INYO understands how difficult it is locating information on an older or discontinued filter. As a result, we wanted to create a single, more succinct list of sand requirements for the most popular sand filters.
Using the charts below, you can find out how much sand you need for your specific make and model sand filter.
Which Sand Is Best For Your Pool

Mason sand is the best for your pool. Its also known as masonry sand or mortar sand. This sand is fine and free of sharp rocks and gravel. A good alternative to mason sand is concrete sand.
Its important to pick the best kind of sand for your pool. It needs to be free of gravel, glass pieces, and sharp rocks otherwise, it could tear holes in your pools lining.

How Much Sand Do You Need To Build A Pool
Its hard to beat the refreshing feeling of jumping into a pool in the middle of summer. But, the expenses with building a pool can add up very quickly. Building a pool of your own is one way of bringing that feeling home and getting to enjoy a dip whenever you want, while saving some money in the process.
If you decide to do part of the work in constructing a pool yourself, there are several materials you cannot substitute. Before taking the plunge, its important to keep in mind that sand is necessary when building an above ground pool. Thankfully, you can factor in how much sand youll need and how much it will ultimately cost you, by using a sand calculator.
How Do You Test Your Salt Levels
Its pretty simple. Your salt chlorine generator should give you a reading for how much salt is currently in your pool. However, if you dont have that reading, you can use a salt testing kit to get an accurate measurement. Once youve done that, youll know if youre above or below the ideal salt range that I mentioned above. If youre above it, youll need to replace your current pool water with new water. If youre below it, you add more salt.

Calculate How Much Sand You Will Need Using The Sand Calculator
You start by finding or building a straight 2×4 that is 1 foot longer than your pool diameter. In our case, we had a 15 ft pool so I attached two 2×4’s together to make one long 16 foot 2×4, as shown below. You will use this long 2×4 for leveling the sand as well along with any inexpensive carpenter’s level.. Click on photo to enlarge
Then, place one end of the 2×4 on the high side of your pool site and raise up the other end until it is level. Measure the distance in inches that you must raise the end up. In the photo below, I had to raise the end 4 inches. This distance is what you enter in the calculator below. Note that if you have more than a 2″ drop, you should level out your site by removing soil from the high side – otherwise you may have problems with the pool sinking into the softer end more. Then measure again.
MenuSwimming Pool Site Sand Calculator
Note that this calculator adds 3 feet to your diameter and calculates the sand to level your area. It then calculates an additional 2 inches of sand to place over the leveled area. If you have more than 2″ to level out, you should level out your area by removing soil from the high side first. Then remeasure.
Kidney Or Irregular Shapes
There are two methods used to calculate the capacity of irregular shapes. First, you can imagine the pool or hot tub as a combination of smaller, regular shapes. Measure these various areas and use the calculations described previously for each square or rectangular area and for each circular area. Add these volumes together to determine the total capacity.
0.45 x x length x average depth x 7.5 = volume
The total of measurement A plus measurement B multiplied by 0.45 multiplied by the length gives you the surface area of the kidney shape. . The rest of the calculations you are now familiar with. Try this volume calculation:
0.45 x x length x average depth x 7.5 = volume
0.45 x 18 ft x 25 ft x 5 ft x 7.5 = 7593.75 gallons
Parts Per Million
One of the most important calculations you will use is parts per million . The amount of solids and liquids in the water is measured in parts per million, as in three parts of chlorine in every one million parts of water, or 3 ppm.
To help, this list shows common terms and their equivalents:
Square foot = 12 inch wide x 12 inch long
Cubic foot = 12 inch wide x 12 inch long x 12 inch high
Cubic yard = 36 inch wide x 36 inch long x 36 inch high
One cubic foot of water contains 7.48 gallons
One cubic foot of water weighs 62.4 pounds
One gallon of water weighs 8.33 pounds
One part per million represents 8.3 pounds of chemical per million gallons of water.

Masonry Sand Volume Chart For Above Ground Pool Installations
Try to order by the yard if possible. Volume is more accurate than weight. Sand could have a high content of moisture and therefore weigh more. Always round up the next higher amount if they will not deliver 1/2 yards. There will generally be sand left over after the installation.
NOTE – VERY IMPORTANT: Always insist on masonry sand! Sand must not contain any rocks, stones, pebbles, twigs, trash, grass, etc. It must be pure, fine masonry sand.

When To Change Pool Filter Sand
This depends on the size of your sand filter in relation to the pool, but somewhere between 2-7 years.
Small sand filters of 16, 18 or 21 diameter need to replace the sand more often, every 2-5 years, sooner if the pool is used heavily, or has sticky tree debris, or a pump that is too large for the filter size.
Larger sand filters with 24 to 36 diameter tanks can often go longer between sand changes, simply because of the larger filter area. 5-7 years is the normal interval for larger sand filters.
The best time to replace filter sand is before you need to, but if you notice poor water quality, short filter cycles , or dirt passing through the filter, it may be time to replace the filter sand.
Types And Grades Of Sand
Contrary to what you may think, there is more than one type of sand, by the size of its pebbles and it’s intended use . Selecting the right type and size is crucial, as some sands have a different application than others.
