Best Sand for a Pool Filter:
Factors to Consider When Buying Best Pool Filter Sand
When you set out to find the best type of sand for pool filter, it can be helpful to have at least some knowledge of what makes a great pool filter sand. Here are some of the things you’ll need to consider when searching for the right sand for your filter.
It Needs to Be Filter-Specific
Often, the grains are much larger than the grains in filter sand. However, play sand grain sizing is not consistent. This means some grains may slip out of the filter and into your pool.
Additionally, you might be tempted to simply take some sand from a nearby beach. This is potentially an even worse solution than play sand. Sand from nature has the potential to introduce pathogens and other contaminants into your pool.
And since the point of a filter is to purify water, that would defeat the purpose.
Grain Size Matters
When shopping for filter sand, you may run into many pool filter sand types and sizes. You should expect pool filter sand to be between 0.45 and 0.55 mm.
This is a very fine grain size, and it’s known as #20 silica sand. Larger grain sizes create more space between each individual grain of sand. This lets more potential bits of debris and other contaminants slip through.
The Sand Type is Important
Reputable brands of pool filter sand use silica sand, which is superior when it comes to removing foreign particles from your pool water.
This means that the sand is a different type than pool filter sand, and it’s unlikely to be effective.
You Can Choose Alternative Filter Media
Some sand filter owners choose an alternative to natural sand. Alternative filter media are often made of different minerals than silica.
Many of these sand alternatives have a greater surface area per grain than sand, meaning it’s easier for them to trap debris. Some even use ion exchange to remove additional pollutants.
Most also require fewer pool backwashes, which ultimately saves money. Generally speaking, when using these sand alternatives, you can cut the required pounds of sand in half.
Pool Filter Sand FAQ
Knowing what kind of sand for pool filter you need and then buying it is the first step. But if you’re new to managing your own pool, you might have some questions about using pool sand. Here are some commonly asked questions:
How Much Sand Do I Need?
Most sand filters will require between 50 pounds and 300 pounds of filter sand. This usually depends on filter size and pressure as well as on the size of your pool.
However, the good news is that you don’t have to guess how much sand to buy–most pool filter manuals will tell you exactly how much sand you need in order to make sure the filter performs optimally.
How Often Should I Change Filter Sand?
While filter sand can be a challenge to replace, the good news is that you won’t need to change it often. On average, your filter sand will need to be changed every 3-5 years. This is because the edges of sand particles become worn over time, making them less effective at trapping particles of debris.
What Kinds of Things Does a Sand Filter Remove From Pool Water?
Sand filters can remove particles as small as 20-100 microns. However, these filters primarily remove insects, leaves, dirt, and other types of debris that fall into the pool. As more debris collects, sand filters can potentially remove even smaller particles.
