How Much Sand Do I Need For My Pool Filter

Introduction

Above ground pools need less maintenance than inground pools. The sand layer is necessary for both setups to cleanse it properly. It also prevents the pool lining from damage and the cultivation of algae.

Too much and too little sand is not good for your pool. You must know all the measurements to maintain the balance and run it correctly.

In this article, I will explain how you can identify the right amount of sand for your pool maintenance. So stay connected to know the exact quantity according to your DIY pool.

Factors to consider for pool filter

When constructing an inground or above ground pool, you must take deep notice of various factors. You need to give straight attention to all these factors, including:

1. Size of the pool
2. Type of the filter
3. Type of sand

1. Size of the pool

When we talk about the size of the pool, then the first thing that comes to mind is the standard length and width of the pool. So the average length of the rectangular pool is 15 ft wide and 50 ft long.

It is just an estimated size, so be clear about it. You can design it according to your desire and budget. There are three types of pool shapes.

These are round, oval, and rectangular. These shapes have their own approximated dimensions to fill up the sand. Let's see how these shapes are different in laying out sand.

1.1: The round shape pool

The round shape pools have a roundness that gives a perfect standing option in choosing the pool filter. It can store an efficient amount of water along with easy filtration.

Their length mainly starts from 12 ft and can extend to 30 ft in the round. The major calculation of using the sand depends on the pool yards and the condition of the pool base.

So once you construct the pool according to your length and width, try a sand calculator for pool for final calculations.

1.2: The oval shape pool

The oval-shaped pool offers you a maximum area to move around and swim. It is far better than the rectangular shaped pool. The balanced amount of sand helps you fill the pool accurately. It makes the water crystal clear and neat.

The most estimated or appropriate dimensions for an oval pool start from 12’ x 20’ and 21’ x 41’. The perfect size matters in the accurate performance of the pool.

So, according to this, you can set the level of the sand and prevent your tank from various damages, cultivation of vegetation, and teary lining.

1.3: Rectangular shape pool

Generally, rectangular shaped pools have one side larger than the other. They are perfect in geometrical shape and best designed for inground pools.

Their dimensions usually start from 10 x 20, 20 x 40, and what you want to construct. Each type or shape of the pool has different diameters, and the sand filter is manufactured according to these dimensions.

2. Types of sand filter

Another factor that needs proper attention is the right type of sand filter. Filter is the best choice to keep your pool neat and clean. it cleanses the sand from the water automatically. It gives a balanced amount of sand to use in the pool.

Otherwise, it may cause multiple problems. Just know that the large quantity of sand layer may destroy the filter. It increases the pressure of water and has adverse effects on filters.

It may break the filter and stop working. At the same time, the low amount of sand in the water may cause cloudiness or dirt in the pool.

Three main types of sand filters are:

1. Rapid sand filters
2. Upward flow sand filters
3. Slow sand filters

2.1: Rapid sand filters

The rapid sand filter works effectively and removes large dust particles. It automatically manages a large amount of sand layer.

2.2: Upward flow sand filters

The upward flow sand filter works best to remove the suspended particles of sand and soil. It cleanses the organic dirt and discolors the water.

Slow sand filters

This filter is best for removing the fine particles or concrete size of sand from water. It needs no backwashing for further procedure.

Calculate the right amount of sand

Calculating the right amount of sand for your pool is quite easy. Layering sand depends on the pool's size and prevents many leaks under the surface. However, it is estimated that the 2 inch sand layer is good.

But I suggest you measure the proper dimensions and area before layering the sand. It helps you fill the pool with an accurate amount of sand and provides more benefits.

Usually, the sand filters are 16 inches in diameter, so it needs 100 lbs to round around the pool. But the diameter varies as the size and shape of the pool differs. It started from 16 inches with 100 lbs towards 30 inches with 500 lbs.

3. Type of sand

There are different types of sand, but selecting appropriate sand is necessary. For example, you need sand for what purpose?

Which type of sand is suitable for your pool, and what quantity of sand is enough for your pool? There are some factors to considered when choosing sand, Therefore I bring four major types of sand to give you the best solution to your query.

1. Mason sand
2. Concrete sand
3. Silica sand
4. Glass sand

3.1: Mason sand

Mason sand is also known as mortar sand. It is free from all the stones, sharp rocks, and gravel. So if you want to prevent your pool from cracks, damage, sharp pieces of stones, pebbles, glass pieces, and holes, it will help you line in the comfort layer, not purify the pool water efficiently.

3.2: Concrete sand

Concrete sand is also known as paver sand. It creates a smooth base over stones, rocks, and deep holes. It is available in a fine powder texture which quickly heals all damages and packs all the stones together. The concrete sand gives strength and is not easily dispersed with the heavy flow of water. It makes the pool base easy to move on.

3.3: Silica sand

Silica sand is another sand used for pool filtration. It is mined from rocks not manufactured by machines. It is best for passing water and particulate sand most effectively. It is the best choice for a pool filter.

3.4: Glass sand

The glass sand is available in different sizes. It is smooth in texture and easy to touch. It cuts the water passage and goes through the filter directly. It minimizes channeling and is extremely good for a filled pool with hard water.

How can I calculate the amount of sand needed for my pool filter?

To calculate the amount of sand needed for your pool filter, you will need to consider several factors including the size of your pool, the type of filter you have, and the type of sand recommended for use in pool filters.

First, determine the size of your pool in square footage and the desired depth of sand in your filter. Most pool filters require a depth of 2-4 inches of sand.

Next, consult the manufacturer's specifications for the type of filter you have to determine the recommended amount of sand for that specific filter. This information can typically be found in the manual or online.

Finally, factor in the type of sand recommended for use in pool filters. Typically, #20 silica sand is recommended as it is specifically designed for pool filters and is less likely to cause problems.

Once you have all of this information, you can use a simple calculation to determine the number of pounds of sand needed for your filter. The formula is: Pool area (in square feet) x Desired depth of sand (in inches) / 20 (pounds per cubic foot) = Number of pounds of sand needed.

It is important to keep in mind that this is an estimate and it is always recommended to have a little extra on hand in case of any mistakes.

How to add sand to a pool filter?

To enhance the cleanliness of the pool water, you need to add sand to the pool filter. It is simple to DIY your pool filter with easy steps.

I suggested you with my personal experiences, which will help you in your pool maintenance. So let's move toward the simple and easy to understand steps.

1. Install a sand filter on your pool
2. Set the pipe position in the filter
3. Set the laterals accordingly
4. Fill the filter 75%
5. Activates the pool filter

1. Install a sand filter on your pool

Installation of sand filters is the main thing. Once you install the filter according to your pool size, it will become easy to add sand to it.

First, plug out or disconnect the filter and make appropriate settings. Attach the drain plug and get ready to move to the next step.

2. Set the pipe position in the filter

Once you install the sand filter, set the pipe position in it. Cover the pipe tip from the top with tape or any block.

Handle it carefully because the pipe is the filter's main source of spreading sand. And if the sand gets inside the pipe, it comes directly into the pool water, and the filter stops working. So carefully set it aside just before pouring the sand.

3. Set the laterals accordingly

The filter laterals or filter fingers are sensitive. They have multiple pipes, just like the tree branches. When you set the pipe location inside the filter, carefully set the laterals. These laterals help your pool filter drain the sand and rinse the remaining sand.

4. Fill the filter 75%

After setting the laterals properly, fill the filter with sand and water. Add almost 75% of water and 3 sandbags. The sand is estimated according to the size of your pool.

I have already mentioned how you can calculate the sand that you need. So bring the sandbags according to your pool size. Either it requires 1, 2, 3, or 4 sandbags. So carefully and slowly add the sand into the filter without any spill around it.

Tip: use only pool sand for the pool filter; otherwise, the alternate or anything else will ruin the filter.

5. Activate the pool filter

After completing the procedure, fix the filter, install the pipe, and fill the sand. Let's come forward to activate the pool filter. Screw down the O-cover and lateral pump. Plug in the filter and water connection.

Check the pressure gauge and set it to the normal pressure. Then set the filter's right glass clear and free it from dirt or debris. And now your filter is in a running position without any difficulty.

Tips for maintaining your filter to function properly

Here are multiple tips to maintain your filter for a long time. But it could be possible if you follow them regularly.

There is no science to protect your filter from damage, but proper care will increase its lifespan. So here are some easy tips to follow:
