Weekly Cleaning: Routine vacuuming and brushing help keep the pool floor clean.

Use Pool Covers: Covers reduce contamination from wind, leaves, dust, and sand.

Improve Water Circulation: Proper pump operation helps eliminate dead spots where debris collects.

Schedule Professional Maintenance: Regular inspections can identify filtration and equipment issues before they become expensive repairs.
