True! Best way to clean your sand if it has channeled or is fouled is to open the top of the filter to expose the sand bed, stick a garden hose in the sand and turn it on. As the water loosens up the sand all kinds of junk will float to the top and flow out the filter. GENTLY break up any clumps with something like a broom handle (but be VERY CAREFUL not to damage the laterals!). Do this until the overflowing water is basically clean.
IMHO, this should be done every year here in FL where pools are open year 'round, Depending on the length of your pool season and your water conditons YMMV!

(YMMV= your mileage may vary)
