One way would be that the water never really gets crystal clear. A good rule of thumb is change sand every 5 years. Of course use the correct grade of sand and use the filter manufacturers recommendations for the correct amount.

I used to change mine every year anyway, since sand is pretty cheap About every 4 years, or if you find that the pressure in the sand filter builds up too quickly.

∙ 15y agoWhy would you want to? Sand doesn't wear out. Sand Filters don't do a very good job of cleaning Pool water Until they develop a layer of hair, skin and other debris like bugs etc on top of the sand. Even then, a Cartridge Filter and DE Filter do a much better job.

∙ 12y agoIf you have a sand filter the sand needs replacing every 3 or four years. If you have a cartridge filter it wont need replacing until it breaks. Cartridge filters can become blocked over time causing the pressure to become to high as a result of the restricted flow of water, this can be fixed by getting an approved (for your filter) cleaner, this will clear the pores in the filter and keep it going so long as the membrane doesn't break.
