How to Change the Sande in Your Swimming Pool Filter
How often should the sand in a swimming pool filter be changed? We recommend changing the sand every five years. Filter sand has been ground to a size of .45 to .55 mm in diameter and is very rough when new. This roughness is what makes the sand efficient at filtering out the particles of dirt in your water. As this roughness is smoothed out your filter's efficiency goes down. This means that your system has to run more frequently to accomplish the same task.
