Swimming Pool Sand & Filter Sand - A Beginner's Introduction

When installing your above ground pool, you need to make sure that you use the correct type of swimming pool sand for the bottom of the pool and a different type of sand for your sand pool filter. The sand that lies underneath your pool is called “mason sand”, while the sand for your filter is simply called “filter sand” or
“silica sand”.

Mason Sand - For Your Pool’s Base

Mason sand, sometimes called mortar sand, can normally be found at any sand/gravel yard or masonry supply yard. It is usually measured in yards. It is very fine and should not contain any rocks or pebbles. This will create a very smooth bottom and is the most popular method to use when installing an above ground pool. You can call The Pool Factory to find out the correct amount of mason sand you will need for the size of the above ground pool you have in your backyard.

Silica Sand - For Your Sand Filter

Filter sand, or silica sand, is specially graded to trap very small particles. This is the type of sand your filter needs in order to properly clean your above ground pool. It is usually sold in 50lb bags and can be found in any pool store. One should always consult with their pool filters owner’s manual for exact sand requirements.
