How to know when it's time to change your pool filter media
"When should I change my pool filter media?"
If you've not heard the term Filter Media before, I apologize; it may be more of an Industry term for the material used inside the filter tank to trap the dirt.
For swimming pool filters, we have 3 types of Filter Media: Sand, Cartridges or Grids. Over time, all of these filter media types will need to be replaced.
Here's how to know when that time will be.
Lifespan of Filter Media Types:
Under Normal conditions, for well-maintained pools, Undersized filter systems or poor water balance can strain your filter media. In fact, the large range for cartridge filter replacement depends on how well sized the pool filter is. Larger pool filters, with more filter surface area, require less cleaning and changing of the media.
