How often should I change the sand in my pool filter?

Dale Kreviazuk

This depends on how much dirt is going through your filter. Sand filters can work for a few years, up to 20 years with the same sand. This usually depends on maintaining a balanced pool chemistry, and opening up the waste valve when vacuuming up debris and algae. Some say that the sands sharp edges wear down over time, and cease to work as effectively, meaning that it should be replaced sooner rather than later. Ensure that you use filter cleanser to make sure the sand is not clumped together. Clumped sand causes the water to channel through the sand, and not actually be filtered.
