My pool (ig 30,000 gal gunite) has just been replastered, and the pb s pushing to change the sand in the filter. I changed the sand in the filter
two years ago. While I have been battling algae all summer I am not convinced the sand needs to be changed as the pressure drops
back to initial level after very backwash?
what do you the gurus recommend?
Thanks
