Sand Filter Service: When (and Why) You Should Change Your Filter Sand
Your sand filter is one of the most important parts of keeping your pool water clean and clear. Over time, the sand inside your filter wears down and becomes less effective at catching small debris. If you’re opening your pool for spring, this is the perfect time to check if your filter sand needs to be replaced. 
Why Changing Your Sand Matters
Pool filter sand naturally becomes smooth after years of use. When that happens, it can’t trap first and debris as well as it should.
Old sand can lead to:
- Cloudy water.
- Poor filtration.
- Increased chlorine demand.
Fresh sand helps your system run more efficiently and keeps your water looking crystal clear.
How Often Should You Change Filter Sand?
Most pool owners should change their filter sand every 3-5 years. However, heavy pool use or frequent water issues may require more frequent replacement. 
Tip: Prolong the life of your sand filter by using the Aquabrite Sandscrubber® cleaner.
Aquabrite Sandscrubber® removes the oils and grease from sand filters to promote better filtration. It works by thoroughly cleaning the sand to extend the sand’s life. It is recommended to use this at the end of swim season, before winterizing the pool.
Signs it’s Time to Replace Your Sand
Look for these common signs:
- Cloudy water that wont clear up.

- Frequent backwashing.
- High filter pressure.
- Sand returning to the pool.
- Ongoing algae problems.
If you’re noticing any of these, your sand may no longer be doing its job.
