Factors to Consider When Buying Best Pool Filter Sand
When you set out to find the best type of sand for a 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.
Additionally, you might be tempted to simply take some sand from a nearby beach. This is potentially an even worse solution than playing 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.
Pool Filter Sand FAQ
Knowing what kind of sand for the 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.
Making the Decision
